+}
+```
+
+## Prerequisites
+
+### For Podman MCP
+1. **Podman Desktop** installed and running
+2. Podman machine initialized and started:
+   ```powershell
+   podman machine init
+   podman machine start
+   ```
+
+### For Gitea MCP
+1. **Gitea MCP executable** at `d:\gitea-mcp\gitea-mcp.exe`
+2. **Gitea Access Tokens** with appropriate permissions:
+   - `repo` - Full repository access
+   - `write:user` - User profile access
+   - `read:organization` - Organization access
+
+### For Chrome DevTools MCP
+1. **Chrome browser** installed (stable channel)
+2. **Node.js 18+** for npx execution
+
+### For Markitdown MCP
+1. **Python 3.8+** installed
+2. **uvx** (universal virtualenv executor):
+   ```powershell
+   pip install uvx
+   ```
+
+## Testing MCP Servers
+
+### Test Podman Connection
+```powershell
+podman ps
+# Should list running containers
+```
+
+### Test Gitea API Access
+```powershell
+curl -H "Authorization: token YOUR_TOKEN" https://gitea.projectium.com/api/v1/user
+# Should return your user information
+```
+
+### Test Database Container
+```powershell
+podman exec flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev -c "SELECT version();"
+# Should return PostgreSQL version
+```
+
+## Security Notes
+
+### Token Management
+- **Never commit tokens** to version control
+- Store tokens in environment variables or secure password managers
+- Rotate tokens periodically
+- Use minimal required permissions
+
+### Access Tokens in Configuration Files
+The configuration files (`mcp.json` and `settings.json`) contain sensitive access tokens. These files should:
+- Be added to `.gitignore`
+- Have restricted file permissions
+- Be backed up securely
+- Be updated when tokens are rotated
+
+### Current Security Setup
+- `%APPDATA%\Code\User\mcp.json` - Gitea tokens embedded
+- `%USERPROFILE%\.claude\settings.json` - Gitea tokens embedded
+- Both files are in user-specific directories with appropriate Windows ACLs
+
+## Troubleshooting
+
+### Podman MCP Not Working
+1. Check Podman machine status:
+   ```powershell
+   podman machine list
+   ```
+2. Ensure Podman Desktop is running
+3. Verify Docker socket is accessible:
+   ```powershell
+   podman ps
+   ```
+
+### Gitea MCP Connection Issues
+1. Verify token has correct permissions
+2. Check network connectivity to Gitea server:
+   ```powershell
+   curl https://gitea.projectium.com/api/v1/version
+   ```
+3. Ensure `gitea-mcp.exe` is not blocked by antivirus/firewall
+
+### VS Code Extension Issues
+1. **Reload Window**: Press `Ctrl+Shift+P` → "Developer: Reload Window"
+2. **Check Extension Logs**: View → Output → Select extension from dropdown
+3. **Verify JSON Syntax**: Ensure both config files have valid JSON
+
+### MCP Server Not Loading
+1. Check config file syntax with JSON validator
+2. Verify executable paths are correct (use forward slashes or escaped backslashes)
+3. Ensure required dependencies are installed (Node.js, Python, etc.)
+4. Check VS Code developer console for errors: Help → Toggle Developer Tools
+
+## Adding New MCP Servers
+
+To add a new MCP server to both Gemini Code and Claude Code:
+
+1. **Install the MCP server** (if it's an npm package):
+   ```powershell
+   npm install -g @modelcontextprotocol/server-YOUR-SERVER
+   ```
+
+2. **Add to Gemini Code** (`mcp.json`):
+   ```json
+   {
+     "servers": {
+       "your-server-name": {
+         "type": "stdio",
+         "command": "npx",
+         "args": ["-y", "@modelcontextprotocol/server-YOUR-SERVER"],
+         "env": {}
+       }
+     }
+   }
+   ```
+
+3. **Add to Claude Code** (`settings.json`):
+   ```json
+   {
+     "mcpServers": {
+       "your-server-name": {
+         "command": "npx",
+         "args": ["-y", "@modelcontextprotocol/server-YOUR-SERVER"],
+         "env": {}
+       }
+     }
+   }
+   ```
+
+4. **Reload VS Code**
+
+## Current Project Integration
+
+### ADR Implementation Status
+- **ADR-0002**: Transaction Management ✅ Enforced
+- **ADR-0003**: Input Validation ✅ Enforced with URL validation
+
+### Database Setup
+- PostgreSQL 15 + PostGIS running in container
+- 63 tables created
+- URL constraints active:
+  - `flyers_image_url_check` enforces `^https?://.*`
+  - `flyers_icon_url_check` enforces `^https?://.*`
+
+### Development Workflow
+1. Start containers: `podman start flyer-crawler-postgres flyer-crawler-redis`
+2. Use MCP servers to manage development environment
+3. AI assistants can:
+   - Manage containers via Podman MCP
+   - Access repository via Gitea MCP

+
+## Gitea Workflows and CI/CD
+
+This project uses Gitea Actions for continuous integration and deployment. The workflows are located in `.gitea/workflows/`.
+
+### Available Workflows
+
+#### Automated Workflows
+
+**deploy-to-test.yml** - Automated deployment to test environment
+- **Trigger**: Automatically on every push to `main` branch
+- **Runner**: `projectium.com` (self-hosted)
+- **Process**:
+  1. Version bump (patch) with `[skip ci]` tag
+  2. TypeScript type-check and linting
+  3. Run unit tests + integration tests + E2E tests
+  4. Generate merged coverage report
+  5. Build React frontend for test environment
+  6. Deploy to `flyer-crawler-test.projectium.com`
+  7. Restart PM2 processes for test environment
+  8. Update database schema hash
+- **Coverage Report**: https://flyer-crawler-test.projectium.com/coverage
+- **Environment Variables**: Uses test database and Redis credentials
+
+#### Manual Workflows
+
+**deploy-to-prod.yml** - Manual deployment to production
+- **Trigger**: Manual via workflow_dispatch
+- **Confirmation Required**: Must type "deploy-to-prod"
+- **Process**:
+  1. Version bump (minor) for production release
+  2. Check database schema hash (fails if mismatch)
+  3. Build React frontend for production
+  4. Deploy to `flyer-crawler.projectium.com`
+  5. Restart PM2 processes (with version check)
+  6. Update production database schema hash
+- **Optional**: Force PM2 reload even if version matches
+
+**manual-db-backup.yml** - Database backup workflow
+- Creates timestamped backup of production database
+- Stored in `/var/backups/postgres/`
+
+**manual-db-restore.yml** - Database restore workflow
+- Restores production database from backup file
+- Requires confirmation and backup filename
+
+**manual-db-reset-test.yml** - Reset test database
+- Drops and recreates test database schema
+- Used for testing schema migrations
+
+**manual-db-reset-prod.yml** - Reset production database
+- **DANGER**: Drops and recreates production database
+- Requires multiple confirmations
+
+**manual-deploy-major.yml** - Major version deployment
+- Similar to deploy-to-prod but bumps major version
+- For breaking changes or major releases
+
+### Accessing Workflows via Gitea MCP
+
+With the Gitea MCP server configured, AI assistants can:
+- View workflow files
+- Monitor workflow runs
+- Check deployment status
+- Review CI/CD logs
+- Trigger manual workflows (via API)
+
+**Example MCP Operations**:
+```bash
+# Via Gitea MCP, you can:
+# - List recent workflow runs
+# - View workflow logs
+# - Check deployment status
+# - Review test results
+# - Monitor coverage reports
+```
+
+### Key Environment Variables for CI/CD
+
+The workflows use these Gitea repository secrets:
+
+**Database**:
+- `DB_HOST` - PostgreSQL host
+- `DB_USER` - Database user
+- `DB_PASSWORD` - Database password
+- `DB_DATABASE_PROD` - Production database name
+- `DB_DATABASE_TEST` - Test database name
+
+**Redis**:
+- `REDIS_PASSWORD_PROD` - Production Redis password
+- `REDIS_PASSWORD_TEST` - Test Redis password
+
+**API Keys**:
+- `VITE_GOOGLE_GENAI_API_KEY` - Production Gemini API key
+- `VITE_GOOGLE_GENAI_API_KEY_TEST` - Test Gemini API key
+- `GOOGLE_MAPS_API_KEY` - Google Maps Geocoding API key
+
+**Authentication**:
+- `JWT_SECRET` - JWT signing secret
+
+### Schema Migration Process
+
+The workflows use a schema hash comparison system:
+
+1. **Hash Calculation**: SHA-256 hash of `sql/master_schema_rollup.sql`
+2. **Storage**: Hashes stored in `public.schema_info` table
+3. **Comparison**: On each deployment, current hash vs deployed hash
+4. **Protection**: Deployment fails if schemas don't match
+
+**Manual Migration Steps** (when schema changes):
+1. Update `sql/master_schema_rollup.sql`
+2. Run manual migration workflow or:
+   ```bash
+   psql -U <user> -d <database> -f sql/master_schema_rollup.sql
+   ```
+3. Deploy will update hash automatically
+
+### PM2 Process Management
+
+The workflows manage three PM2 processes per environment:
+
+**Production** (`ecosystem.config.cjs --env production`):
+- `flyer-crawler-api` - Express API server
+- `flyer-crawler-worker` - Background job worker
+- `flyer-crawler-analytics-worker` - Analytics processor
+
+**Test** (`ecosystem.config.cjs --env test`):
+- `flyer-crawler-api-test` - Test Express API server
+- `flyer-crawler-worker-test` - Test background worker
+- `flyer-crawler-analytics-worker-test` - Test analytics worker
+
+**Process Cleanup**:
+- Workflows automatically delete errored/stopped processes
+- Version comparison prevents unnecessary reloads
+- Force reload option available for production
+
+### Monitoring Deployment via MCP
+
+Using Gitea MCP, you can monitor deployments in real-time:
+
+1. **Check Workflow Status**:
+   - View running workflows
+   - See step-by-step progress
+   - Read deployment logs
+
+2. **PM2 Process Monitoring**:

+# Flyer Crawler - Development Environment Setup
+
+Quick start guide for getting the development environment running with Podman containers.
+
+## Prerequisites
+
+- **Windows with WSL 2**: Install WSL 2 by running `wsl --install` in an administrator PowerShell
+- **Podman Desktop**: Download and install [Podman Desktop for Windows](https://podman-desktop.io/)
+- **Node.js 20+**: Required for running the application
+
+## Quick Start - Container Environment
+
+### 1. Initialize Podman
+
+```powershell
+# Start Podman machine (do this once after installing Podman Desktop)
+podman machine init
+podman machine start
+```
+
+### 2. Start Required Services
+
+Start PostgreSQL (with PostGIS) and Redis containers:
+
+```powershell
+# Navigate to project directory
+cd D:\gitea\flyer-crawler.projectium.com\flyer-crawler.projectium.com
+
+# Start PostgreSQL with PostGIS
+podman run -d \
+  --name flyer-crawler-postgres \
+  -e POSTGRES_USER=postgres \
+  -e POSTGRES_PASSWORD=postgres \
+  -e POSTGRES_DB=flyer_crawler_dev \
+  -p 5432:5432 \
+  docker.io/postgis/postgis:15-3.3
+
+# Start Redis
+podman run -d \
+  --name flyer-crawler-redis \
+  -e REDIS_PASSWORD="" \
+  -p 6379:6379 \
+  docker.io/library/redis:alpine
+```
+
+### 3. Wait for PostgreSQL to Initialize
+
+```powershell
+# Wait a few seconds, then check if PostgreSQL is ready
+podman exec flyer-crawler-postgres pg_isready -U postgres
+# Should output: /var/run/postgresql:5432 - accepting connections
+```
+
+### 4. Install Required PostgreSQL Extensions
+
+```powershell
+podman exec flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev -c "CREATE EXTENSION IF NOT EXISTS postgis; CREATE EXTENSION IF NOT EXISTS pg_trgm; CREATE EXTENSION IF NOT EXISTS \"uuid-ossp\";"
+```
+
+### 5. Apply Database Schema
+
+```powershell
+# Apply the complete schema with URL constraints enabled
+podman exec -i flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev < sql/master_schema_rollup.sql
+```
+
+### 6. Verify URL Constraints Are Enabled
+
+```powershell
+podman exec flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev -c "\d public.flyers" | grep -E "(image_url|icon_url|Check)"
+```
+
+You should see:
+```
+ image_url     | text                     |           | not null |
+ icon_url      | text                     |           | not null |
+Check constraints:
+    "flyers_icon_url_check" CHECK (icon_url ~* '^https?://.*'::text)
+    "flyers_image_url_check" CHECK (image_url ~* '^https?://.*'::text)
+```
+
+### 7. Set Environment Variables and Start Application
+
+```powershell
+# Set required environment variables
+$env:NODE_ENV="development"
+$env:DB_HOST="localhost"
+$env:DB_USER="postgres"
+$env:DB_PASSWORD="postgres"
+$env:DB_NAME="flyer_crawler_dev"
+$env:REDIS_URL="redis://localhost:6379"
+$env:PORT="3001"
+$env:FRONTEND_URL="http://localhost:5173"
+
+# Install dependencies (first time only)
+npm install
+
+# Start the development server (runs both backend and frontend)
+npm run dev
+```
+
+The application will be available at:
+- **Frontend**: http://localhost:5173
+- **Backend API**: http://localhost:3001
+
+## Managing Containers
+
+### View Running Containers
+```powershell
+podman ps
+```
+
+### Stop Containers
+```powershell
+podman stop flyer-crawler-postgres flyer-crawler-redis
+```
+
+### Start Containers (After They've Been Created)
+```powershell
+podman start flyer-crawler-postgres flyer-crawler-redis
+```
+
+### Remove Containers (Clean Slate)
+```powershell
+podman stop flyer-crawler-postgres flyer-crawler-redis
+podman rm flyer-crawler-postgres flyer-crawler-redis
+```
+
+### View Container Logs
+```powershell
+podman logs flyer-crawler-postgres
+podman logs flyer-crawler-redis
+```
+
+## Database Management
+
+### Connect to PostgreSQL
+```powershell
+podman exec -it flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev
+```
+
+### Reset Database Schema
+```powershell
+# Drop all tables
+podman exec -i flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev < sql/drop_tables.sql
+
+# Reapply schema
+podman exec -i flyer-crawler-postgres psql -U postgres -d flyer_crawler_dev < sql/master_schema_rollup.sql
+```
+
+### Seed Development Data
+```powershell
+npm run db:reset:dev
+```
+
+## Running Tests
+
+### Unit Tests
+```powershell
+npm run test:unit
+```
+
+### Integration Tests
+
+**IMPORTANT**: Integration tests require the PostgreSQL and Redis containers to be running.
+
+```powershell
+# Make sure containers are running
+podman ps
+
+# Run integration tests
+npm run test:integration
+```
+
+## Troubleshooting
+
+### Podman Machine Issues
+If you get "unable to connect to Podman socket" errors:
+```powershell
+podman machine start
+```
+
+### PostgreSQL Connection Refused
+Make sure PostgreSQL is ready:
+```powershell
+podman exec flyer-crawler-postgres pg_isready -U postgres
+```
+
+### Port Already in Use
+If ports 5432 or 6379 are already in use, you can either:
+1. Stop the conflicting service
+2. Change the port mapping when creating containers (e.g., `-p 5433:5432`)
+
+### URL Validation Errors
+The database now enforces URL constraints. All `image_url` and `icon_url` fields must:
+- Start with `http://` or `https://`
+- Match the regex pattern: `^https?://.*`
+
+Make sure the `FRONTEND_URL` environment variable is set correctly to avoid URL validation errors.
+
+## ADR Implementation Status
+
+This development environment implements:
+
+- **ADR-0002**: Transaction Management ✅
+  - All database operations use the `withTransaction` pattern
+  - Automatic rollback on errors
+  - No connection pool leaks
+
+- **ADR-0003**: Input Validation ✅
+  - Zod schemas for URL validation
+  - Database constraints enabled
+  - Validation at API boundaries
+
+## Development Workflow
+
+1. **Start Containers** (once per development session)
+   ```powershell
+   podman start flyer-crawler-postgres flyer-crawler-redis
+   ```
+
+2. **Start Application**
+   ```powershell
+   npm run dev
+   ```
+
+3. **Make Changes** to code (auto-reloads via `tsx watch`)
+
+4. **Run Tests** before committing
+   ```powershell
+   npm run test:unit
+   npm run test:integration
+   ```
+
+5. **Stop Application** (Ctrl+C)
+
+6. **Stop Containers** (optional, or leave running)
+   ```powershell
+   podman stop flyer-crawler-postgres flyer-crawler-redis
+   ```
+
+## PM2 Worker Setup (Production-like)
+
+To test with PM2 workers locally:
+
+```powershell
+# Install PM2 globally (once)
+npm install -g pm2
+
+# Start the worker
+pm2 start npm --name "flyer-crawler-worker" -- run worker:prod
+
+# View logs
+pm2 logs flyer-crawler-worker
+
+# Stop worker
+pm2 stop flyer-crawler-worker
+pm2 delete flyer-crawler-worker
+```
+
+## Next Steps
+
+After getting the environment running:
+
+1. Review [docs/adr/](docs/adr/) for architectural decisions
+2. Check [sql/master_schema_rollup.sql](sql/master_schema_rollup.sql) for database schema
+3. Explore [src/routes/](src/routes/) for API endpoints
+4. Review [src/types.ts](src/types.ts) for TypeScript type definitions
+
+## Common Environment Variables
+
+Create these environment variables for development:
+
+```powershell
+# Database
+$env:DB_HOST="localhost"
+$env:DB_USER="postgres"
+$env:DB_PASSWORD="postgres"
+$env:DB_NAME="flyer_crawler_dev"
+$env:DB_PORT="5432"
+
+# Redis
+$env:REDIS_URL="redis://localhost:6379"
+
+# Application
+$env:NODE_ENV="development"
+$env:PORT="3001"
+$env:FRONTEND_URL="http://localhost:5173"
+
+# Authentication (generate your own secrets)
+$env:JWT_SECRET="your-dev-jwt-secret-change-this"
+$env:SESSION_SECRET="your-dev-session-secret-change-this"
+
+# AI Services (get your own API keys)
+$env:VITE_GOOGLE_GENAI_API_KEY="your-google-genai-api-key"
+$env:GOOGLE_MAPS_API_KEY="your-google-maps-api-key"
+```

+# ADR-027: Standardized Naming Convention for AI and Database Types
+
+**Date**: 2026-01-05
+
+**Status**: Accepted
+
+## Context
+
+The application codebase primarily follows the standard TypeScript convention of `camelCase` for variable and property names. However, the PostgreSQL database uses `snake_case` for column names. Additionally, the AI prompts are designed to extract data that maps directly to these database columns.
+
+Attempting to enforce `camelCase` strictly across the entire stack created friction and ambiguity, particularly in the background processing pipeline where data moves from the AI model directly to the database. Developers were unsure whether to transform keys immediately upon receipt (adding overhead) or keep them as-is.
+
+## Decision
+
+We will adopt a hybrid naming convention strategy to explicitly distinguish between internal application state and external/persisted data formats.
+
+1. **Database and AI Types (`snake_case`)**:
+   Interfaces, Type definitions, and Zod schemas that represent raw database rows or direct AI responses **MUST** use `snake_case`.
+   - *Examples*: `AiFlyerDataSchema`, `ExtractedFlyerItemSchema`, `FlyerInsert`.
+   - *Reasoning*: This avoids unnecessary mapping layers when inserting data into the database or parsing AI output. It serves as a visual cue that the data is "raw", "external", or destined for persistence.
+
+2. **Internal Application Logic (`camelCase`)**:
+   Variables, function arguments, and processed data structures used within the application logic (Service layer, UI components, utility functions) **MUST** use `camelCase`.
+   - *Reasoning*: This adheres to standard JavaScript/TypeScript practices and maintains consistency with the rest of the ecosystem (React, etc.).
+
+3. **Boundary Handling**:
+   - For background jobs that primarily move data from AI to DB, preserving `snake_case` is preferred to minimize transformation logic.
+   - For API responses sent to the frontend, data should generally be transformed to `camelCase` unless it is a direct dump of a database entity for a specific administrative view.
+
+## Consequences
+
+### Positive
+
+- **Visual Distinction**: It is immediately obvious whether a variable holds raw data (`price_in_cents`) or processed application state (`priceInCents`).
+- **Efficiency**: Reduces boilerplate code for mapping keys (e.g., `price_in_cents: data.priceInCents`) when performing bulk inserts or updates.
+- **Simplicity**: AI prompts can request JSON keys that match the database schema 1:1, reducing the risk of mapping errors.
+
+### Negative
+
+- **Context Switching**: Developers must be mindful of the casing context.
+- **Linter Configuration**: May require specific overrides or `// eslint-disable-next-line` comments if the linter is configured to strictly enforce `camelCase` everywhere.

+# ADR-0005 Implementation Plan: Frontend State Management with TanStack Query
+
+**Date**: 2026-01-08
+**Status**: Ready for Implementation
+**Related ADR**: [ADR-0005: Frontend State Management and Server Cache Strategy](../docs/adr/0005-frontend-state-management-and-server-cache-strategy.md)
+
+## Current State Analysis
+
+### What We Have
+1. ✅ **TanStack Query v5.90.12 already installed** in package.json
+2. ❌ **Not being used** - Custom hooks reimplementing its functionality
+3. ❌ **Custom `useInfiniteQuery` hook** ([src/hooks/useInfiniteQuery.ts](../src/hooks/useInfiniteQuery.ts)) using `useState`/`useEffect`
+4. ❌ **Custom `useApiOnMount` hook** (inferred from UserDataProvider)
+5. ❌ **Multiple Context Providers** doing manual data fetching
+
+### Current Data Fetching Patterns
+
+#### Pattern 1: Custom useInfiniteQuery Hook
+**Location**: [src/hooks/useInfiniteQuery.ts](../src/hooks/useInfiniteQuery.ts)
+**Used By**: [src/providers/FlyersProvider.tsx](../src/providers/FlyersProvider.tsx)
+
+**Problems**:
+- Reimplements pagination logic that TanStack Query provides
+- Manual loading state management
+- Manual error handling
+- No automatic caching
+- No background refetching
+- No request deduplication
+
+#### Pattern 2: useApiOnMount Hook
+**Location**: Unknown (needs investigation)
+**Used By**: [src/providers/UserDataProvider.tsx](../src/providers/UserDataProvider.tsx)
+
+**Problems**:
+- Fetches data on mount only
+- Manual loading/error state management
+- No caching between unmount/remount
+- Redundant state synchronization logic
+
+## Implementation Strategy
+
+### Phase 1: Setup TanStack Query Infrastructure (Day 1)
+
+#### 1.1 Create QueryClient Configuration
+**File**: `src/config/queryClient.ts`
+
+```typescript
+import { QueryClient } from '@tanstack/react-query';
+
+export const queryClient = new QueryClient({
+  defaultOptions: {
+    queries: {
+      staleTime: 1000 * 60 * 5, // 5 minutes
+      gcTime: 1000 * 60 * 30,    // 30 minutes (formerly cacheTime)
+      retry: 1,
+      refetchOnWindowFocus: false,
+      refetchOnMount: true,
+    },
+    mutations: {
+      retry: 0,
+    },
+  },
+});
+```
+
+#### 1.2 Wrap App with QueryClientProvider
+**File**: `src/providers/AppProviders.tsx`
+
+Add TanStack Query provider at the top level:
+```typescript
+import { QueryClientProvider } from '@tanstack/react-query';
+import { ReactQueryDevtools } from '@tanstack/react-query-devtools';
+import { queryClient } from '../config/queryClient';
+
+export const AppProviders = ({ children }) => {
+  return (
+    <QueryClientProvider client={queryClient}>
+      {/* Existing providers */}
+      {children}
+      {/* Add devtools in development */}
+      {import.meta.env.DEV && <ReactQueryDevtools initialIsOpen={false} />}
+    </QueryClientProvider>
+  );
+};
+```
+
+### Phase 2: Replace Custom Hooks with TanStack Query (Days 2-5)
+
+#### 2.1 Replace useInfiniteQuery Hook
+
+**Current**: [src/hooks/useInfiniteQuery.ts](../src/hooks/useInfiniteQuery.ts)
+**Action**: Create wrapper around TanStack's `useInfiniteQuery`
+
+**New File**: `src/hooks/queries/useInfiniteFlyersQuery.ts`
+
+```typescript
+import { useInfiniteQuery } from '@tanstack/react-query';
+import * as apiClient from '../../services/apiClient';
+
+export const useInfiniteFlyersQuery = () => {
+  return useInfiniteQuery({
+    queryKey: ['flyers'],
+    queryFn: async ({ pageParam }) => {
+      const response = await apiClient.fetchFlyers(pageParam);
+      if (!response.ok) {
+        const error = await response.json();
+        throw new Error(error.message || 'Failed to fetch flyers');
+      }
+      return response.json();
+    },
+    initialPageParam: 0,
+    getNextPageParam: (lastPage) => lastPage.nextCursor ?? undefined,
+  });
+};
+```
+
+#### 2.2 Replace FlyersProvider
+
+**Current**: [src/providers/FlyersProvider.tsx](../src/providers/FlyersProvider.tsx)
+**Action**: Simplify to use TanStack Query hook
+
+```typescript
+import React, { ReactNode, useMemo } from 'react';
+import { FlyersContext } from '../contexts/FlyersContext';
+import { useInfiniteFlyersQuery } from '../hooks/queries/useInfiniteFlyersQuery';
+
+export const FlyersProvider: React.FC<{ children: ReactNode }> = ({ children }) => {
+  const {
+    data,
+    isLoading,
+    error,
+    fetchNextPage,
+    hasNextPage,
+    isRefetching,
+    refetch,
+  } = useInfiniteFlyersQuery();
+
+  const flyers = useMemo(
+    () => data?.pages.flatMap((page) => page.items) ?? [],
+    [data]
+  );
+
+  const value = useMemo(
+    () => ({
+      flyers,
+      isLoadingFlyers: isLoading,
+      flyersError: error,
+      fetchNextFlyersPage: fetchNextPage,
+      hasNextFlyersPage: !!hasNextPage,
+      isRefetchingFlyers: isRefetching,
+      refetchFlyers: refetch,
+    }),
+    [flyers, isLoading, error, fetchNextPage, hasNextPage, isRefetching, refetch]
+  );
+
+  return <FlyersContext.Provider value={value}>{children}</FlyersContext.Provider>;
+};
+```
+
+**Benefits**:
+- ~100 lines of code removed
+- Automatic caching
+- Background refetching
+- Request deduplication
+- Optimistic updates support
+
+#### 2.3 Replace UserDataProvider
+
+**Current**: [src/providers/UserDataProvider.tsx](../src/providers/UserDataProvider.tsx)
+**Action**: Use TanStack Query's `useQuery` for watched items and shopping lists
+
+**New Files**:
+- `src/hooks/queries/useWatchedItemsQuery.ts`
+- `src/hooks/queries/useShoppingListsQuery.ts`
+
+```typescript
+// src/hooks/queries/useWatchedItemsQuery.ts
+import { useQuery } from '@tanstack/react-query';
+import * as apiClient from '../../services/apiClient';
+
+export const useWatchedItemsQuery = (enabled: boolean) => {
+  return useQuery({
+    queryKey: ['watched-items'],
+    queryFn: async () => {
+      const response = await apiClient.fetchWatchedItems();
+      if (!response.ok) throw new Error('Failed to fetch watched items');
+      return response.json();
+    },
+    enabled,
+  });
+};
+
+// src/hooks/queries/useShoppingListsQuery.ts
+import { useQuery } from '@tanstack/react-query';
+import * as apiClient from '../../services/apiClient';
+
+export const useShoppingListsQuery = (enabled: boolean) => {
+  return useQuery({
+    queryKey: ['shopping-lists'],
+    queryFn: async () => {
+      const response = await apiClient.fetchShoppingLists();
+      if (!response.ok) throw new Error('Failed to fetch shopping lists');
+      return response.json();
+    },
+    enabled,
+  });
+};
+```
+
+**Updated Provider**:
+```typescript
+import React, { ReactNode, useMemo } from 'react';
+import { UserDataContext } from '../contexts/UserDataContext';
+import { useAuth } from '../hooks/useAuth';
+import { useWatchedItemsQuery } from '../hooks/queries/useWatchedItemsQuery';
+import { useShoppingListsQuery } from '../hooks/queries/useShoppingListsQuery';
+
+export const UserDataProvider: React.FC<{ children: ReactNode }> = ({ children }) => {
+  const { userProfile } = useAuth();
+  const isEnabled = !!userProfile;
+
+  const { data: watchedItems = [], isLoading: isLoadingWatched, error: watchedError } =
+    useWatchedItemsQuery(isEnabled);
+
+  const { data: shoppingLists = [], isLoading: isLoadingLists, error: listsError } =
+    useShoppingListsQuery(isEnabled);
+
+  const value = useMemo(
+    () => ({
+      watchedItems,
+      shoppingLists,
+      isLoading: isEnabled && (isLoadingWatched || isLoadingLists),
+      error: watchedError?.message || listsError?.message || null,
+    }),
+    [watchedItems, shoppingLists, isEnabled, isLoadingWatched, isLoadingLists, watchedError, listsError]
+  );
+
+  return <UserDataContext.Provider value={value}>{children}</UserDataContext.Provider>;
+};
+```
+
+**Benefits**:
+- ~40 lines of code removed
+- No manual state synchronization
+- Automatic cache invalidation on user logout
+- Background refetching
+
+### Phase 3: Add Mutations for Data Modifications (Days 6-8)
+
+#### 3.1 Create Mutation Hooks
+
+**Example**: `src/hooks/mutations/useAddWatchedItemMutation.ts`
+
+```typescript
+import { useMutation, useQueryClient } from '@tanstack/react-query';
+import * as apiClient from '../../services/apiClient';
+import { notifySuccess, notifyError } from '../../services/notificationService';
+
+export const useAddWatchedItemMutation = () => {
+  const queryClient = useQueryClient();
+
+  return useMutation({
+    mutationFn: apiClient.addWatchedItem,
+    onSuccess: () => {
+      // Invalidate and refetch watched items
+      queryClient.invalidateQueries({ queryKey: ['watched-items'] });
+      notifySuccess('Item added to watched list');
+    },
+    onError: (error: Error) => {
+      notifyError(error.message || 'Failed to add item');
+    },
+  });
+};
+```
+
+#### 3.2 Implement Optimistic Updates
+
+**Example**: Optimistic shopping list update
+
+```typescript
+export const useUpdateShoppingListMutation = () => {
+  const queryClient = useQueryClient();
+
+  return useMutation({
+    mutationFn: apiClient.updateShoppingList,
+    onMutate: async (newList) => {
+      // Cancel outgoing refetches
+      await queryClient.cancelQueries({ queryKey: ['shopping-lists'] });
+
+      // Snapshot previous value
+      const previousLists = queryClient.getQueryData(['shopping-lists']);
+
+      // Optimistically update
+      queryClient.setQueryData(['shopping-lists'], (old) =>
+        old.map((list) => (list.id === newList.id ? newList : list))
+      );
+
+      return { previousLists };
+    },
+    onError: (err, newList, context) => {
+      // Rollback on error
+      queryClient.setQueryData(['shopping-lists'], context.previousLists);
+      notifyError('Failed to update shopping list');
+    },
+    onSettled: () => {
+      // Always refetch after error or success
+      queryClient.invalidateQueries({ queryKey: ['shopping-lists'] });
+    },
+  });
+};
+```
+
+### Phase 4: Remove Old Custom Hooks (Day 9)
+
+#### Files to Remove:
+- ❌ `src/hooks/useInfiniteQuery.ts` (if not used elsewhere)
+- ❌ `src/hooks/useApiOnMount.ts` (needs investigation)
+
+#### Files to Update:
+- Update any remaining usages in other components
+
+### Phase 5: Testing & Documentation (Day 10)
+
+#### 5.1 Update Tests
+- Update provider tests to work with QueryClient
+- Add tests for new query hooks
+- Add tests for mutation hooks
+
+#### 5.2 Update Documentation
+- Mark ADR-0005 as **Accepted** and **Implemented**
+- Add usage examples to documentation
+- Update developer onboarding guide
+

+# ADR-0005 Phase 2 Implementation Summary
+
+**Date**: 2026-01-08
+**Status**: ✅ Complete
+
+## Overview
+
+Successfully completed Phase 2 of ADR-0005 enforcement by migrating all remaining query-based data fetching to TanStack Query.
+
+## Files Created
+
+### Query Hooks
+
+1. **[src/hooks/queries/useMasterItemsQuery.ts](../src/hooks/queries/useMasterItemsQuery.ts)**
+   - Fetches all master grocery items
+   - 10-minute stale time (data changes infrequently)
+   - 30-minute garbage collection time
+
+2. **[src/hooks/queries/useFlyerItemsQuery.ts](../src/hooks/queries/useFlyerItemsQuery.ts)**
+   - Fetches items for a specific flyer
+   - Per-flyer caching (separate cache for each flyer_id)
+   - Automatically disabled when no flyer ID provided
+   - 5-minute stale time
+
+## Files Modified
+
+### Providers
+
+1. **[src/providers/MasterItemsProvider.tsx](../src/providers/MasterItemsProvider.tsx)**
+   - **Before**: 32 lines using `useApiOnMount` with manual state management
+   - **After**: 31 lines using `useMasterItemsQuery` (cleaner, no manual callbacks)
+   - Removed: `useEffect`, `useCallback`, `logger` imports
+   - Removed: Debug logging for mount/unmount
+   - Added: Automatic caching and background refetching
+
+### Custom Hooks
+
+2. **[src/hooks/useFlyerItems.ts](../src/hooks/useFlyerItems.ts)**
+   - **Before**: 29 lines with custom wrapper and `useApiOnMount`
+   - **After**: 32 lines using `useFlyerItemsQuery` (more readable)
+   - Removed: Complex wrapper function for type satisfaction
+   - Removed: Manual `enabled` flag handling
+   - Added: Automatic per-flyer caching
+
+## Code Reduction Summary
+
+### Phase 1 + Phase 2 Combined
+- **Total custom state management code removed**: ~200 lines
+- **New query hooks created**: 5 files (~200 lines of standardized code)
+- **Providers simplified**: 4 files
+- **Net result**: Cleaner, more maintainable codebase with better functionality
+
+## Technical Improvements
+
+### 1. Intelligent Caching Strategy
+```typescript
+// Master items (rarely change) - 10 min stale time
+useMasterItemsQuery() // staleTime: 10 minutes
+
+// Flyers (moderate changes) - 2 min stale time
+useFlyersQuery() // staleTime: 2 minutes
+
+// User data (frequent changes) - 1 min stale time
+useWatchedItemsQuery() // staleTime: 1 minute
+useShoppingListsQuery() // staleTime: 1 minute
+
+// Flyer items (static) - 5 min stale time
+useFlyerItemsQuery() // staleTime: 5 minutes
+```
+
+### 2. Per-Resource Caching
+Each flyer's items are cached separately:
+```typescript
+// Flyer 1 items cached with key: ['flyer-items', 1]
+useFlyerItemsQuery(1)
+
+// Flyer 2 items cached with key: ['flyer-items', 2]
+useFlyerItemsQuery(2)
+
+// Both caches persist independently
+```
+
+### 3. Automatic Query Disabling
+```typescript
+// Query automatically disabled when flyerId is undefined
+const { data } = useFlyerItemsQuery(selectedFlyer?.flyer_id);
+// No manual enabled flag needed!
+```
+
+## Benefits Achieved
+
+### Performance
+- ✅ **Reduced API calls** - Data cached between component unmounts
+- ✅ **Background refetching** - Stale data updates in background
+- ✅ **Request deduplication** - Multiple components can use same query
+- ✅ **Optimized cache times** - Different strategies for different data types
+
+### Code Quality
+- ✅ **Removed ~50 more lines** of custom state management
+- ✅ **Eliminated useApiOnMount** from all providers
+- ✅ **Standardized patterns** - All queries follow same structure
+- ✅ **Better type safety** - TypeScript types flow through queries
+
+### Developer Experience
+- ✅ **React Query Devtools** - Inspect all queries and cache
+- ✅ **Easier debugging** - Clear query states and transitions
+- ✅ **Less boilerplate** - No manual loading/error state management
+- ✅ **Automatic retries** - Failed queries retry automatically
+
+### User Experience
+- ✅ **Faster perceived performance** - Cached data shows instantly
+- ✅ **Fresh data** - Background refetching keeps data current
+- ✅ **Better offline handling** - Cached data available offline
+- ✅ **Smoother interactions** - No loading flicker on re-renders
+
+## Remaining Work
+
+### Phase 3: Mutations (Next)
+- [ ] Create mutation hooks for data modifications
+- [ ] Add/remove watched items with optimistic updates
+- [ ] Shopping list CRUD operations
+- [ ] Proper cache invalidation strategies
+
+### Phase 4: Cleanup (Final)
+- [ ] Remove `useApiOnMount` hook entirely
+- [ ] Remove `useApi` hook if no longer used
+- [ ] Remove stub implementations in providers
+- [ ] Update all dependent tests
+
+## Testing Recommendations
+
+Before merging, test the following:
+
+1. **Flyer List**
+   - Flyers load on page load
+   - Flyers cached on navigation away/back
+   - Background refetch after stale time
+
+2. **Flyer Items**
+   - Items load when flyer selected
+   - Each flyer's items cached separately
+   - Switching between flyers uses cache
+
+3. **Master Items**
+   - Items available across app
+   - Long cache time (10 min)
+   - Shared across all components
+
+4. **User Data**
+   - Watched items/shopping lists load on login
+   - Data cleared on logout
+   - Fresh data on login (not stale from previous user)
+
+5. **React Query Devtools**
+   - Open devtools in development
+   - Verify query states and cache
+   - Check background refetching behavior
+
+## Migration Notes
+
+### Breaking Changes
+None! All providers maintain the same interface.
+
+### Deprecation Warnings
+The following will log warnings if used:
+- `setWatchedItems()` in UserDataProvider
+- `setShoppingLists()` in UserDataProvider
+
+These will be removed in Phase 4 after mutations are implemented.
+
+## Documentation Updates
+
+- [x] Updated [ADR-0005](../docs/adr/0005-frontend-state-management-and-server-cache-strategy.md)
+- [x] Created [Phase 2 Summary](./adr-0005-phase-2-summary.md)
+- [ ] Update component documentation (if needed)
+- [ ] Update developer onboarding guide (Phase 4)
+
+## Conclusion
+
+Phase 2 successfully migrated all remaining query-based data fetching to TanStack Query. The application now has a consistent, performant, and maintainable approach to server state management.
+
+**Next Steps**: Proceed to Phase 3 (Mutations) when ready to implement data modification operations.

+
+## Current Status: MCP Server Tool Availability
+
+**Important Note**: While these MCP servers are configured in your environment, they are **not currently exposed as callable tools** in this Claude Code session. 
+
+### What This Means:
+
+MCP servers typically work by:
+1. Running as separate processes
+2. Exposing tools and resources via the Model Context Protocol
+3. Being connected to the AI assistant by the client application (VSCode)
+
+### Current Situation:
+
+In the current session, Claude Code has access to:
+- ✅ Built-in file operations (read, write, search, list)
+- ✅ Browser actions
+- ✅ Mode switching
+- ✅ Task management tools
+
+But does **NOT** have direct access to:
+- ❌ MCP server-specific tools (e.g., Gitea API operations)
+- ❌ Chrome DevTools controls
+- ❌ Markitdown conversion functions
+- ❌ Docker container management
+- ❌ Specialized fetch operations
+
+### Why This Happens:
+
+MCP servers need to be:
+1. Actively connected by the client (VSCode)
+2. Running in the background
+3. Properly registered with the AI assistant
+
+The configuration files show they are set up, but the connection may not be active in this particular session.
+
+---
+
+## Testing Your MCP Servers
+
+Three approaches to verify your MCP servers are working:
+
+### Approach 1: Run the Automated Test Script
+
+Execute the provided PowerShell script to test all servers:
+
+```powershell
+cd plans
+.\test-mcp-servers.ps1
+```
+
+This will:
+- Test each server's basic functionality
+- Check API connectivity for Gitea servers
+- Verify Docker daemon access
+- Test filesystem accessibility
+- Output a detailed results report
+
+### Approach 2: Use MCP Inspector
+
+Install and use the official MCP testing tool:
+
+```powershell
+# Install
+npm install -g @modelcontextprotocol/inspector
+
+# Test individual servers
+mcp-inspector npx -y @modelcontextprotocol/server-fetch
+mcp-inspector npx -y @modelcontextprotocol/server-filesystem "D:\gitea\flyer-crawler.projectium.com\flyer-crawler.projectium.com"
+```
+
+The inspector provides a web UI to:
+- View available tools
+- Test tool invocations
+- See real-time logs
+- Debug server issues
+
+### Approach 3: Manual Testing
+
+Follow the comprehensive guide in [`mcp-server-testing-guide.md`](plans/mcp-server-testing-guide.md:1) for step-by-step manual testing instructions.
+
+---
+
+## Recommendations
+
+### 1. Immediate Actions
+
+- [ ] **Fix Gitea LAN token**: Generate and configure a valid access token for gitea.torbolan.com
+- [ ] **Run test script**: Execute `test-mcp-servers.ps1` to verify all servers
+- [ ] **Review test results**: Check which servers are functional
+- [ ] **Document failures**: Note any servers that fail testing
+
+### 2. Security Improvements
+
+- [ ] **Rotate Gitea tokens**: Consider rotating access tokens if they're old
+- [ ] **Review token permissions**: Ensure tokens have minimal required permissions
+- [ ] **Audit filesystem scope**: Verify filesystem server only has access to intended directories
+- [ ] **Secure token storage**: Consider using environment variables or secret management
+- [ ] **Enable audit logging**: Track MCP server operations for security monitoring
+
+### 3. Configuration Optimization
+
+- [ ] **Consolidate configs**: Both `mcp.json` and `mcp-servers.json` have identical content - determine which is canonical
+- [ ] **Add error handling**: Configure timeout and retry settings for network-dependent servers
+- [ ] **Document usage patterns**: Create examples of common operations for each server
+- [ ] **Set up monitoring**: Track MCP server health and availability
+
+### 4. Integration and Usage
+
+- [ ] **Verify VSCode integration**: Ensure MCP servers are actually connected in active sessions
+- [ ] **Test tool availability**: Confirm which MCP tools are exposed to Claude Code
+- [ ] **Create usage examples**: Document real-world usage scenarios
+- [ ] **Set up aliases**: Create shortcuts for commonly-used MCP operations

+
+## Using MCP Inspector for Interactive Testing
+
+The MCP Inspector provides a visual interface for testing servers:
+
+```bash
+# Install globally
+npm install -g @modelcontextprotocol/inspector
+
+# Test any server
+mcp-inspector <command> <args>
+```
+```powershell
+# Install globally
+npm install -g @modelcontextprotocol/inspector
+
+# Test any server
+mcp-inspector <command> <args>
+```
+
+### Example Sessions:
+
+```bash
+# Test fetch server
+mcp-inspector npx -y @modelcontextprotocol/server-fetch
+
+# Test filesystem server
+mcp-inspector npx -y @modelcontextprotocol/server-filesystem "D:\gitea\flyer-crawler.projectium.com\flyer-crawler.projectium.com"
+
+# Test Docker server
+mcp-inspector npx -y @modelcontextprotocol/server-docker
+```
+```powershell
+# Test fetch server
+mcp-inspector npx -y @modelcontextprotocol/server-fetch
+
+# Test filesystem server
+mcp-inspector npx -y @modelcontextprotocol/server-filesystem "D:\gitea\flyer-crawler.projectium.com\flyer-crawler.projectium.com"
+
+# Test Docker server
+mcp-inspector npx -y @modelcontextprotocol/server-docker
+```
+
+---
+
+## Common Issues and Solutions
+
+### Issue: "Cannot find module" or "Command not found"
+**Solution**: Ensure Node.js and npm are installed and in PATH
+
+### Issue: MCP server starts but doesn't respond
+**Solution**: Check server logs, verify stdio communication, ensure no JSON parsing errors
+
+### Issue: Authentication failures with Gitea
+**Solution**: 
+1. Verify tokens haven't expired
+2. Check token permissions in Gitea settings
+3. Ensure network access to Gitea instances
+
+### Issue: Docker server cannot connect
+**Solution**:
+1. Start Docker Desktop
+2. Verify DOCKER_HOST environment variable
+3. Check Windows named pipe permissions
+
+---
+
+## Next Steps
+
+After testing:
+1. Document which servers are working
+2. Fix any configuration issues
+3. Update tokens as needed
+4. Consider security implications of exposed servers
+5. Set up monitoring for server health
+
+---
+
+## Security Recommendations
+
+1. **Token Security**: Keep Gitea tokens secure, rotate regularly
+2. **Filesystem Access**: Limit filesystem server scope to necessary directories
+3. **Network Access**: Consider firewall rules for external MCP servers
+4. **Audit Logging**: Enable logging for all MCP server operations
+5. **Token Permissions**: Use minimal required permissions for Gitea tokens

+# Podman MCP Server Test Results
+
+**Date**: 2026-01-08
+**Status**: Configuration Complete ✅
+
+## Configuration Summary
+
+### MCP Configuration File
+**Location**: `c:/Users/games3/AppData/Roaming/Code/User/mcp.json`
+
+```json
+"podman": {
+    "command": "npx",
+    "args": ["-y", "docker-mcp"],
+    "env": {
+        "DOCKER_HOST": "ssh://root@127.0.0.1:2972/run/podman/podman.sock"
+    }
+}
+```
+
+### Key Configuration Details
+- **Package**: `docker-mcp` (community MCP server with SSH support)
+- **Connection Method**: SSH to Podman machine
+- **SSH Endpoint**: `root@127.0.0.1:2972`
+- **Socket Path**: `/run/podman/podman.sock` (inside WSL)
+
+## Podman System Status
+
+### Podman Machine
+```
+NAME                    VM TYPE     CREATED      CPUS        MEMORY      DISK SIZE
+podman-machine-default  wsl         4 weeks ago  4           2GiB        100GiB
+```
+
+### Connection Information
+```
+Name:     podman-machine-default-root
+URI:      ssh://root@127.0.0.1:2972/run/podman/podman.sock
+Default:  true
+```
+
+### Container Status
+Podman is operational with 3 containers:
+- `flyer-dev` (Ubuntu) - Exited
+- `flyer-crawler-redis` (Redis) - Exited
+- `flyer-crawler-postgres` (PostGIS) - Exited
+
+## Test Results
+
+### Command Line Tests
+✅ **Podman CLI**: Working - `podman ps` returns successfully
+✅ **Container Management**: Working - Can list and manage containers
+✅ **Socket Connection**: Working - SSH connection to Podman machine functional
+
+### MCP Server Integration Tests
+✅ **Configuration File**: Updated and valid JSON
+✅ **VSCode Restart**: Completed to load new MCP configuration
+✅ **Package Selection**: Using `docker-mcp` (supports SSH connections)
+✅ **Environment Variables**: DOCKER_HOST set correctly for Podman
+
+## How to Verify MCP Server is Working
+
+The Podman MCP server should now be available through Claude Code. To verify:
+
+1. **In Claude Code conversation**: Ask Claude to list containers or perform container operations
+2. **Check VSCode logs**: Look for MCP server connection logs
+3. **Test with MCP Inspector** (optional):
+   ```powershell
+   $env:DOCKER_HOST="ssh://root@127.0.0.1:2972/run/podman/podman.sock"
+   npx -y @modelcontextprotocol/inspector docker-mcp
+   ```
+
+## Expected MCP Tools Available
+
+Once the MCP server is fully loaded, the following tools should be available:
+
+- **Container Operations**: list, start, stop, restart, remove containers
+- **Container Logs**: view container logs
+- **Container Stats**: monitor container resource usage
+- **Image Management**: list, pull, remove images
+- **Container Execution**: execute commands inside containers
+
+## Troubleshooting
+
+### If MCP Server Doesn't Connect
+
+1. **Verify Podman is running**:
+   ```bash
+   podman ps
+   ```
+
+2. **Check SSH connection**:
+   ```bash
+   podman system connection list
+   ```
+
+3. **Test docker-mcp package manually**:
+   ```powershell
+   $env:DOCKER_HOST="ssh://root@127.0.0.1:2972/run/podman/podman.sock"
+   npx -y docker-mcp
+   ```
+
+4. **Check VSCode Extension Host logs**:
+   - Open Command Palette (Ctrl+Shift+P)
+   - Search for "Developer: Show Logs"
+   - Select "Extension Host"
+
+### Common Issues
+
+- **Port 2972 not accessible**: Restart Podman machine with `podman machine restart`
+- **SSH key issues**: Verify SSH keys are set up correctly for Podman machine
+- **Package not found**: Ensure npm can access registry (check internet connection)
+
+## Next Steps
+
+1. Test the Podman MCP server by requesting container operations through Claude Code
+2. If the MCP server isn't responding, check the Extension Host logs in VSCode
+3. Consider testing with alternative packages if `docker-mcp` has issues:
+   - `docker-mcp-server` (alternative community package)
+   - `docker-mcp-secure` (security-focused alternative)
+
+## Additional Notes
+
+- The `docker-mcp` package is a community-maintained MCP server
+- It supports both local Docker sockets and remote SSH connections
+- The package uses the `dockerode` library under the hood, which works with both Docker and Podman
+- Podman's API is Docker-compatible, so Docker MCP servers work with Podman
