ci: Bump version to 0.10.0 for production release [skip ci]

Allows test environment PM2 processes to load environment variables
from /var/www/flyer-crawler-test.projectium.com/.env file, enabling
manual restarts without requiring CI/CD to inject variables.

+# Claude Code MCP Configuration Guide
+
+This document explains how to configure MCP (Model Context Protocol) servers for Claude Code, covering both the CLI and VS Code extension.
+
+## The Two Config Files
+
+Claude Code uses **two separate configuration files** for MCP servers. They must be kept in sync manually.
+
+| File                      | Used By                       | Notes                                       |
+| ------------------------- | ----------------------------- | ------------------------------------------- |
+| `~/.claude.json`          | Claude CLI (`claude` command) | Requires `"type": "stdio"` in each server   |
+| `~/.claude/settings.json` | VS Code Extension             | Simpler format, supports `"disabled": true` |
+
+**Important:** Changes to one file do NOT automatically sync to the other!
+
+## File Locations (Windows)
+
+```text
+C:\Users\<username>\.claude.json           # CLI config
+C:\Users\<username>\.claude\settings.json  # VS Code extension config
+```
+
+## Config Format Differences
+
+### VS Code Extension Format (`~/.claude/settings.json`)
+
+```json
+{
+  "mcpServers": {
+    "server-name": {
+      "command": "path/to/executable",
+      "args": ["arg1", "arg2"],
+      "env": {
+        "ENV_VAR": "value"
+      },
+      "disabled": true // Optional - disable without removing
+    }
+  }
+}
+```
+
+### CLI Format (`~/.claude.json`)
+
+The CLI config is a larger file with many settings. The `mcpServers` section is nested within it:
+
+```json
+{
+  "numStartups": 14,
+  "installMethod": "global",
+  // ... other settings ...
+  "mcpServers": {
+    "server-name": {
+      "type": "stdio", // REQUIRED for CLI
+      "command": "path/to/executable",
+      "args": ["arg1", "arg2"],
+      "env": {
+        "ENV_VAR": "value"
+      }
+    }
+  }
+  // ... more settings ...
+}
+```
+
+**Key difference:** CLI format requires `"type": "stdio"` in each server definition.
+
+## Common MCP Server Examples
+
+### Memory (Knowledge Graph)
+
+```json
+// VS Code format
+"memory": {
+  "command": "D:\\nodejs\\npx.cmd",
+  "args": ["-y", "@modelcontextprotocol/server-memory"]
+}
+
+// CLI format
+"memory": {
+  "type": "stdio",
+  "command": "D:\\nodejs\\npx.cmd",
+  "args": ["-y", "@modelcontextprotocol/server-memory"],
+  "env": {}
+}
+```
+
+### Filesystem
+
+```json
+// VS Code format
+"filesystem": {
+  "command": "d:\\nodejs\\node.exe",
+  "args": [
+    "c:\\Users\\<user>\\AppData\\Roaming\\npm\\node_modules\\@modelcontextprotocol\\server-filesystem\\dist\\index.js",
+    "d:\\path\\to\\project"
+  ]
+}
+
+// CLI format
+"filesystem": {
+  "type": "stdio",
+  "command": "d:\\nodejs\\node.exe",
+  "args": [
+    "c:\\Users\\<user>\\AppData\\Roaming\\npm\\node_modules\\@modelcontextprotocol\\server-filesystem\\dist\\index.js",
+    "d:\\path\\to\\project"
+  ],
+  "env": {}
+}
+```
+
+### Podman/Docker
+
+```json
+// VS Code format
+"podman": {
+  "command": "D:\\nodejs\\npx.cmd",
+  "args": ["-y", "podman-mcp-server@latest"],
+  "env": {
+    "DOCKER_HOST": "npipe:////./pipe/podman-machine-default"
+  }
+}
+```
+
+### Gitea
+
+```json
+// VS Code format
+"gitea-myserver": {
+  "command": "d:\\gitea-mcp\\gitea-mcp.exe",
+  "args": ["run", "-t", "stdio"],
+  "env": {
+    "GITEA_HOST": "https://gitea.example.com",
+    "GITEA_ACCESS_TOKEN": "your-token-here"
+  }
+}
+```
+
+### Redis
+
+```json
+// VS Code format
+"redis": {
+  "command": "D:\\nodejs\\npx.cmd",
+  "args": ["-y", "@modelcontextprotocol/server-redis", "redis://localhost:6379"]
+}
+```
+
+### Bugsink (Error Tracking)
+
+**Important:** Bugsink has a different API than Sentry. Use `bugsink-mcp`, NOT `sentry-selfhosted-mcp`.
+
+**Note:** The `bugsink-mcp` npm package is NOT published. You must clone and build from source:
+
+```bash
+# Clone and build bugsink-mcp
+git clone https://github.com/j-shelfwood/bugsink-mcp.git d:\gitea\bugsink-mcp
+cd d:\gitea\bugsink-mcp
+npm install
+npm run build
+```
+
+```json
+// VS Code format (using locally built version)
+"bugsink": {
+  "command": "d:\\nodejs\\node.exe",
+  "args": ["d:\\gitea\\bugsink-mcp\\dist\\index.js"],
+  "env": {
+    "BUGSINK_URL": "https://bugsink.example.com",
+    "BUGSINK_TOKEN": "your-api-token"
+  }
+}
+
+// CLI format
+"bugsink": {
+  "type": "stdio",
+  "command": "d:\\nodejs\\node.exe",
+  "args": ["d:\\gitea\\bugsink-mcp\\dist\\index.js"],
+  "env": {
+    "BUGSINK_URL": "https://bugsink.example.com",
+    "BUGSINK_TOKEN": "your-api-token"
+  }
+}
+```
+
+- GitHub: <https://github.com/j-shelfwood/bugsink-mcp>
+- Get token from Bugsink UI: Settings > API Tokens
+- **Do NOT use npx** - the package is not on npm
+
+### Sentry (Cloud or Self-hosted)
+
+For actual Sentry instances (not Bugsink), use:
+
+```json
+"sentry": {
+  "command": "D:\\nodejs\\npx.cmd",
+  "args": ["-y", "@sentry/mcp-server"],
+  "env": {
+    "SENTRY_AUTH_TOKEN": "your-sentry-token"
+  }
+}
+```
+
+## Troubleshooting
+
+### Server Not Loading
+
+1. **Check both config files** - Make sure the server is defined in both `~/.claude.json` AND `~/.claude/settings.json`
+
+2. **Verify server order** - Servers load sequentially. Broken/slow servers can block others. Put important servers first.
+
+3. **Check for timeout** - Each server has 30 seconds to connect. Slow npx downloads can cause timeouts.
+
+4. **Fully restart VS Code** - Window reload is not enough. Close all VS Code windows and reopen.
+
+### Verifying Configuration
+
+**For CLI:**
+
+```bash
+claude mcp list
+```
+
+**For VS Code:**
+
+1. Open VS Code
+2. View → Output
+3. Select "Claude" from the dropdown
+4. Look for MCP server connection logs
+
+### Common Errors
+
+| Error                                | Cause                         | Solution                                                                    |
+| ------------------------------------ | ----------------------------- | --------------------------------------------------------------------------- |
+| `Connection timed out after 30000ms` | Server took too long to start | Move server earlier in config, or use pre-installed packages instead of npx |
+| `npm error 404 Not Found`            | Package doesn't exist         | Check package name spelling                                                 |
+| `The system cannot find the path`    | Wrong executable path         | Verify the command path exists                                              |
+| `Connection closed`                  | Server crashed on startup     | Check server logs, verify environment variables                             |
+
+### Disabling Problem Servers
+
+In `~/.claude/settings.json`, add `"disabled": true`:
+
+```json
+"problem-server": {
+  "command": "...",
+  "args": ["..."],
+  "disabled": true
+}
+```
+
+**Note:** The CLI config (`~/.claude.json`) does not support the `disabled` flag. You must remove the server entirely from that file.
+
+## Adding a New MCP Server
+
+1. **Install/clone the MCP server** (if not using npx)
+
+2. **Add to VS Code config** (`~/.claude/settings.json`):
+
+   ```json
+   "new-server": {
+     "command": "path/to/command",
+     "args": ["arg1", "arg2"],
+     "env": { "VAR": "value" }
+   }
+   ```
+
+3. **Add to CLI config** (`~/.claude.json`) - find the `mcpServers` section:
+
+   ```json
+   "new-server": {
+     "type": "stdio",
+     "command": "path/to/command",
+     "args": ["arg1", "arg2"],
+     "env": { "VAR": "value" }
+   }
+   ```
+
+4. **Fully restart VS Code**
+
+5. **Verify with `claude mcp list`**
+
+## Quick Reference: Available MCP Servers
+
+| Server              | Package/Repo                                       | Purpose                     |
+| ------------------- | -------------------------------------------------- | --------------------------- |
+| memory              | `@modelcontextprotocol/server-memory`              | Knowledge graph persistence |
+| filesystem          | `@modelcontextprotocol/server-filesystem`          | File system access          |
+| redis               | `@modelcontextprotocol/server-redis`               | Redis cache inspection      |
+| postgres            | `@modelcontextprotocol/server-postgres`            | PostgreSQL queries          |
+| sequential-thinking | `@modelcontextprotocol/server-sequential-thinking` | Step-by-step reasoning      |
+| podman              | `podman-mcp-server`                                | Container management        |
+| gitea               | `gitea-mcp` (binary)                               | Gitea API access            |
+| bugsink             | `j-shelfwood/bugsink-mcp` (build from source)      | Error tracking for Bugsink  |
+| sentry              | `@sentry/mcp-server`                               | Error tracking for Sentry   |
+| playwright          | `@anthropics/mcp-server-playwright`                | Browser automation          |
+
+## Best Practices
+
+1. **Keep configs in sync** - When you change one file, update the other
+
+2. **Order servers by importance** - Put essential servers (memory, filesystem) first
+
+3. **Disable instead of delete** - Use `"disabled": true` in settings.json to troubleshoot
+
+4. **Use node.exe directly** - For faster startup, install packages globally and use `node.exe` instead of `npx`
+
+5. **Store sensitive data in memory** - Use the memory MCP to store API tokens and config for future sessions
+

+
+## Future: MCP Launchpad
+
+**Project:** <https://github.com/kenneth-liao/mcp-launchpad>
+
+MCP Launchpad is a CLI tool that wraps multiple MCP servers into a single interface. Worth revisiting when:
+
+- [ ] Windows support is stable (currently experimental)
+- [ ] Available as an MCP server itself (currently Bash-based)
+
+**Why it's interesting:**
+
+| Benefit                | Description                                                    |
+| ---------------------- | -------------------------------------------------------------- |
+| Single config file     | No more syncing `~/.claude.json` and `~/.claude/settings.json` |
+| Project-level configs  | Drop `mcp.json` in any project for instant MCP setup           |
+| Context window savings | One MCP server in context instead of 10+, reducing token usage |
+| Persistent daemon      | Keeps server connections alive for faster repeated calls       |
+| Tool search            | Find tools across all servers with `mcpl search`               |
+
+**Current limitations:**
+
+- Experimental Windows support
+- Requires Python 3.13+ and uv
+- Claude calls tools via Bash instead of native MCP integration
+- Different mental model (runtime discovery vs startup loading)
+
+---
+
+## Future: Graphiti (Advanced Knowledge Graph)
+
+**Project:** <https://github.com/getzep/graphiti>
+
+Graphiti provides temporal-aware knowledge graphs - it tracks not just facts, but _when_ they became true/outdated. Much more powerful than simple memory MCP, but requires significant infrastructure.
+
+**Ideal setup:** Run on a Linux server, connect via HTTP from Windows:
+
+```json
+// Windows client config (settings.json)
+"graphiti": {
+  "type": "sse",
+  "url": "http://linux-server:8000/mcp/"
+}
+```
+
+**Linux server setup:**
+
+```bash
+git clone https://github.com/getzep/graphiti.git
+cd graphiti/mcp_server
+docker compose up -d  # Starts FalkorDB + MCP server on port 8000
+```
+
+**Requirements:**
+
+- Docker on Linux server
+- OpenAI API key (for embeddings)
+- Port 8000 open on LAN
+
+**Benefits of remote deployment:**
+
+- Heavy lifting (Neo4j/FalkorDB + embeddings) offloaded to Linux
+- Always-on server, Windows connects/disconnects freely
+- Multiple machines can share the same knowledge graph
+- Avoids Windows Docker/WSL2 complexity

 # Claude Code Project Instructions
 
+## Session Startup Checklist
+
+**IMPORTANT**: At the start of every session, perform these steps:
+
+1. **Check Memory First** - Use `mcp__memory__read_graph` or `mcp__memory__search_nodes` to recall:
+   - Project-specific configurations and credentials
+   - Previous work context and decisions
+   - Infrastructure details (URLs, ports, access patterns)
+   - Known issues and their solutions
+
+2. **Review Recent Git History** - Check `git log --oneline -10` to understand recent changes
+
+3. **Check Container Status** - Use `mcp__podman__container_list` to see what's running
+
+---
+
+## Project Instructions
+
+### Things to Remember
+
+Before writing any code:
+
+1. State how you will verify this change works (test, bash command, browser check, etc.)
+
+2. Write the test or verification step first
+
+3. Then implement the code
+
+4. Run verification and iterate until it passes

+### Database User Setup (Test Environment)
+
+**CRITICAL**: The test database requires specific PostgreSQL permissions to be configured manually. Schema ownership alone is NOT sufficient - explicit privileges must be granted.

+| -------------------- | -------------------- | ---------- |
+| `flyer_crawler_prod` | `flyer-crawler`      | Production |
+| `flyer_crawler_test` | `flyer-crawler-test` | Testing    |
+
+**Required Setup Commands** (run as `postgres` superuser):
+
+```bash
+# Connect as postgres superuser
+sudo -u postgres psql
+
+# Create the test database and user (if not exists)
+CREATE DATABASE "flyer-crawler-test";
+CREATE USER flyer_crawler_test WITH PASSWORD 'your-password-here';
+
+# Grant ownership and privileges
+ALTER DATABASE "flyer-crawler-test" OWNER TO flyer_crawler_test;
+\c "flyer-crawler-test"
+ALTER SCHEMA public OWNER TO flyer_crawler_test;
+GRANT CREATE, USAGE ON SCHEMA public TO flyer_crawler_test;
+
+# Create required extension (must be done by superuser)
+CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
+```
+
+**Why These Steps Are Necessary:**
+
+1. **Schema ownership alone is insufficient** - PostgreSQL requires explicit `GRANT CREATE, USAGE` privileges even when the user owns the schema
+2. **uuid-ossp extension** - Required by the application for UUID generation; must be created by a superuser before the app can use it
+3. **Separate users for prod/test** - Prevents accidental cross-environment data access; each environment has its own credentials in Gitea secrets
+
+**Verification:**
+
+```bash
+# Check schema privileges (should show 'UC' for flyer_crawler_test)
+psql -d "flyer-crawler-test" -c "\dn+ public"

-### Step 2: Configure Application to Write File Logs
+### Step 2: Application File Logging (Already Configured)
 
-The flyer-crawler application uses Pino for logging and currently outputs to stdout (captured by PM2). To enable file-based logging for Logstash, you would need to configure Pino to write to files.
+The flyer-crawler application uses Pino for logging and is configured to write logs to files in production/test environments:
 
-**Current Behavior:** Logs go to stdout → PM2 captures them → `~/.pm2/logs/`
+**Log File Locations:**
 
-**For Logstash Integration:** You would need to either:
+| Environment   | Log File Path                                             |
+| ------------- | --------------------------------------------------------- |

+| Dev Container | `/app/logs/app.log`                                       |
 
-1. Configure Pino to write directly to files (requires code changes)
-2. Use PM2's log files instead (located at `~/.pm2/logs/flyer-crawler-*.log`)
+**How It Works:**
 
-For now, we'll use PM2's log files which already exist:
+- In production/test: Pino writes JSON logs to both stdout (for PM2) AND `logs/app.log` (for Logstash)
+- In development: Pino uses pino-pretty for human-readable console output only
+- The log directory is created automatically if it doesn't exist
+- You can override the log directory with the `LOG_DIR` environment variable
+
+**Verify Logging After Deployment:**
+
+After deploying the application, verify that logs are being written:
 
 ```bash
-# Check PM2 log location
-ls -la ~/.pm2/logs/
+# Check production logs
+ls -la /var/www/flyer-crawler.projectium.com/logs/
+tail -f /var/www/flyer-crawler.projectium.com/logs/app.log
+
+# Check test logs
+ls -la /var/www/flyer-crawler-test.projectium.com/logs/
+tail -f /var/www/flyer-crawler-test.projectium.com/logs/app.log
+```
+
+You should see JSON-formatted log entries like:

+What is the correct named pipe address for Podman on Windows if it's not using the default docker_engine pipe?
+
+How do I configure the chrome-devtools-mcp server to connect to an existing Chrome instance using the browser_url input?
+
+
+Unused Input: The browser_url input is defined but not used in any server arguments. If you intend to connect chrome-devtools-mcp to an existing Chrome instance, you would typically pass that URL in the arguments instead of launching a new headless instance.
+
+
+
+
+
+Based on your current configuration and project setup (Gitea, Podman, PostgreSQL, Redis), here are several other valuable MCP servers available for VS Code.
+
+Recommended for Your Stack
+Since you are running a PostgreSQL and Redis stack via Podman, these servers would be immediately useful:
+
+PostgreSQL (@modelcontextprotocol/server-postgres)
+
+Purpose: Allows the AI to query your database directly (inspect schemas, run SELECT queries) without needing to shell into the container.
+Config:
+json
+"postgres": {
+  "command": "npx",
+  "args": ["-y", "@modelcontextprotocol/server-postgres", "postgresql://postgres:postgres@localhost:5432/flyer_crawler_dev"]
+}
+
+
+
+Redis (@modelcontextprotocol/server-redis)
+
+Purpose: Inspect and modify keys in your Redis instance.
+Config:
+json
+"redis": {
+  "command": "npx",
+  "args": ["-y", "@modelcontextprotocol/server-redis", "redis://localhost:6379"]
+}
+General Utility Servers
+These servers enhance the AI's core capabilities regardless of the specific project:
+
+
+Memory (@modelcontextprotocol/server-memory)
+
+Purpose: Gives the AI a persistent "knowledge graph" to remember context, user preferences, and project details across different chat sessions.
+Config:
+json
+"memory": {
+  "command": "npx",
+  "args": ["-y", "@modelcontextprotocol/server-memory"]
+}
+
+
+Brave Search (@modelcontextprotocol/server-brave-search)
+
+Purpose: Performs actual web searches (finding current docs, libraries, or solutions) rather than just fetching specific URLs like the fetch server does.
+Config:
+json
+ Show full code block 
+"brave-search": {
+  "command": "npx",
+  "args": ["-y", "@modelcontextprotocol/server-brave-search"],
+  "env": {
+    "BRAVE_API_KEY": "YOUR_API_KEY_HERE"
+  }
+}
+
+
+Sequential Thinking (@modelcontextprotocol/server-sequential-thinking)
+
+Purpose: A tool that helps the AI break down complex problems into step-by-step thought processes. It is particularly useful for debugging difficult logic or architectural planning.
+Config:
+json
+"sequential-thinking": {
+  "command": "npx",
+  "args": ["-y", "@modelcontextprotocol/server-sequential-thinking"]
+}
+
+
+Other Popular Servers
+
+GitHub: (@modelcontextprotocol/server-github) - If you ever need to interact with GitHub.com in addition to Gitea.
+
+Google Drive: (@modelcontextprotocol/server-google-drive) - Access files in Google Drive.
+
+Slack: (@modelcontextprotocol/server-slack) - Read and send Slack messages.
+
+Sentry: (@modelcontextprotocol/server-sentry) - Analyze error reports directly from Sentry.
+
+How to Find More
+The community maintains a comprehensive list of servers in the Awesome MCP Servers repository. You can find servers for almost any major tool (AWS, Azure, Linear, Jira, etc.).
+
+To add any of these, you simply add a new entry to the mcpServers object in your mcp.json file, similar to how you configured podman or fetch.
+
+
+
+
+
+
+Create a new ADR for "Worker Health Checks" to monitor stalled background jobs.
