unraid-mcp

An MCP (Model Context Protocol) server that enables AI assistants like Claude to manage Unraid servers through natural language. Install it once from Community Applications and control your homelab from any MCP-compatible AI client.

61 tools across 8 categories:

Example interactions:

• "Show me all running Docker containers and their memory usage"
• "Stop the Plex container, wait 10 seconds, then start it again"
• "What's the health of my array disks? Any temperatures I should worry about?"
• "List all VMs and tell me which ones are using the most memory"

  unraid-mcp server  ← binary compiled with bun, runs as Unraid plugin
        │
        ├── GraphQL API (port 31337, Unraid 7.2+) ← primary
        └── CLI / file parsing                     ← fallback

GraphQL-first: Unraid 7.2 introduced a GraphQL API on port 31337. All tools use it as the primary backend for reliability and type safety.

CLI fallback: For operations not yet in the GraphQL API, tools fall back to parsing /proc files, running docker CLI commands, or reading Unraid config files directly.

Compiled binary: The server is compiled to a standalone executable with bun compile — no Node.js or npm required on the Unraid host.

1. Open Community Applications in your Unraid UI
2. Search for "Unraid MCP"
3. Click Install
4. Go to Settings → Unraid MCP to configure your API key and port

Download the latest .plg file and install via Plugins → Install Plugin in your Unraid UI.

After installation, configure via Settings → Unraid MCP in the Unraid UI:

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "unraid": {
      "url": "http://YOUR_UNRAID_IP:3000/mcp"
    }
  }
}

Replace YOUR_UNRAID_IP with your Unraid server's IP address.

Contributions welcome! Areas that need work:

• More tools: The Unraid GraphQL API has many more operations — PRs adding tools are very welcome
• CLI fallbacks: Improve fallbacks for Unraid versions below 7.2
• Testing: Integration tests against a real or mocked Unraid API
• Documentation: Better examples and use cases

1. Find the relevant tool category under src/tools/
2. Add a new server.tool(...) call following the existing pattern
3. Define the GraphQL query/mutation as a constant
4. Add TypeScript types to src/types/index.ts if needed
5. Submit a PR with a description of the tool and the GraphQL operation it uses

Please open an issue at https://github.com/lherron/unraid-mcp/issues with:
