Unraid MCP

MCP server for Unraid NAS management. Exposes a unified unraid action router with 15 action domains and 107 subactions, plus unraid_help and two diagnostic tools, all backed by Unraid's GraphQL API and real-time WebSocket subscriptions.

Overview

Four MCP tools are exposed:

Tool	Purpose
unraid	Unified action router for all Unraid operations (15 domains, 107 subactions)
unraid_help	Returns markdown documentation for all actions and parameters
diagnose_subscriptions	Inspect WebSocket subscription connection states and errors
test_subscription_query	Test a specific GraphQL subscription query against allowlisted fields

The server supports streamable-http (default), SSE (deprecated), and stdio transports. HTTP transports require RFC 6750 bearer authentication via UNRAID_MCP_BEARER_TOKEN.

What this repository ships

• unraid_mcp/server.py: FastMCP server with 4-layer middleware chain and ASGI bearer auth
• unraid_mcp/tools/: 16 domain modules (array, customization, disk, docker, health, key, live, notification, oidc, plugin, rclone, setting, system, user, vm) plus the consolidated unraid.py router
• unraid_mcp/subscriptions/: WebSocket subscription manager, resource registration, diagnostics, and snapshot queries
• unraid_mcp/core/: GraphQL client, elicitation-based setup, destructive action guards, auth middleware
• unraid_mcp/config/: Settings management and structured logging
• skills/unraid/SKILL.md: Client-facing skill documentation
• .claude-plugin/plugin.json, .codex-plugin/plugin.json, gemini-extension.json: Client manifests
• docker-compose.yaml, Dockerfile, entrypoint.sh: Container deployment
• scripts/: Security checks, dependency audits, and plugin validation
• hooks/: Post-tool hooks for env permissions and gitignore enforcement

Installation

Marketplace

/plugin marketplace add jmagar/claude-homelab
/plugin install unraid-mcp @jmagar-claude-homelab

Local development

uv sync --dev
uv run unraid-mcp-server

Docker

just up

Or manually:

docker compose up -d

Authentication

The MCP server uses bearer token authentication for HTTP transports (streamable-http, SSE).

A token is auto-generated on first HTTP startup if none is configured. It is written to ~/.unraid-mcp/.env.

To generate manually:

openssl rand -hex 32

Set it in ~/.unraid-mcp/.env:

UNRAID_MCP_BEARER_TOKEN=<generated-token>

Configure your MCP client to send the token as a Bearer header. See AUTH for detailed setup.

To disable auth (only behind a trusted reverse proxy):

UNRAID_MCP_DISABLE_HTTP_AUTH=true

Configuration

Copy .env.example to ~/.unraid-mcp/.env and fill in the required values:

mkdir -p ~/.unraid-mcp
cp .env.example ~/.unraid-mcp/.env
chmod 600 ~/.unraid-mcp/.env

Or use the interactive setup wizard:

unraid(action="health", subaction="setup")

Environment variables

Variable	Required	Default	Description
UNRAID_API_URL	yes	--	Unraid GraphQL endpoint (e.g. https://tower.local/graphql)
UNRAID_API_KEY	yes	--	Unraid API key (Settings > Management Access > API Keys)
UNRAID_MCP_BEARER_TOKEN	yes*	auto-generated	Bearer token for MCP HTTP auth
UNRAID_MCP_PORT	no	6970	Port for the MCP HTTP server

*Required when UNRAID_MCP_TRANSPORT != stdio and UNRAID_MCP_DISABLE_HTTP_AUTH != true.

See CONFIG for all variables including logging, SSL, subscriptions, and Docker settings.

Quick start

# First-time setup
unraid(action="health", subaction="setup")

# System overview
unraid(action="system", subaction="overview")

# Health check
unraid(action="health", subaction="check")

# List Docker containers
unraid(action="docker", subaction="list")

# Restart a container
unraid(action="docker", subaction="restart", container_id="plex")

# Parity status
unraid(action="array", subaction="parity_status")

# Live CPU monitoring
unraid(action="live", subaction="cpu")

# Stop array (destructive)
unraid(action="array", subaction="stop_array", confirm=True)

Docker usage

# Build and start
just up

# View logs
just logs

# Health check
just health
# or: curl http://localhost:6970/health

# Stop
just down

The /health endpoint is unauthenticated for liveness probes.
