🎯 Claude Code Plugin

The easiest way to use Unraid MCP is through the Claude Code marketplace:

# Add the marketplace
/plugin marketplace add jmagar/unraid-mcp

# Install the Unraid skill
/plugin install unraid @unraid-mcp

This provides instant access to Unraid monitoring and management through Claude Code with:

• 11 MCP tools exposing ~104 actions via the consolidated action pattern
• 10 slash commands for quick CLI-style access (commands/)
• Real-time system metrics and health monitoring
• Docker container and VM lifecycle management
• Disk health monitoring and storage management

See .claude-plugin/README.md for detailed plugin documentation.

⚙️ Credential Setup (Automatic)

On first use, the plugin will automatically prompt you for credentials via an interactive elicitation dialog in Claude Code. Simply call any Unraid tool and follow the prompts — no manual .env configuration needed.

Alternatively, trigger setup explicitly:

unraid_health action=setup

Credentials are saved to .env in the plugin cache directory and persisted across restarts.

Manual fallback: If elicitation is not supported by your client, create .env in the plugin cache directory manually (see .env.example for the format).

Code Quality Commands

# Lint and format code
uv run ruff check unraid_mcp/
uv run ruff format unraid_mcp/

# Type checking
uv run ty check unraid_mcp/

# Run tests
uv run pytest

Integration Smoke-Tests (mcporter)

Live integration tests that exercise all non-destructive actions via mcporter. Two scripts cover two transport modes:

# stdio — no running server needed (good for CI)
./tests/mcporter/test-tools.sh [--parallel] [--timeout-ms N] [--verbose]

# HTTP — connects to a live server (most up-to-date coverage)
./tests/mcporter/test-actions.sh [MCP_URL]   # default: http://localhost:6970/mcp

Destructive actions are always skipped in both scripts. For safe testing strategies and exact mcporter commands per destructive action, see docs/DESTRUCTIVE_ACTIONS.md.

API Schema Docs Automation

# Regenerate complete GraphQL schema reference from live introspection
set -a; source .env; set +a
uv run python scripts/generate_unraid_api_reference.py

This updates docs/UNRAID_API_COMPLETE_REFERENCE.md with all operations, directives, and types visible to your API key.

Optional cron example (daily at 03:15):

15 3 * * * cd /path/to/unraid-mcp && /usr/bin/env bash -lc 'set -a; source .env; set +a; uv run python scripts/generate_unraid_api_reference.py && git add docs/UNRAID_API_COMPLETE_REFERENCE.md && git commit -m "docs: refresh unraid graphql schema"'

Development Workflow

# Start development server
uv run unraid-mcp-server

# Or run via module directly
uv run -m unraid_mcp.main

🏗️ Architecture

Core Principles

• Modular Design: Separate concerns across focused modules
• Async First: All operations are non-blocking and concurrent-safe
• Error Resilience: Comprehensive error handling with graceful degradation
• Configuration Driven: Environment-based configuration with validation
• Observability: Structured logging and health monitoring

Key Components

Component	Purpose
FastMCP Server	MCP protocol implementation and tool registration
GraphQL Client	Async HTTP client with timeout management
Subscription Manager	WebSocket connections for real-time data
Tool Modules	Domain-specific business logic (Docker, VMs, etc.)
Configuration System	Environment loading and validation
Logging Framework	Structured logging with file rotation

🐛 Troubleshooting

Common Issues

🔥 Port Already in Use

# Kill existing process on port 6970, then restart
lsof -ti :6970 | xargs kill -9 2>/dev/null; uv run unraid-mcp-server

🔧 Connection Refused

# Check Unraid API configuration
curl -k "${UNRAID_API_URL}" -H "X-API-Key: ${UNRAID_API_KEY}"

📝 Import Errors

# Reinstall dependencies
uv sync --reinstall

🔍 Debug Mode

# Enable debug logging
export UNRAID_MCP_LOG_LEVEL=DEBUG
uv run unraid-mcp-server

Health Check

# Use the built-in health check tool via MCP client
# or check logs at: logs/unraid-mcp.log
