  -v /path/to/your/project:/workspace:rw \
  mcp-file-git-server

Docker Compose

Add to your docker-compose.yml:

services:
  mcp-server:
    build: ./mcp-file-git-server
    container_name: mcp-file-git-server
    environment:

      - PORT=3001
      - NODE_ENV=production
    ports:

    volumes:
      - /path/to/your/project:/workspace:rw
      - ~/.gitconfig:/root/.gitconfig:ro
      - ~/.ssh:/root/.ssh:ro

      - n8n-traefik_default
    restart: unless-stopped
    healthcheck:
      test: ["CMD", "wget", "-q", "--spider", "http://localhost:3001/health"]
      interval: 30s
      timeout: 10s
      retries: 3

Configuration

Environment Variables

• PORT: Server port (default: 3001)

Endpoints

• Health Check: GET http://localhost:3001/health
• SSE Endpoint: POST http://localhost:3001/sse (for n8n-nodes-mcp)
• Message Endpoint: POST http://localhost:3001/message

Testing

Test Health Endpoint

curl http://localhost:3001/health

curl -X POST http://localhost:3001/sse \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'

Troubleshooting

Permission Denied

Ensure the mounted project directory has correct permissions:

sudo chown -R $(id -u):$(id -g) /path/to/your/project

Git Not Working

Initialize git in the project directory:

docker exec -it mcp-file-git-server sh
cd /workspace
git init
git config user.name "Your Name"
git config user.email "your@email.com"
exit

Connection Issues

Check Docker network connectivity:

# From n8n container
docker exec -it n8n-traefik-n8n-1 sh
wget -O- http://mcp-file-git-server:3001/health
exit
