MCP Servers

This project sets up Model Context Protocol (MCP) servers using Docker Compose.

Included Servers

  • Git - Read, search, and manipulate Git repositories
  • Filesystem - Secure file operations with configurable access controls
  • PostgreSQL - Database access with schema inspection
  • Memory - Knowledge graph-based persistent memory system
  • Inspector - GUI tool for managing and debugging MCP servers (run locally with npx)

Setup

  1. Initialize the repository:
./scripts/init-repo.sh

This will:

  • Set the correct Node.js version using nvm
  • Install MCP Inspector globally
  1. Start the containerized servers:
docker compose up -d
  1. Start the MCP Inspector locally:
./scripts/start-inspector.sh
  1. Stop the MCP Inspector:
./scripts/stop-inspector.sh
  1. Stop the containerized servers:
docker compose down

Directory Structure

  • docker-data/ - Data directories for each MCP server
  • docker-files/ - Dockerfile resources
  • scripts/ - Utility scripts for managing services
    • init-repo.sh - Initialize the repository with correct Node.js and packages
    • start-inspector.sh - Start the MCP Inspector in background
    • stop-inspector.sh - Stop the MCP Inspector
    • templates:
    • template-start-mcp-server.sh - Template for creating start scripts for MCP servers
    • template-stop-mcp-server.sh - Template for creating stop scripts for MCP servers

Configuration

Each server can be configured through environment variables in the docker-compose.yml file.

Accessing the Inspector

The MCP Inspector will be available at http://localhost:5173 after starting it with the script.

Logs

  • Inspector logs are stored in ./docker-data/inspector/inspector.log

Adding New MCP Servers

To add a new MCP server that runs locally (non-dockerized):

  1. Copy the template scripts:
cp scripts/template-start-mcp-server.sh scripts/start-newserver.sh
cp scripts/template-stop-mcp-server.sh scripts/stop-newserver.sh
chmod +x scripts/start-newserver.sh scripts/stop-newserver.sh
  1. Edit both scripts to set:
  • SERVER_NAME - Name of your server
  • NPX_COMMAND - NPX command to run the server
  • PORT - Port the server runs on
  1. Make sure to install the server package globally or specify it in the NPX command.
