ChatGPT MCP Server

A Model Context Protocol (MCP) server that provides Docker management capabilities through a custom GPT interface.

Features

• Docker container management through natural language
• Built on the Model Context Protocol (MCP)
• TypeScript implementation
• Containerized deployment
• Robust error handling and graceful shutdown
• Resource management and port handling
• Rate limiting and API key authentication

Setup

Installing via Smithery

To install ChatGPT MCP Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @Toowiredd/chatgpt-mcp-server --client claude

Manual Installation

1. Clone the repository

git clone https://github.com/toowiredd/chatgpt-mcp-server.git
cd chatgpt-mcp-server

2. Install dependencies

npm install

3. Create environment file

cp env.example .env
# Edit .env with your configuration

4. Build the project

npm run build

Running with Docker

1. Build the container

npm run docker:build

2. Run the container

npm run docker:run

Or manually:

docker run -d \
  -p 3001:3001 \
  --env-file .env \
  -v /var/run/docker.sock:/var/run/docker.sock \
  chatgpt-mcp-server

Development

• `npm run build` - Build the TypeScript code
• `npm run watch` - Watch for changes and rebuild
• `npm run inspector` - Run the MCP inspector tool

Environment Variables

• `API_KEY` - API authentication key
• `HTTP_PORT` - Server port (default: 3001)
• `RATE_LIMIT_REQUESTS` - Maximum requests per window
• `RATE_LIMIT_WINDOW` - Window size in milliseconds

Resource Management

The server implements robust resource management:

• Graceful shutdown on process signals (SIGINT, SIGTERM, SIGQUIT)
• Connection tracking and management
• Request timeout handling
• Port conflict detection
• Keep-alive connection management
• Active request tracking and graceful completion

Shutdown Process

1. The server initiates graceful shutdown on process signals

2. New connections are rejected

3. Active requests are allowed to complete (with timeout)

4. Keep-alive connections are closed

5. Server ports are properly released

6. Resources are properly released

Error Handling

• Port conflicts are detected and reported
• Unhandled rejections and exceptions are caught
• Network errors are properly handled
• Resource leaks are prevented through proper handling
• Timeouts ensure the server doesn't hang during shutdown
