MCP Hub 中国 provides a curated collection of MCP services packaged as individual servers within a single monorepo. The repository includes a file-operations server and a weather-api server, among others, designed to demonstrate common MCP patterns such as file handling and external API access. To get started, clone the repository, install dependencies, and start the development environment. You can run the servers locally and access their endpoints to test MCP interactions, or integrate these services into your own MCP hub setup. The included CLI and web UI help manage and discover MCP services, and you can leverage the provided commands to install, link, or generate deep links for MCP services you wish to use in Cursor or other clients.

Prerequisites:

• Git
• Node.js (LTS) and npm or pnpm
• Internet access to install dependencies

1. Clone the repository

git clone https://github.com/mengjian-github/mcp-cn.git cd mcp-cn

2. Install dependencies

If you have pnpm installed

pnpm install

If you prefer npm

npm install

3. Run the development servers

Start both servers in parallel (example commands)

pnpm run dev

Or start individually (if you prefer)

node packages/servers/file-operations/index.js node packages/servers/weather-api/index.js

4. Open the web UI (if running via the hosted web app)

http://localhost:7777

Notes:

• The server entry points are located under packages/servers. Each server exposes its own HTTP/API endpoints.
• If you customize ports, ensure they do not conflict with other services in your environment.

Tips and common issues:

• Ensure Node.js version compatibility with the server entry files.
• If ports are in use, change the PORT in the respective server's environment variables or args.
• For API keys (e.g., weather API), set OPEN_WEATHER_API_KEY or any required API token in env vars.
• While developing, use pnpm for faster installs in monorepos; otherwise npm works as well.
• The mcp_config allows you to add more MCP servers by following the same structure as file-operations and weather-api; simply point to the new server's entry script and define any needed environment variables.

Environment variables overview:

• PORT: TCP port the server will listen on
• For weather-api: OPEN_WEATHER_API_KEY or other provider credentials
• LOG_LEVEL: info, warn, error for logging verbosity
