GitHub-Powered MCP Documentation Servers

Sometimes you don’t write the docs yourself – you simply want the full, up‑to‑date documentation of an open‑source library on GitHub available to your AI assistant. The community projects below turn any repository into a remote MCP server that streams documentation on demand.

Context7

Context7 automatically ingests popular open‑source libraries (and many private ones too) and exposes them as remote MCP servers.

{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": ["-y", "@upstash/context7-mcp@latest"]
    }
  }
}

{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": ["-y", "@upstash/context7-mcp@latest"]
    }
  }
}

{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": ["-y", "@upstash/context7-mcp@latest"]
    }
  }
}

{
    "mcpServers": {
        "context7": {
            "command": "npx",
            "args": ["-y", "@upstash/context7-mcp@latest"],
            "disabled": false,
            "autoApprove": []
        }
    }
}

{
    "servers": {
        "Context7": {
            "type": "stdio",
            "command": "npx",
            "args": ["-y", "@upstash/context7-mcp@latest"]
        }
    }
}

Example: Using Context7 with Three.js

After installing Context7, you can prompt your AI assistant to use Three.js documentation like this:

Can you help me create a basic Three.js scene with a rotating cube?
Use context7

The AI will then dynamically query Context7 for relevant Three.js documentation as it helps you.

​

GitMCP.io

GitMCP lets you turn any public GitHub repository into a fully‑featured MCP server just by changing the domain from github.com → gitmcp.io (or github.io → gitmcp.io). No build step, no package installs.

{
  "mcpServers": {
    "threejs": {
      "url": "https://gitmcp.io/mrdoob/three.js"
    }
  }
}

{
  "mcpServers": {
    "threejs": {
      "url": "https://gitmcp.io/mrdoob/three.js"
    }
  }
}

{
  "mcpServers": {
    "threejs": {
      "serverUrl": "https://gitmcp.io/mrdoob/three.js"
    }
  }
}

{
      "mcpServers": {
          "threejs": {
              "url": "https://gitmcp.io/mrdoob/three.js",
              "disabled": false,
              "autoApprove": []
          }
      }
  }
}

{
  "servers": {
    "threejs": {
      "type": "sse",
      "url": "https://gitmcp.io/mrdoob/three.js"
    }
  }
}

Example: Three.js Documentation

Once either MCP server is configured, the following single‑shot prompt in Cursor + Claude illustrates the improvement:

Build a Three.js scene featuring a controllable realistic person navigating a textured dynamic urban environment with realistic lighting and subtle bloom effects. Ensure keyboard controls (WASD) for movement.
