GitHub MCP Server (Streamable HTTP, stateless)

TypeScript MCP server that exposes 5 GitHub tools over stateless Streamable HTTP.
No sessions / no mcp-session-id — each POST is independent (good for gateways and multi-instance deploy).
The GitHub access-token header is required only for tools/call.
initialize, tools/list, and other discovery methods work without a token.

Tools

Related MCP server: @cloud9-labs/mcp-github

Requirements

• Node.js 18+

• A GitHub personal access token (classic or fine-grained) with the scopes your tools need

  • Read tools: repo (or public-only fine-grained read)

  • create_issue: issues write on the target repo

Setup

npm install
npm run build
npm start

Dev (no build step):

npm run dev

Docker

docker build -t github-mcp .
docker run --rm -p 3000:3000 github-mcp

MCP endpoint: http://localhost:3000/mcp.

Server listens on http://localhost:3000/mcp (override with PORT).

Authentication

On tool calls, send a GitHub personal access token:

access-token: ghp_your_token_here

Alternatively:

Authorization: Bearer ghp_your_token_here

Missing token on tools/call → 401 JSON-RPC error.

Client configuration

Point any Streamable HTTP MCP client at:

http://localhost:3000/mcp

Send the GitHub token on tool-call requests (many clients set it for all requests to the server):

{
  "mcpServers": {
    "github": {
      "url": "http://localhost:3000/mcp",
      "headers": {
        "access-token": "ghp_your_token_here"
      }
    }
  }
}

(Exact client config shape depends on the client.)

Health check

curl http://localhost:3000/health
