Architecture

  • Node.js (ESM), Express, @modelcontextprotocol/sdk.

  • Transport: Streamable HTTP, stateless (a fresh MCP server + transport per request).

  • The same Node process serves the static landing page and docs, plus the /mcp endpoint.

  • Deployed behind nginx with Let's Encrypt TLS and kept alive by PM2.
