What is the MCP Server?

Bridges any GraphQL API to Claude Code — auto-generates MCP tools via schema introspection.

What you get

A generic MCP (Model Context Protocol) server that bridges any GraphQL API to Claude Code. It introspects your GraphQL schema and exposes each query and mutation as an individual tool, letting Claude interact with your API directly.

What the assistant can call

Once MCP is connected, these are the calls the assistant has available:

  • execute_graphql — Generic fallback — run any query or mutation (mutations rejected if GRAPHQL_INCLUDE_MUTATIONS=false)
  • get_type_details — Explore fields of a specific GraphQL type

Configuration and credentials

  • Node.js >= 20

Recorded tools

Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
