Description

This MCP server provides schema introspection and query execution for GraphQL APIs, exposing the schema as a resource and offering tools for introspecting and running queries. It supports using a local schema file or performing an introspection query against a provided endpoint, and can be configured with custom headers and optional mutation support. Mutations are disabled by default as a security measure, and the server is installable via Smithery or run directly with provided CLI options. It's useful for enabling LLMs to dynamically explore and interact with GraphQL services.
