The GraphQL Schema MCP server enables AI models to explore and understand GraphQL schemas through specialized tools. Built using the Model Context Protocol SDK, it loads any GraphQL schema file and provides tools for exploring query, mutation, and subscription fields, looking up detailed type definitions, searching for types and fields using pattern matching, and getting simplified field information. This implementation is particularly valuable for developers working with GraphQL APIs who need AI assistance in understanding schema structure, exploring available operations, or searching for specific functionality within complex GraphQL schemas.
