MCP GraphQL Server
Mcp Graphql enables LLMs to interact with GraphQL APIs by providing schema introspection and query execution capabilities. The server offers two main tools: introspect-schema for retrieving GraphQL schemas from local files, URLs, or introspection queries, and query-graphql for executing GraphQL queries against a specified endpoint. It solves the problem of allowing language models to dynamically discover and use GraphQL APIs without hardcoded knowledge of their structure.
