Overview

mcp-graphql is a Model Context Protocol server that enables large language models (LLMs) to interact with GraphQL APIs. It provides schema introspection and query execution capabilities, allowing models to discover and use GraphQL APIs dynamically. The server can be configured with environment variables such as ENDPOINT, HEADERS, ALLOW_MUTATIONS, NAME, and SCHEMA. It supports basic usage with a local GraphQL server, custom headers, mutation operations, and using a local schema file or a schema file hosted at a URL. The server exposes the GraphQL schema as a resource and provides tools for introspecting the schema and executing GraphQL queries.
