GraphQL MCP Server

MCPOpen SourceMIT70.5

by blurrah • APIs & Integration

A Model Context Protocol (MCP) server that allows LLM agents to introspect GraphQL schemas and execute queries against GraphQL endpoints.

Example Use Cases

1
Discover a GraphQL API schema automatically via introspection or a provided schema file.
2
Execute read queries (and optionally mutations when enabled) against a GraphQL endpoint with custom headers.
3
Expose the GraphQL schema as a resource so downstream components or models can reference available types and fields.

Description

This MCP server provides automatic GraphQL schema discovery (via introspection or local/remote schema files) and a tool to execute queries against a configured GraphQL endpoint. It supports custom request headers and can optionally enable mutations (disabled by default for safety). The server is designed to let LLMs dynamically discover and interact with GraphQL APIs without manual schema provisioning.
