MCP GraphQL

Example Use Cases

• 1

  Call specific GraphQL queries and receive structured JSON results without implementing a GraphQL client.

• 2

  Quickly explore or prototype against a GraphQL API by auto-generating queries from schema introspection (with configurable max depth).

• 3

  Authenticated access to GraphQL endpoints using Bearer, Basic, or custom header-based authentication while mapping query parameters to JSON schema.

Description

MCP GraphQL introspects a GraphQL endpoint and automatically creates an MCP tool for each named query, generating JSON schemas for tool inputs from GraphQL parameters. It handles authentication (Bearer, Basic, custom headers), complex types, and can auto-generate exploratory queries up to a configurable depth. This enables MCP-compatible clients and agents to interact with GraphQL services without writing GraphQL client code, while also allowing users to supply precise queries for production use.
