Mcp Graphql Enhanced

letoribo/mcp-graphql-enhanced

This is a production-grade GraphQL gateway that solves the context window problem when introspecting large schemas like GitHub's or Neo4j's. It adds scoped introspection via typeNames and typeDepth parameters, so you can selectively load only the types you need instead of dumping the entire schema and hitting MCP's size limits. The federated mode lets you query multiple GraphQL endpoints as a single unified graph, which is useful for bridging WSL and Windows services or splitting data across free-tier database instances. It includes dynamic header injection for authentication, a built-in GraphiQL IDE for testing queries, and automatic Cypher extraction from Neo4j responses. Mutations are disabled by default.
