Simplifying MCP Tool Sprawl With GraphQL
summary
Claims GraphQL can act as a single MCP layer to stop per-backend tool bloat and the team proves it by building an SDK that introspects GraphQL, exposes a single MCP endpoint, and optionally turns subsets into named tools via schema annotations or into planner endpoints using persisted documents. Tests show small models (Granite ~3B) reach ~90% accuracy with schema comments and examples, and modern LLMs remove the need to replicate or heavily trim large schemas.
