GraphQL Enhanced is an advanced Model Context Protocol (MCP) server designed to overcome real-world interoperability challenges when connecting Large Language Models (LLMs) with GraphQL APIs. It serves as a drop-in replacement for `mcp-graphql`, offering crucial enhancements such as dynamic header support for authentication, robust parsing of query variables, and the ability to perform filtered schema introspection to reduce LLM context noise. This ensures full compatibility with various MCP clients like Claude Desktop, Cursor, Glama, and Smithery, while prioritizing security by disabling mutations by default.
