Grafbase

Grafbase

The Grafbase MCP server represents a breakthrough in AI-powered development, being the first GraphQL Federation platform to offer Model Context Protocol (MCP) support out of the box. This innovative server transforms how AI assistants like ChatGPT and Claude interact with GraphQL APIs by providing intelligent schema exploration and query execution capabilities.

Grafbase provides secure, self-hosted deployment options, unmatched query speed, and unified data access for reliable, enterprise-grade GraphQL API management. The integration of MCP technology makes it the perfect bridge between enterprise GraphQL infrastructure and modern AI development workflows.

Key Capabilities & Value Proposition

Smart Schema Intelligence

The Grafbase MCP server enables agents to interact with large GraphQL schemas without exceeding context limits or relying on brittle hardcoding, delivering the best of both flexibility and performance. The server uses three powerful tools:

🔍 Search Tool: Provides the most relevant subset of the GraphQL schema as SDL, searching for the most relevant fields with lowest depth 📊 Introspect Tool: Requests information on specific types for deep schema exploration ⚡ Execute Tool: Enables the LLM to execute GraphQL queries, sometimes requiring iteration to build the perfect query

Enterprise-Grade Performance

Built with a Rust-powered core, Grafbase's response times, CPU, and memory usage outpace alternatives by 40% or more, making it ideal for high-traffic, performance-critical AI applications.

Advanced Context Management

The Grafbase MCP puts significant effort into returning just the necessary context to your LLM, avoiding bloating its reasoning context with irrelevant parts of your GraphQL schema, leaving more room for useful tokens and helping reduce hallucinations.
