Grafbase
By thumbsupordown
Grafbase builds its MCP server into the Grafbase Gateway and CLI rather than shipping it separately, so a GraphQL API gains an agent interface with no extra service to deploy, authenticate or access-control. Its design targets the real failure mode of large schemas: instead of dumping the whole SDL into the context window, a search tool returns only the relevant subset, introspect fetches specific types on demand, and execute runs the resulting query. Listens on 127.0.0.1:5000/mcp by default.
Tools
execute
Execute a GraphQL query or mutation against the graph behind the gateway.
introspect
Request detailed information about specific types in the GraphQL schema.
search
Return the most relevant subset of the GraphQL schema as SDL for a natural-language query.
