Reviewer Notes

Grafbase offers solid GraphQL API tooling and comprehensive documentation, making it moderately discoverable for agents familiar with GraphQL queries. However, it lacks an MCP server, OpenAPI spec, or llms.txt file, requiring agents to parse GraphQL schemas directly. Account creation requires email verification and dashboard interaction, preventing fully autonomous signup. The GraphQL-native approach is powerful for structured queries but demands agents understand GraphQL syntax; the free tier and sandbox environment support experimentation. Main weakness: no standardized agent discovery mechanisms; main strength: GraphQL's inherent structure provides clear, machine-readable API contracts.
