Hasura MCP Server

This Model Context Protocol (MCP) server provides an advanced interface for AI agents (like those in Cursor or Claude Desktop) to interact with a Hasura GraphQL

What the server does

• Hasura GraphQL Schema (hasura:/schema) —
• Provides the full GraphQL schema definition obtained via standard introspection
• MIME Type: — application/json
• Agents can read this resource to understand the complete structure of the API, including types, fields, arguments, directives, etc
• run_graphql_query —
• Description: — Executes a read-only GraphQL query against the Hasura endpoint. Use this for fetching data when a specific tool isn't available. Ensure the query does not modify data. Example: query { users { id name } }
