One governed graph for AI agents — GraphQL + MCP over your databases, files, APIs, and code
GraphJin is a compiler and runtime that gives AI agents a governed graph-based way to work with databases, files, source code, workflows, and other systems through GraphQL and MCP. It is also used as a GraphQL-to-database service, API gateway, Go library, and real-time subscription server. The catalogue add-ons connect agents to GraphJin or support its agent workflow.
