GraphJin is a Go-based agent app that exposes GraphQL and MCP interfaces over your databases, files, APIs, and code, presenting them as one governed graph for AI agents. It ships with agents.md, a Claude directory, Cursor rules, and a devcontainer, and lists support for many databases including PostgreSQL, MySQL, MongoDB, SQLite, and others via its topics.

Reach for it when you want AI agents to query your data sources through a single governed GraphQL/MCP layer instead of raw database access.

Use it to

  • Expose databases to AI agents via MCP
  • Query data sources with auto-generated GraphQL
  • Set up agent-ready repos with bundled rules and devcontainer
  • Govern agent access across multiple database engines

For Developers building AI agents that need governed data access
