Overview

GraphJin is a powerful API gateway that provides a unified GraphQL and MCP (Model Context Protocol) interface over your databases, files, APIs, and code. Built for AI agents and modern applications, it creates one governed graph connecting multiple data sources through a single endpoint. With real-time subscriptions, caching, authentication, rate limiting, and support for PostgreSQL, MySQL, SQLite, MongoDB, MSSQL, MariaDB, CockroachDB, Oracle, Snowflake, and REST APIs, GraphJin simplifies backend complexity while giving AI systems secure governance over enterprise data. It also functions as an MCP server, letting AI coding agents like Claude Code, Cursor, and Codex query databases through natural language.
