Overview
GraphJin is a compiler and runtime environment that offers unified access to existing systems—such as databases, files, APIs, and code—for AI agents via GraphQL + MCP. AI agents can discover and validate queries, execute approved tasks, and have each answer checked on the server. GraphJin supports multiple databases and storage systems, including PostgreSQL, MySQL, MongoDB, and more. It is not only suitable for AI agents but also functions as a high-performance GraphQL-to-database compiler, a Go library, and an independent API service. Ideal for developers and teams needing unified access across multiple systems.
