Overview

Gin-MCP is an opinionated, zero-configuration library that automatically exposes your existing Gin endpoints as Model Context Protocol (MCP) tools. It enables effortless integration with MCP clients like Cursor, Claude Desktop, and other MCP-enabled tools. The library automatically discovers routes, infers schemas, and provides features like direct Gin integration, parameter preservation, and customizable schemas. Gin-MCP is designed for developer productivity, allowing you to connect your Gin API to MCP clients with minimal setup and maximum flexibility, while working with your existing API without needing to change any code.

Q&A

Does Gin-MCP support authentication headers and proxy environments?

It forwards the client’s Authorization header to internal tool calls, enabling JWT‑protected APIs. It also resolves dynamic BaseURL, making it suitable for proxy or multi‑tenant deployments.

Asked by Malik Rasheed · Dec 11, 2025

Can I customize the schemas or control which endpoints are exposed?

Yes. Use `RegisterSchema` to manually define schemas for specific routes and filter exposure with operation IDs or tags. This gives fine‑grained control while still benefiting from the automatic discovery feature.

Asked by Zara Ahmed · Oct 21, 2025

Is any configuration required to start using MCP with Gin-MCP?

No, the library is zero‑configuration by default. It automatically discovers registered routes, infers schemas from parameters and request/response types, and mounts the MCP server. Optional customization is available via RegisterSchema or selective exposure if needed.

Asked by Nadia Petrova · Oct 2, 2025

How do I enable MCP features in my existing Gin API?

Add Gin-MCP to your project with `go get github.com/ckanthony/gin-mcp` and mount it onto your gin.Engine. A single line of code activates automatic route discovery and schema inference, exposing all endpoints as MCP tools without modifying your existing API.
