Overview

A Go middleware that adds Model Context Protocol (MCP) endpoints to any Gin-based API with a single line of code. It automatically exposes existing routes as MCP tools, allowing AI agents to interact with the API through a standardized interface.

Best for

Use cases

• Quickly add MCP support to an existing Gin API without rewriting routes
• Expose backend services as tools for AI agents or assistants
• Prototype MCP integrations in Go projects using the Gin framework

Pros

• Minimal integration effort: one line of code to enable MCP
• Leverages existing Gin route definitions automatically
• Lightweight and focused on a single framework

Cons

• Limited to Gin framework, not usable with other Go routers
• Small community and low star count may indicate limited testing
• No built-in authentication or rate limiting for MCP endpoints
