How can I integrate with a Gin server?

[lariel-fernandes]

I have a Gin server with other endpoints already, and I want to expose the SSE server over a prefix like /mcp/sse.

I've seen some examples of using a custom http server, but it is not clear how to set it up with Gin, which is a rather popular framework.

For reference, see this example of Gin integration in another MCP SDK: https://github.com/ThinkInAIXYZ/go-mcp?tab=readme-ov-file#integration-with-gin-server

Answering my own question here, I hope it might be useful for others:

mcpServer := server.NewMCPServer("my_mcp", "0.0.0")

// add tools

sseServer := server.NewSSEServer(
	mcpServer,
	server.WithSSEEndpoint("/mcp/sse"),
	server.WithMessageEndpoint("/mcp/message"),
)

// engine *gin.Engine

engine.GET("/mcp/sse", func(c *gin.Context) {
	sseServer.SSEHandler().ServeHTTP(c.Writer, c.Request)
})

engine.POST("/mcp/message", func(c *gin.Context) {
	sseServer.MessageHandler().ServeHTTP(c.Writer, c.Request)
})
