What is GoMCP?

GoMCP is a framework for building Model Context Protocol (MCP) servers in Go, designed as "Gin for MCP." It lets developers create servers that AI applications like Claude Desktop, Cursor, Kiro, and VS Code Copilot can use to call external tools, read data sources, and use prompt templates.

How to use GoMCP?

Install via go get github.com/zhangpanda/gomcp, then create a server with gomcp.New("name", "version"), register tools using s.ToolFunc(), and start a transport such as s.Stdio(). Use struct tags (e.g., mcp:"required,desc=...") to define parameter schemas with automatic validation.

Core features of GoMCP

  • Struct-tag auto schema generation and validation
  • Typed handlers with automatic parameter parsing and validation
  • Middleware chain: Logger, Recovery, Auth, RateLimit, OTel
  • Tool groups with prefix naming and group-level middleware
  • Adapters for Gin, OpenAPI/Swagger, and gRPC services
  • Built-in Bearer, API Key, Basic auth with RBAC

Use cases of GoMCP

  • Building MCP servers for AI-powered tool calling
  • Importing existing Gin web routes as MCP tools in one line
  • Generating MCP tools from OpenAPI/Swagger documentation
  • Exposing gRPC service methods as MCP tools
  • Developing async task tools with polling and cancellation support
