MCP-Go

What is MCP-Go?

MCP-Go is a Go implementation of the Model Context Protocol (MCP), a lightweight protocol for efficient communication between AI models and applications. It provides a robust framework with client-server architecture, concurrent design, and type-safe APIs, suitable for developers building AI-integrated systems in Go.

How to use MCP-Go?

Install via go get github.com/OkutaniDaichi0106/mcp-go. Use the mcp.NewServer() or mcp.NewClient() factory, register tools/resources/prompts with handler functions, then create a transport (Stdio, HTTP, or custom) and call Accept() (server) or Dial() (client) to obtain a session.

Key features of MCP-Go

• Client-Server Architecture with full implementation of both roles
• Transport Flexibility via Stdio, WebSockets, or HTTP
• Concurrent Design using Go’s goroutines and channels
• Type-Safe APIs to prevent runtime errors
• Modular Components with a handler-based design pattern
• Session Management with proper lifecycle handling

Use cases of MCP-Go

• Building MCP servers that expose tools, resources, and prompts to AI models
• Creating MCP clients to consume capabilities from MCP servers
• Enabling standardized message exchange between AI models and applications
