Go-MCP is a Go implementation of the Model Context Protocol (MCP) designed to simplify communication between external systems and AI applications. It offers a type-safe, high-performance, and easily deployable SDK for developers building AI-integrated services, leveraging Go's concurrency and static compilation benefits.

How It Works

Go-MCP utilizes a three-layer architecture: Transport, Protocol, and User. The Transport Layer abstracts communication protocols (HTTP SSE/POST, Streamable HTTP, Stdio), allowing for easy extension with new methods like WebSockets or gRPC. The Protocol Layer handles MCP message encoding/decoding and data structures. The User Layer provides idiomatic Go APIs for client and server interactions, ensuring type safety and modularity.

Quick Start & Requirements

• Install: go get github.com/ThinkInAIXYZ/go-mcp
• Requires: Go 1.18 or higher.
• See: Client Example, Server Example, Gin Integration

Highlighted Details

• Full implementation of the MCP specification.
• Supports bidirectional communication via HTTP SSE/POST, Streamable HTTP, and Stdio.
• Integrates with web frameworks like Gin via http.Handler.
• Leverages Go's static compilation for simple deployment.

Limitations & Caveats

The project is actively seeking contributions, and while it implements the MCP specification, the breadth of supported transport protocols beyond HTTP SSE/POST and Stdio might be limited in practice.
