MCP Go SDK

What is MCP Go SDK?

A Go implementation of the Model Context Protocol (MCP), providing both client and server capabilities for integrating with LLM surfaces. It is built for developers creating MCP-based applications in Go.

How to use MCP Go SDK?

Write an MCP server or client using the SDK’s types, implement required handlers, then wire it to stdio (or future SSE) transport. A typical server binary is compiled and configured in an MCP client like Claude Desktop via a JSON entry specifying the command and arguments.

Key features of MCP Go SDK

• Build MCP clients connecting to any MCP server
• Create MCP servers exposing resources, prompts, and tools
• Use stdio transport; SSE transport coming soon
• Handle all MCP protocol messages and lifecycle events

Use cases of MCP Go SDK

• Expose a file system as MCP resources for LLM context
• Integrate custom data sources with Claude Desktop or other MCP clients
• Implement servers that provide prompts or tools to LLM surfaces
