The official Go SDK for Model Context Protocol servers and clients. Maintained in collaboration with Google.
The official Go SDK for the Model Context Protocol, maintained in collaboration with Google, provides everything needed to build MCP servers and clients in Go. The core `mcp` package handles server and client construction, tool registration, and transport management, while separate packages cover raw JSON-RPC transport implementation, OAuth primitives, and OAuth extensions such as ProtectedResourceMetadata. Servers communicate with clients over stdio via `StdioTransport` or subprocess via `CommandTransport`, and tools are registered using typed Go structs with JSON schema annotations derived directly from struct tags. The SDK targets full MCP spec compliance and supports four spec versions dating back to 2024-11-05, with the latest v1.4.0 release adding experimental client-side OAuth against the 2025-11-25 spec. Go developers building MCP-compatible integrations for Claude Desktop, Claude Code, or any MCP-aware host will find this the authoritative starting point, backed by Anthropic and Google rather than a third-party maintainer.
