A Go SDK implementing the Model Context Protocol (MCP), letting developers build MCP servers that expose tools, resources, and prompts to LLM applications. It supports multiple transports (stdio, StreamableHTTP, SSE, in-process) with a high-level, type-safe API.
Use cases
- build an MCP server in Go that exposes tools to Claude or other LLM clients
- connect my Go backend's data sources to LLM applications via MCP
- expose internal APIs as MCP tools for AI agents
- run an MCP server over stdio for desktop AI apps
- serve MCP over HTTP with server-sent events
- add OAuth-protected MCP resources
When to choose
- you are writing MCP servers or clients in Go
- you want a high-level, low-boilerplate SDK covering tools, resources, and prompts
- you need multiple transport options including stdio and HTTP
When to avoid
- you need MCP support in another language like Python or TypeScript
- you require advanced MCP capabilities that are still in progress
- your project is not related to LLM-tool integration
