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
