GoMCP - Go Model Context Protocol Library
GoMCP is a comprehensive Go library designed to provide idiomatic tools for building applications that communicate using the Model Context Protocol (MCP).
Why GoMCP?
The Model Context Protocol enables powerful interactions between language models (or other agents) and external tools or data sources. GoMCP was built to make implementing both MCP clients (consumers of tools/resources) and MCP servers (providers of tools/resources) straightforward and efficient in Go. It handles the underlying JSON-RPC 2.0 messaging and provides clear interfaces for defining capabilities and managing communication transports.
Specification
GoMCP aims to be fully compliant with the official Model Context Protocol specification (Protocol Revision: 2025-03-26). It supports core features like initialization, tool definition and execution, resource discovery and access, prompts, progress reporting, and cancellation.
