What is MCP4Go?

MCP4Go is a Go implementation of the Model Context Protocol (MCP), designed to simplify the development of AI applications by abstracting away protocol complexities. It targets developers building MCP servers in Go.

How to use MCP4Go?

Import the package in your Go application using go get github.com/mcp4go/mcp4go. The README demonstrates creating a server with a stdio transport, configuring server info, instructions, and tools (e.g., a time tool). Run the server with srv.Run(ctx) after setting up a context and signal handling.
