MCP LSP Go

A Model Context Protocol (MCP) server that allows AI assistants like Claude to interact with Go's Language Server Protocol (LSP) and benefit from advanced Go code analysis features.

Overview

This MCP server helps AI assistants to:

Use LSP to analyze Go code
Navigate to definitions and find references
Check code diagnostics
Get hover information for symbols
Get completion suggestions

Architecture

This project uses the mark3labs/mcp-go library to implement the Model Context Protocol. The MCP integration enables seamless communication between AI assistants and Go tools.

The server communicates with gopls, the official language server for Go, via the Language Server Protocol (LSP).

Features

LSP Integration: Connection to Go's Language Server Protocol for code analysis
Code Navigation: Finding definitions and references in the code
Code Quality: Getting diagnostics and errors
Advanced Information: Hover information and completion suggestions

MCP Tools

The MCP server provides the following tools:

Tool	Description
`go_to_definition`	Navigate to the definition of a symbol
`find_references`	Find all references to a symbol
`check_diagnostics`	Get diagnostics for a file
`get_hover_info`	Get detailed information about a symbol
`get_completion`	Get completion suggestions at a position
`analyze_coverage`	Analyze test coverage for Go code

Usage Example

Using the server with AI assistants that support MCP:

# Ask the AI to get information about the code
Can you find the definition of the `ServeStdio` function in this project?

# Ask for diagnostics
Are there any errors in my main.go file?

# Ask for information about a symbol
What does the Context.WithTimeout function do in Go?
