## What it is
An MCP server written in Go that runs a language server and exposes LSP semantic tools (go to definition, references, rename, diagnostics) to MCP-enabled LLM clients. It helps AI assistants navigate and understand codebases more accurately.

## Use cases
- let an LLM find symbol definitions in a codebase
- give AI coding assistants access to diagnostics
- enable LLM-driven symbol renaming via language servers
- find all references to a function with an AI agent
- connect gopls or rust-analyzer to Claude Desktop

## When to choose
- you use MCP clients like Claude Desktop and want precise code navigation tools
- you want LLMs to leverage language server intelligence instead of grep-based search

## When to avoid
- your MCP client has no tool support for external servers
- you don't want to install and configure language servers per language

## Facets
- artifact type: service
- maturity: active
- function: mcp, developer-tools, documentation
- domain: developer-tools, large-language-models
- platform: go, cli, cross-platform
- tags: language-server-protocol, mcp-server, code-navigation, llm-tools, code-intelligence, ai-agents
