mcp-language-server

Why we included this project

Claude Desktop and other MCP-capable assistants are better at writing code than at finding the code they should be changing. This small Go server fixes that by running a real language server, gopls or rust-analyzer for instance, and exposing its semantic operations as MCP tools. The model can jump to a symbol's definition, find its references, rename across the project, and pull per-file diagnostics or hover text, so it navigates by meaning instead of grepping text, which usually means fewer missed usages and more accurate edits. You configure it with a short JSON block per project, and since it relies on the same mature language servers your editor already uses, what the agent sees matches what a full IDE would show. If you build tools that depend on an LLM actually understanding a real codebase, this is a practical, low-friction piece to plug in.
