About isaacphi/mcp-language-server
mcp-language-server provides an MCP wrapper around existing language servers. It exposes semantic code actions like go to definition, find references, rename, and diagnostics to any MCP-compatible client.
Best for
Developers building MCP-based IDEs or automating code analysis via AI agents
Use cases
- Query code symbols and references from an AI coding agent
- Automate refactoring tasks like rename across a project
- Integrate language-server diagnostics into a chat-based development flow
Notes
1,539 stars on GitHub. Last updated 2026-03-01. Licensed BSD-3-Clause.
Pros
- Leverages stable LSP infrastructure already maintained per language
- Simple Go implementation with 1500+ stars indicates community trust
- Works with any MCP client without per-language integration work
Cons
- Depends on external language servers being correctly installed per project
- Limited to actions the underlying LSP server exposes (no custom analysis)
- No built-in multi-language orchestration; each language needs its own server

No install recipe yet. We write one for Claude Code, Claude Desktop, Cursor, VS Code, Codex and ChatGPT when the server is in the official MCP registry with a package or remote address we can use.
Until then, follow the project's own README, or the setup the listing publishes under How to set it up.
