Language Server MCP Bridge

MCP server bridging Language Server Protocol (LSP) language servers with AI agents. Enables agents to use LSP capabilities — go-to-definition, find references, hover documentation, auto-completions, diagnostics — from any language server (TypeScript, Python, Go, Rust, etc.) without requiring a full IDE.

Best When

An AI coding agent needs rich code intelligence capabilities — type information, reference navigation, diagnostics — from existing language servers without relying solely on file reading.

Avoid When

Your language doesn't have a quality LSP server, or you need simple pattern-based code search rather than semantic code intelligence.

Use Cases

• Accessing code intelligence (definitions, references, types) from AI coding agents via LSP
• Getting compiler diagnostics and type errors from language servers for debugging agents
• Navigating codebases using go-to-definition and find-references from AI agents
• Providing AI agents with hover documentation and auto-complete suggestions from language servers

Not For

• Teams not using LSP-compatible language servers
• Simple scripting or non-typed languages without good LSP support
• Real-time IDE interaction (this is a bridge for agent use)

Known Gotchas

⚠ Language servers must be installed separately — typescript-language-server, pyright, etc.
⚠ LSP startup time can be significant for large projects — language servers index on first use
⚠ LSP behavior varies by language server implementation — test with your specific language
⚠ Community implementation — integration quality depends on LSP server compliance
