CCLSP

MCP server that bridges LLM-based coding agents with Language Server Protocol servers, enabling AI assistants to jump to definitions, find references, rename symbols, and get diagnostics across codebases. Intelligently handles imprecise line/column positioning from AI by testing multiple position combinations.

Best When

You want Claude Code or another MCP-compatible AI agent to have precise code navigation and refactoring capabilities across multiple languages, leveraging existing LSP infrastructure.

Avoid When

Your IDE already provides sufficient LSP integration and you don't need AI-driven code navigation, or you work exclusively in languages without LSP support.

Use Cases

• Navigate to symbol definitions without manual searching in AI coding workflows
• Find all references to a symbol across a workspace from an AI agent
• Perform safe workspace-wide symbol renames through natural language
• Get language server diagnostics (errors, warnings) for AI-assisted debugging
• Add LSP intelligence to Claude Code for any language with an LSP server

Not For

• Standalone IDE replacement - requires an MCP-compatible AI client
• Languages without an LSP server implementation
• Non-code tasks or general-purpose AI assistance
