cclsp - not your average LSP adapter

cclsp is a Model Context Protocol (MCP) server that seamlessly integrates LLM-based coding agents with Language Server Protocol (LSP) servers. LLM-based coding agents often struggle with providing accurate line/column numbers, which makes naive attempts to integrate with LSP servers fragile and frustrating. cclsp solves this by intelligently trying multiple position combinations and providing robust symbol resolution that just works, no matter how your AI assistant counts lines.

Why cclsp?

When using AI-powered coding assistants like Claude, you often need to navigate codebases to understand symbol relationships. cclsp bridges the gap between Language Server Protocol capabilities and Model Context Protocol, enabling:

• 🔍 Instant symbol navigation - Jump to definitions without manually searching
• 📚 Complete reference finding - Find all usages of functions, variables, and types
• ✏️ Safe symbol renaming - Rename across entire codebases with confidence
• 🌍 **Universal lang...
