An MCP toolkit that gives coding agents language-server-backed, symbol-level code understanding (find symbols, references, edit by symbol) so they operate faster and more reliably than line-number or grep-based tools.

Strengths

  • Language-server-precise symbol and reference operations
  • Agent-first, high-level abstractions over raw line-number tools

Tradeoffs

  • Needs a language server per project
  • Heavier to set up than plain search
