• src/mcp_ty/server.py:146-169 (handler)

  The implementation of the 'start_project' MCP tool, which initializes the TyLspClient and starts the analysis for a given project path.

      if not path.is_dir():
          return _error(f"Not a directory: {project_path}")

          try:
              await _lsp_client.stop()
