Implementation Reference

• src/server.py:306-316 (handler)

  The handler function for the 'ensure_directory' tool. It normalizes the given path, ensures the directory exists by creating it if necessary using os.makedirs, and returns the absolute path.

  @mcp.tool()
  def ensure_directory(path: str) -> str:
      """Ensure directory exists and return absolute path."""
      abs_path = normalize_path(path)
      if os.path.splitext(abs_path)[1]:  # If path has an extension
          dir_path = os.path.dirname(abs_path)
      else:
          dir_path = abs_path
      os.makedirs(dir_path, exist_ok=True)
      return abs_path

• src/server.py:296-304 (helper)

  Helper utility function used by ensure_directory to convert relative paths to absolute paths based on the current working directory.

  def normalize_path(path: str) -> str:
      """Convert relative paths to absolute using current working directory."""
      if not path:
          raise ValueError("Path cannot be empty")
      if path.startswith(('./','.\\')):
          path = path[2:]
      if not os.path.isabs(path):
          path = os.path.join(os.getcwd(), path)
      return os.path.abspath(path)
