• char_index_mcp/server.py:259-271 (handler)

  The handler function for the 'count_chars' tool. It takes a text string and returns a dictionary with character statistics: total length, length without spaces, counts of letters, digits, spaces, and special characters.

  @mcp.tool()
  def count_chars(
      text: Annotated[str, "Text to analyze"]
  ) -> dict:
      """Count character statistics. Returns dict with total, without_spaces, letters, digits, spaces, special."""
      return {
          "total": len(text),
          "without_spaces": len(text.replace(" ", "")),
          "letters": sum(1 for c in text if c.isalpha()),
          "digits": sum(1 for c in text if c.isdigit()),
          "spaces": sum(1 for c in text if c.isspace()),
          "special": sum(1 for c in text if not c.isalnum() and not c.isspace())
      }
