Implementation Reference
- src/text_editor/server.py:501-562 (handler)The main handler function for the 'select' MCP tool. It validates the line range, reads the current file, computes a unique ID for the selected content using calculate_id, stores the selection in instance variables, and returns details including the lines, ID, and status for use in subsequent overwrite operations.async def select( start: int, end: int, ) -> Dict[str, Any]: """ Select lines from for subsequent overwrite operation.
