• src/tools/json.py:70-91 (handler)

  The json_del tool handler function, decorated with @mcp.tool() which also handles registration. It deletes a JSON value at the specified path in a Redis-stored JSON document and returns a success or error message.

  @mcp.tool()
  async def json_del(name: str, path: str = "$") -> str:
      """Delete a JSON value from Redis at a given path.
  
      Args:
          name: The Redis key where the JSON document is stored.
          path: The JSON path to delete (default: root '$').
  
      Returns:
          A success message or an error message.
      """
      try:
          r = RedisConnectionManager.get_connection()
          deleted = r.json().delete(name, path)
          return (
              f"Deleted JSON value at path '{path}' in '{name}'."
