• src/tools/pub_sub.py:45-61 (handler)

  The main handler function for the 'unsubscribe' tool. It uses Redis pubsub to unsubscribe from the specified channel and returns a success or error message. Registered via @mcp.tool() decorator.

  @mcp.tool()
  async def unsubscribe(channel: str) -> str:
      """Unsubscribe from a Redis channel.
  
      Args:
          channel: The Redis channel to unsubscribe from.
  
      Returns:
          A success message or an error message.
      """
      try:
          r = RedisConnectionManager.get_connection()
          pubsub = r.pubsub()
          pubsub.unsubscribe(channel)
          return f"Unsubscribed from channel '{channel}'."
      except RedisError as e:
          return f"Error unsubscribing from channel '{channel}': {str(e)}"
