• src/tools/set.py:35-55 (handler)

  The main handler function for the 'srem' tool, decorated with @mcp.tool() for registration. It removes a value from a Redis set using r.srem and returns appropriate success or error messages.

  @mcp.tool()
  async def srem(name: str, value: str) -> str:
      """Remove a value from a Redis set.
  
      Args:
          name: The Redis set key.
          value: The value to remove from the set.
  
      Returns:
          A success message or an error message.
      """
      try:
          r = RedisConnectionManager.get_connection()
          removed = r.srem(name, value)
          return (
              f"Value '{value}' removed from set '{name}'."
              if removed
              else f"Value '{value}' not found in set '{name}'."
          )
      except RedisError as e:
