The context of the comment would help; the meaning would vary quite a bit. When describing a person this word would usually mean that the person is being used by someone or by some system; it would have a negative connotation in most cases. Imagine hearing a preacher talk about a drug dealer, for example. He might say "That man is a tool of the devil!"
Since it is slang the actual meaning may be different but the term "tool" has become a slang word for a male appendage. The speaker though may have just changed the word fool to rhyme with tool. I would interpret it to mean don't be foolish and obnoxious.
Don't let someone use you as their "tool"...for their good and not your own...don't be someones slave.
It means someone is being used like, a tool
Example:
You're such a toll just letting him push you around like that.
One who lacks the mental capacity to know he is being used.
Basically you are a tool if people use you for a laugh. Most of the time they just keep you around to laugh at you.
A person being used as tool would depend on the use and circumstances.
It could be a gambit or a surrogate.
A puppet or a fool.
