What is Tool Description?
Quick answer
A tool description is the text an MCP tool declares to explain what it does — the single biggest lever for routing accuracy because LLMs decide whether to call a tool largely from its description.
Full definition
The first ten words of a tool description should contain the action verb and the primary object. Ambiguous descriptions cause false positives (the tool is called when it should not be) or false negatives (the tool is skipped when it should fire). Tightening descriptions is often the cheapest routing fix.
