Tool `count` accepts unconstrained string input
The following string parameter(s) have no `maxLength` constraint: `collection`, `database`. Unbounded strings let an attacker stuff arbitrary payloads through the tool, including indirect-injection content.
fix: Add a `maxLength` to each string property, or constrain with an `enum` or `pattern`. Most legitimate tool inputs fit under a few hundred bytes.
