What link_person_to_deal does on Mcp Pipedrive

WHY IT NEEDS A POLICY

Why link_person_to_deal needs a policy

This tool modifies deal data by linking a person to a deal, which is a reversible write operation. The phrase 'replaces any previously-linked contact' confirms it modifies existing state. While it changes data, it is not destructive (the change can be undone by linking a different person), not financial (no money moves), and not code execution.

From the tool's definition Set person_id on a deal (replaces any previously-linked contact). Auto-backed up.
