WHAT IT DOES

What update_deal does on Mcp Pipedrive

AI agents use update_deal to create or update resources in Mcp Pipedrive — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Pipedrive environment.

WHY IT NEEDS A POLICY

Why update_deal needs a policy

This tool modifies deal records in Pipedrive, a CRM system critical to sales operations. While the changes are reversible via snapshots, an AI agent could misuse this to corrupt deal data, alter pipeline status, change financial terms, or interfere with active sales processes. The high severity reflects the business-critical nature of deal data and the potential impact on revenue operations and deal tracking.

From the tool's definition Tool description states 'Update one or more fields on a deal', and the server manages 'Pipedrive deals' which are core business pipeline data. The presence of auto-snapshots indicates reversibility, classifying this as Write rather than Destructive.
