## Why update_person is rated Medium

This tool modifies existing person records in the CRM system. Updates are reversible (the previous state can be restored), so it falls under Write rather than Destructive. Severity is medium because unauthorized updates to CRM person records could corrupt customer data and business processes, but the impact is limited to a single person record and can be undone.

From the tool's own definition: "Tool name 'update_person' and description 'Update an existing person' indicate modification of existing data."

## Use case

AI agents use update_person to create or update resources in Twenty CRM MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Twenty CRM MCP Server environment.
