## Why emails_update is rated Medium

This tool modifies existing email records in HubSpot CRM, which is a write operation. The severity is medium because unauthorized updates could compromise email communication history, alter engagement records, or affect business relationships, but the changes are reversible. The tool operates on CRM data rather than infrastructure or financial systems, preventing higher severity classification.

From the tool's own definition: "Tool name is 'emails_update' and description states 'Update an existing email record'. The verb 'update' combined with 'email record' indicates reversible modification of data without deletion or financial impact."

## Use case

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