Why delete_email is rated Critical
This tool removes email data permanently without the ability to undo the action. Misuse by an AI agent could result in loss of important communications, evidence, or records. The word 'Permanently' confirms this is irreversible, placing it in the Destructive category rather than Write.
From the tool's definition Tool name 'delete_email' combined with description 'Permanently delete an email message' explicitly indicates irreversible deletion of data.
Attacks that exploit this kind of access
The rule that runs delete_email safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Microsoft MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete_email, this is the rule to start with:
delete_email is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Microsoft MCP, apply this rule, and every delete_email call is checked against it from then on.
