THE RISK

Critical Risk

Why delete_email needs a policy

The tool performs an irreversible action—deletion of email messages—which cannot be undone once executed. Even though 'move to trash' may offer a brief recovery window in some systems, the primary function is destructive data removal. This poses a high blast radius if an AI agent mistakenly deletes important customer support emails, business records, or sensitive correspondence in a Freshdesk support context.

From the tool's definition Tool name 'delete_email' and description 'Delete or move an email to trash' explicitly indicate permanent removal or irreversible relocation of email data.

POLICY

How to control delete_email

PolicyLayer is an MCP gateway — it sits between your AI agents and Freshdesk, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_email:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_email"
  ]
}

delete_email disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Freshdesk — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
