Move an email to the Trash folder by its IMAP message ID.
AI agents call delete_email to permanently remove resources in AOL Mail MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Although the description says 'Move...to Trash' (which is technically reversible), email deletion is conventionally treated as destructive in security contexts because: (1) users typically expect deleted emails to be gone, (2) Trash folders are often auto-purged, (3) an AI agent could delete many important emails before a human notices, and (4) the sibling tool 'delete_all_in_folder' shows mass-deletion capability.
From the tool's definition Tool name 'delete_email' and description 'Move an email to the Trash folder' indicates removal of email data. The sibling tool 'delete_all_in_folder' further confirms this server's destructive capabilities.
Attacks that exploit this kind of access
Move an email to the Trash folder by its IMAP message ID. It is categorised as a Destructive tool in the AOL Mail MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the AOL Mail MCP Server MCP server in PolicyLayer and add a rule for delete_email: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches AOL Mail MCP Server. Nothing to install.
delete_email is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_email rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for delete_email. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
delete_email is provided by the AOL Mail MCP Server MCP server (kubegrind/aol-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
