delete_attachment
AI agents call delete_attachment to permanently remove resources in CATS MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion is an irreversible operation that destroys data without the possibility of undo in most systems. In a recruiting workflow context (CATS Applicant Tracking System), attachments likely contain critical candidate documents (resumes, cover letters, portfolios). Unauthorized deletion could permanently lose candidate information and disrupt recruiting pipelines.
From the tool's definition Tool name is 'delete_attachment' which explicitly indicates deletion of attachments. The description is empty, limiting full context, but the verb 'delete' unambiguously signals irreversible removal of data.
Attacks that exploit this kind of access
delete_attachment. It is categorised as a Destructive tool in the CATS MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the CATS MCP Server MCP server in PolicyLayer and add a rule for delete_attachment: 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 CATS MCP Server. Nothing to install.
delete_attachment 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_attachment 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_attachment. 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_attachment is provided by the CATS MCP Server MCP server (vanman2024/cats-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
delete_attachment is one line of CATS MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
