Delete an activity record (permanent).
AI agents call delete_activity 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.
This tool permanently deletes activity records without the possibility of reversal. In an ATS (Applicant Tracking System) context, activity records typically document recruiter actions, candidate interactions, communications, and workflow history. Permanent deletion of these records destroys audit trails and historical context that may be critical for compliance, legal discovery, or recruitment process integrity.
From the tool's definition Tool name is 'delete_activity' with description 'Delete an activity record (permanent).' The word 'Delete' combined with 'permanent' explicitly indicates irreversible data destruction.
Attacks that exploit this kind of access
Delete an activity record (permanent). 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_activity: 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_activity 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_activity 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_activity. 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_activity 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_activity 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.
