Delete a cron job
AI agents call delete_cron to permanently remove resources in Ploi MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The delete_cron tool permanently removes a cron job, which is an irreversible destructive action. Once deleted, the scheduled task cannot be recovered without manual recreation. While not as critical as deleting databases or production data, removing cron jobs can disrupt critical automation, backups, or maintenance tasks.
From the tool's definition Tool name 'delete_cron' combined with description 'Delete a cron job' indicates irreversible removal of a scheduled task.
Attacks that exploit this kind of access
Delete a cron job. It is categorised as a Destructive tool in the Ploi MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Ploi MCP Server MCP server in PolicyLayer and add a rule for delete_cron: 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 Ploi MCP Server. Nothing to install.
delete_cron 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_cron 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_cron. 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_cron is provided by the Ploi MCP Server MCP server (sudanese/ploi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
