AI agents call delete-prompt to permanently remove resources in MCP Prompt Manager — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently deletes prompt files without the ability to recover them (barring external backup systems). Deletion is an irreversible operation that causes data loss. While the blast radius is limited to local prompt files rather than critical infrastructure, the irreversibility and potential loss of user work justifies 'high' severity and the Destructive category, which is more severe than Write.
From the tool's definition Tool name is 'delete-prompt' and description states 'Delete a prompt file'. The action irreversibly removes data from the local filesystem.
Documented attack patterns abuse exactly the kind of access delete-prompt gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Prompt Manager, and nothing reaches the server without passing your rules. This is the rule we recommend for delete-prompt:
{
"version": "1",
"default": "deny",
"hide": [
"delete-prompt"
]
} delete-prompt disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
Free to start. No card required.
Delete a prompt file. It is categorised as a Destructive tool in the MCP Prompt Manager MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MCP Prompt Manager MCP server in PolicyLayer and add a rule for delete-prompt: 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 MCP Prompt Manager. Nothing to install.
delete-prompt 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-prompt 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-prompt. 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-prompt is provided by the MCP Prompt Manager MCP server (tae4an/mcp-prompt-manager). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Prompt Manager, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
