Why delete_prompt needs a policy

This tool performs an irreversible deletion operation on stored prompts. Even though the blast radius is limited to prompt data (not production systems or financial assets), deletion cannot be undone without external recovery mechanisms. This fits the Destructive category per the classification rules, as it removes data that cannot be restored by the tool's own operations.

From the tool's definition Tool name is 'delete_prompt' with description 'Delete a prompt by name'. The verb 'delete' indicates irreversible removal of data.

POLICY

How to control delete_prompt

PolicyLayer is an MCP gateway — it sits between your AI agents and Smart Prompts MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_prompt:

policy.json

{
  "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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
