THE RISK

Why delete_gist_file needs a policy

This tool irreversibly deletes a file from a gist, destroying data that cannot be recovered through normal operation. Deletion is a destructive action per the classification rules. While the blast radius is somewhat limited (a single file within a gist), the irreversible nature and potential loss of important personal knowledge, notes, or prompts warrants a 'high' severity rating.

From the tool's definition Tool name is 'delete_gist_file' and description states 'Delete a file from a gist'. The verb 'delete' indicates irreversible removal of data.

POLICY

How to control delete_gist_file

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_gist_file"
  ]
}

delete_gist_file disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register GistPad MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
