Why delete_note needs a policy

Although the description mentions moving to trash (suggesting possible recovery), the primary function is to remove notes from active use. In most systems, trash is a temporary holding area, but the operation itself is destructive and cannot be undone by normal user actions. An AI agent with access to this tool could maliciously or erroneously delete important notes.

From the tool's definition Tool name 'delete_note' combined with description stating '删除笔记(移入回收站)' (delete note, move to trash). The Chinese description explicitly indicates deletion/removal of notes, which is irreversible from the user's working context.

Documented attack patterns abuse exactly the kind of access delete_note gives an agent:

How to control delete_note

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

policy.json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_note"
  ]
}

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

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