THE RISK

Critical Risk

Why pass__trash_item needs a policy

Moving a credential to trash is a destructive action — credentials are removed from active use and placed in trash, which is typically a precursor to permanent deletion. While 'trash' implies some reversibility (vs. permanent delete), credentials are sensitive data and losing access to them can have significant consequences. The action is not a simple write/update but a deletion-class operation.

POLICY

How to control pass__trash_item

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

policy.json

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

pass__trash_item 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 Proton-MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
