THE RISK

Critical Risk

Why remove_cert needs a policy

The tool deletes a certificate, which is an irreversible action that cannot be undone. Removing a certificate can break authentication, API access, or deployment pipelines depending on what that certificate secures. While the blast radius depends on which certificate is targeted, the destructive nature and potential for significant operational impact justifies 'high' severity.

From the tool's definition Tool name 'remove_cert' explicitly performs a removal/deletion operation on a certificate resource. The verb 'remove' indicates an irreversible destructive action.

POLICY

How to control remove_cert

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

policy.json

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

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