WHAT IT DOES

What delete_webhook does on Lightning Wallet

AI agents call delete_webhook to permanently remove resources in Lightning Wallet, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Deleting a webhook is an irreversible action that removes a configured integration endpoint. While it doesn't move money directly, it could disrupt payment notifications and L402 callbacks, potentially causing financial or operational issues. Classified as Destructive due to the permanent removal of a registered resource.

RECOMMENDED RULE

The rule that runs delete_webhook safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Lightning Wallet, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete_webhook, this is the rule to start with:

delete_webhook Hidden

delete_webhook is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
