Why deleteWebhookWithId is rated Critical
This tool permanently removes a webhook configuration by ID, which is an irreversible action that cannot be undone. Webhook deletion could disrupt critical integrations and event notifications in FusionAuth. While not as severe as deleting user accounts or financial data, the permanent nature of the deletion and potential operational impact justifies Destructive classification with high severity.
From the tool's definition Deletes the webhook for the given Id. The verb 'Deletes' clearly indicates an irreversible removal operation.

The rule that runs deleteWebhookWithId safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Fusionauth, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For deleteWebhookWithId, this is the rule to start with:
deleteWebhookWithId is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Fusionauth, apply this rule, and every deleteWebhookWithId call is checked against it from then on.
