AI agents call webhooks_delete to permanently remove resources in Ghost MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Webhook deletion cannot be undone and removes configured integrations or automations. This is a destructive operation with potential business impact if used inappropriately. Confidence is slightly reduced due to the empty description, but the tool name and deletion semantics justify the Destructive category with high severity. If webhooks trigger critical external services, deletion could disrupt operations.
From the tool's definition Tool name 'webhooks_delete' indicates irreversible deletion of webhook configuration data. The method name 'delete' is a destructive operation.

PolicyLayer is an MCP gateway — it sits between your AI agents and Ghost MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for webhooks_delete:
{
"version": "1",
"default": "deny",
"hide": [
"webhooks_delete"
]
}webhooks_delete disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
