Remove a previously registered webhook by its ID.
AI agents call delete_webhook to permanently remove resources in Manus MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a webhook, which cannot be undone without recreating it. Deletion of infrastructure configurations like webhooks qualifies as destructive—an agent deleting webhooks for critical notifications could disrupt real-time integrations and alerting systems. While not as severe as deleting primary data, webhook removal is a non-reversible action affecting system integration and observability.
From the tool's definition Tool name 'delete_webhook' combined with description 'Remove a previously registered webhook by its ID' indicates irreversible deletion of a webhook configuration.
Attacks that exploit this kind of access
Remove a previously registered webhook by its ID. It is categorised as a Destructive tool in the Manus MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Manus MCP server in PolicyLayer and add a rule for delete_webhook: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Manus MCP. Nothing to install.
delete_webhook is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_webhook rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for delete_webhook. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
delete_webhook is provided by the Manus MCP server (nanameru/manus-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
