Deletes a webhook by id
AI agents call delete-webhook to permanently remove resources in Mcp Dev — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool performs an irreversible deletion operation. Webhooks are integration configuration elements; deleting one removes event-triggered integrations that may be critical to system operations. While not directly affecting primary data, the destructive nature of deletion and potential operational impact from removing active integrations justifies 'high' severity.
From the tool's definition Tool name explicitly contains 'delete' and description states 'Deletes a webhook by id', indicating irreversible removal of configuration data.
Attacks that exploit this kind of access
Deletes a webhook by id. It is categorised as a Destructive tool in the Mcp Dev MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mcp Dev 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 Mcp Dev. 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 Mcp Dev MCP server (@umbraco-cms/mcp-dev). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
