Delete a webhook
AI agents call delete_webhook to permanently remove resources in Basecamp MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a webhook removes a configured integration endpoint permanently and cannot be easily undone. This prevents Basecamp from sending notifications to that endpoint going forward, disrupting automated workflows or monitoring systems that depend on it. While not directly exposing secrets or data, it is a destructive operation that irreversibly removes infrastructure configuration.
From the tool's definition Tool name is 'delete_webhook' with description 'Delete a webhook'. The verb 'delete' is explicit and indicates irreversible removal of a webhook configuration.
Attacks that exploit this kind of access
Delete a webhook. It is categorised as a Destructive tool in the Basecamp MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Basecamp MCP Server 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 Basecamp MCP Server. 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 Basecamp MCP Server MCP server (jhliberty/basecamp-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
