delete_webhook
AI agents call delete_webhook to permanently remove resources in Thesma MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of webhooks cannot be undone and represents an irreversible loss of data or configuration. In the context of a data-access server managing SEC filings, employment, demographics, and lending data, deleting a webhook could disrupt monitoring, data pipelines, or integrations that depend on that webhook. This fits the Destructive category.
From the tool's definition Tool name 'delete_webhook' explicitly indicates a deletion operation. The description is empty, providing no mitigating context about scope or reversibility.
Attacks that exploit this kind of access
delete_webhook. It is categorised as a Destructive tool in the Thesma MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Thesma 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 Thesma 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 Thesma MCP Server MCP server (thesma-dev/thesma-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
delete_webhook is one line of Thesma MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
