Use to delete a workflow template. Fails with 409 if active runs exist — cancel or wait for them to finish first. Write operation — requires Pro tier or higher.
AI agents call delete_workflow to permanently remove resources in Rentalot MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes workflow templates, which cannot be undone. Although the description mentions it fails if active runs exist (a safeguard), the core function is to permanently remove data. This qualifies as Destructive rather than Write because deletion is not reversible.
From the tool's definition Tool name is 'delete_workflow' and description explicitly states it is used to 'delete a workflow template.' The verb 'delete' combined with the action of removing a template represents irreversible data loss.
Attacks that exploit this kind of access
Use to delete a workflow template. Fails with 409 if active runs exist — cancel or wait for them to finish first. Write operation — requires Pro tier or higher. It is categorised as a Destructive tool in the Rentalot MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Rentalot MCP Server MCP server in PolicyLayer and add a rule for delete_workflow: 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 Rentalot MCP Server. Nothing to install.
delete_workflow 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_workflow 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_workflow. 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_workflow is provided by the Rentalot MCP Server MCP server (rentalot-ai/rentalot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
