Deletes a call
AI agents call delete_call to permanently remove resources in Retellai — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of call records is an irreversible operation that cannot be undone. Once a call is deleted, the data is lost. This poses a high severity risk in the context of an AI agent, as it could maliciously or accidentally purge call history, audit trails, or customer communication records. The tool belongs to the Destructive category per the priority rules since it permanently removes data.
From the tool's definition Tool name is 'delete_call' with description 'Deletes a call' — the verb 'delete' combined with the irreversible action of removing a call record matches the Destructive category definition.
Attacks that exploit this kind of access
Deletes a call. It is categorised as a Destructive tool in the Retellai MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Retellai MCP server in PolicyLayer and add a rule for delete_call: 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 Retellai. Nothing to install.
delete_call 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_call 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_call. 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_call is provided by the Retellai MCP server (@abhaybabbar/retellai-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
