Permanently delete an evaluator. This action cannot be undone.
AI agents call delete_evaluator to permanently remove resources in Respan 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 data (an evaluator resource) with no recovery mechanism. Destructive is the correct category as it is more severe than Write (which is reversible). The high severity reflects that accidental deletion could cause significant loss of evaluation configuration or history in a monitoring/management system.
From the tool's definition Tool description states 'Permanently delete an evaluator. This action cannot be undone.' The use of 'Permanently delete' and 'cannot be undone' explicitly indicates irreversible data destruction.
Attacks that exploit this kind of access
Permanently delete an evaluator. This action cannot be undone. It is categorised as a Destructive tool in the Respan MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Respan MCP Server MCP server in PolicyLayer and add a rule for delete_evaluator: 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 Respan MCP Server. Nothing to install.
delete_evaluator 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_evaluator 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_evaluator. 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_evaluator is provided by the Respan MCP Server MCP server (respanai/respan-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
