Delete test run
AI agents call delete_run to permanently remove resources in TestRail MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a test run from TestRail, which cannot be undone. Deletion of test data is irreversible and could impact test history, audit trails, and project records. While not financial or involving arbitrary code execution, it is clearly destructive in nature.
From the tool's definition Tool name is 'delete_run' with description 'Delete test run'. The verb 'delete' indicates irreversible removal of data.
Attacks that exploit this kind of access
Delete test run. It is categorised as a Destructive tool in the TestRail MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the TestRail MCP Server MCP server in PolicyLayer and add a rule for delete_run: 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 TestRail MCP Server. Nothing to install.
delete_run 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_run 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_run. 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_run is provided by the TestRail MCP Server MCP server (samuelvinay91/testrail-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
