Cancel or complete an order. Orders in
AI agents call linktest_cancel to permanently remove resources in Linktest — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Cancelling an order is an irreversible action that terminates an active testing order. While 'complete' might be a softer operation, cancellation typically cannot be undone and may result in loss of testing slots, tester assignments, or in-progress work. The financial implications (via associated billing) and irreversibility push this toward Destructive rather than Write.

Attacks that exploit this kind of access
Cancel or complete an order. Orders in. It is categorised as a Destructive tool in the Linktest MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Linktest MCP server in PolicyLayer and add a rule for linktest_cancel: 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 Linktest. Nothing to install.
linktest_cancel 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 linktest_cancel 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 linktest_cancel. 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.
linktest_cancel is provided by the Linktest MCP server (linktest-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
