Cancel a loop and its in-flight run.
AI agents call cancel_loop to permanently remove resources in Scrumdo — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Cancelling a loop stops its execution and any in-flight run permanently. This cannot be undone — the run is terminated and the loop is halted. This constitutes an irreversible destructive action against an executing workflow process, making Destructive the most appropriate category.
From the tool's definition 'Cancel a loop and its in-flight run' — cancelling a loop and its active run is an irreversible termination of an ongoing process
Attacks that exploit this kind of access
Cancel a loop and its in-flight run. It is categorised as a Destructive tool in the Scrumdo MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Scrumdo MCP server in PolicyLayer and add a rule for cancel_loop: 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 Scrumdo. Nothing to install.
cancel_loop 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 cancel_loop 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 cancel_loop. 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.
cancel_loop is provided by the Scrumdo MCP server (scrumdollc/scrumdo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
