AI agents may call devbox_runs_cancel_all to permanently remove or destroy resources in Devbox. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. PolicyLayer blocks destructive tools by default and requires explicit human approval before enabling them.
Without a policy, an AI agent could call devbox_runs_cancel_all in a loop, permanently destroying resources in Devbox. There is no undo for destructive operations. PolicyLayer blocks this tool by default and only allows it when a human explicitly approves the action.
Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

These attack patterns abuse exactly the kind of access devbox_runs_cancel_all gives an agent. Each links to the full case and the policy that stops it:
Other destructive tools across the catalogue. The same approach applies to each: deny by default, or require human approval.
Cancel all non-terminal runs for a project. Use when cleaning up stuck or unwanted runs.. It is categorised as a Destructive tool in the Devbox MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Devbox MCP server in PolicyLayer and add a rule for devbox_runs_cancel_all: 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 Devbox. Nothing to install.
devbox_runs_cancel_all 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 devbox_runs_cancel_all 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 devbox_runs_cancel_all. 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.
devbox_runs_cancel_all is provided by the Devbox MCP server (devbox-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
