Cancel an active deploy session; terminal action and no further calls needed. 取消进行中的部署会话；这是终止动作，之后无需继续调用。
AI agents call cancel_deploy_session to permanently remove resources in Remote Demo MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
While cancellation itself doesn't delete files, it terminates an active deployment process in a way that cannot be undone—the session is gone and subsequent state recovery would require manual intervention or redeployment. This matches the Destructive category (actions that cannot be undone).
From the tool's definition 'Cancel an active deploy session; terminal action' indicates an irreversible termination of an in-flight deployment operation. Once cancelled, the session state cannot be recovered.

Register the Remote Demo MCP server in PolicyLayer and add a rule for cancel_deploy_session: 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 Remote Demo MCP. Nothing to install.
cancel_deploy_session 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_deploy_session 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_deploy_session. 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_deploy_session is provided by the Remote Demo MCP server (jake-bcn/remote-demo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
