AI agents may call transcribe_cancel to permanently remove or destroy resources in Scriptivox. 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 transcribe_cancel in a loop, permanently destroying resources in Scriptivox. 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.

Cancel an in-flight Scriptivox transcription and release any reserved balance. Idempotent. Returns 409 CONFLICT on already-terminal jobs. Requires a configured API key.. It is categorised as a Destructive tool in the Scriptivox MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Scriptivox MCP server in PolicyLayer and add a rule for transcribe_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 Scriptivox. Nothing to install.
transcribe_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 transcribe_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 transcribe_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.
transcribe_cancel is provided by the Scriptivox MCP server (oci:docker.io/sparkleofficialmain/scriptivox-mcp-server:1.1.3). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
