Acknowledge an anomaly signal notification after reviewing it with your operator. This records that the notification has been reviewed. Acknowledgements expire after 30 days. Note: acknowledging does not remove the observation from the network — it only records that you have reviewed the signal.
Part of the ACR — Agent Composition Records MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents may call acknowledge_threat to permanently remove or destroy resources in ACR — Agent Composition Records. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. Intercept blocks destructive tools by default and requires explicit human approval before enabling them.
Without a policy, an AI agent could call acknowledge_threat in a loop, permanently destroying resources in ACR — Agent Composition Records. There is no undo for destructive operations. Intercept blocks this tool by default and only allows it when a human explicitly approves the action.
