AI agents invoke policy-alerts-tool to trigger processes or run actions in Rhombus Node. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
policy-alerts-tool can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

Retrieves Rhombus policy alerts. Policy alerts in the Rhombus system are generated based on user-defined alert policies configured in the Rhombus Console. These policies trigger alerts when specific events occur, such as: * AI & Computer Vision Events: Based on intelligent video analytics for motion, people, vehicles, facial recognition, license plate recognition, or unusual behavior. * Device Status Changes: Like camera disconnections or sensor low battery. * Physical or Visual Tamper: Detection of physical movement of a device or obstruction of a camera's field of view. * Access Control Events: Such as unauthorized access attempts in restricted areas. Alerts are generated on triggers, but are NOT the same as notifications. Only certain alerts generate notifications based on user settings. Can inquire about labels that have been seen. Please note, this is not an exhaustive list, and there may be other types of triggers or events that generate policy alerts within the Rhombus system. This tool allows you to filter existing alerts by existing/expiring, a specific time range (before or after a timestamp in ISO 8601 format), by a list of device UUIDs, or by a list of location UUIDs. You can also specify the maximum number of results to return. The output is provided in JSON format. Pagination: Results are paginated and have a maximum page size. If the response includes a lastEvaluatedKey (for queryType "expiringSoon") or both lastTimestampISO and lastUuid (for queryTypes "existing" and "alert-groups"), more results are available. Pass these values back in the next call using the corresponding input parameters (lastEvaluatedKey, or lastTimestampISO and lastUuid) to retrieve the next page. Repeat until the response no longer includes these fields. IMPORTANT: The "unhealthy-devices" queryType returns historical alert notifications that were triggered for device health issues. It does NOT return live/real-time device connection status. If no device health alert policies are configured, or alerts were dismissed, this may return empty even when devices are offline. To check which devices are currently online/offline, use the get-entity-tool instead. The get-entity-tool returns the current state of all devices including their live connection status (the "connected" field). Request all entity types (CAMERA, DOORBELL_CAMERA, BADGE_READER, etc.) and check the "connected" field on each device to determine which are offline. Output filtering (all tools): - includeFields (string[]): Dot-notation paths to keep in the response (e.g. "vehicleEvents.vehicleLicensePlate"). Omit to return all fields. - filterBy (array): Predicates to filter array items. Each entry: {field, op, value} where op is one of = != > >= < <= contains. All conditions are ANDed. Example: [{field:"vehicleLicensePlate", op:"=", value:"ABC123"}] WARNING: some tool responses exceed 400k characters — use these params to request only the data you need.. It is categorised as a Execute tool in the Rhombus Node MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Rhombus Node MCP server in PolicyLayer and add a rule for policy-alerts-tool: 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 Rhombus Node. Nothing to install.
policy-alerts-tool is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the policy-alerts-tool 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 policy-alerts-tool. 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.
policy-alerts-tool is provided by the Rhombus Node MCP server (rhombus-node-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
