Inspect an owned remote Yaver machine's recovery state. Distinguishes healthy, bootstrap, auth-expired, unreachable, and offline cases so coding agents can decide whether to wait, reconnect, or start re-auth.
AI agents call device_reauth_status to retrieve information from Yaver without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
device_id | string | Yes | Owned Yaver device ID, unique prefix, or exact device name. |
Parameters from the server's own tool schema.
Even though device_reauth_status only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
Inspect an owned remote Yaver machine's recovery state. Distinguishes healthy, bootstrap, auth-expired, unreachable, and offline cases so coding agents can decide whether to wait, reconnect, or start re-auth. It is categorised as a Read tool in the Yaver MCP Server, which means it retrieves data without modifying state.
device_reauth_status accepts 1 parameter: device_id. Required: device_id. The full parameter table on this page comes from the server's own tool schema.
Register the Yaver MCP server in PolicyLayer and add a rule for device_reauth_status: 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 Yaver. Nothing to install.
device_reauth_status is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the device_reauth_status 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 device_reauth_status. 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.
device_reauth_status is provided by the Yaver MCP server (yaver-cli). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
