What device_reauth_status does on Yaver
AI agents call device_reauth_status to retrieve information from Yaver without modifying anything. It is 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.
Why device_reauth_status is rated Low
This tool queries the status of a remote device (healthy, bootstrap, auth-expired, unreachable, offline) to inform decisions, but does not modify state, execute commands, or trigger actions. It is purely an informational read operation with minimal blast radius if misused.
From the tool's definition Tool description explicitly states it 'Inspect[s]' device state and 'Distinguishes' recovery cases without modifying or executing anything. No side effects mentioned.
Attacks that exploit this kind of access
The rule that runs device_reauth_status safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Yaver, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For device_reauth_status, this is the rule to start with:
device_reauth_status is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Yaver, apply this rule, and every device_reauth_status call is checked against it from then on.
Questions about device_reauth_status
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.
