AI agents call uptime_monitor_add 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 |
|---|---|---|---|
url | string | Yes | |
name | string | Yes | |
interval_sec | integer | — | Check interval in seconds (default 60) |
expected_status | integer | — | Expected HTTP status (default 200) |
Parameters from the server's own tool schema.
Even though uptime_monitor_add 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
Add a URL to uptime monitoring. Replaces BetterStack ($10-25/mo). Alerts via Telegram/Discord/Slack. It is categorised as a Read tool in the Yaver MCP Server, which means it retrieves data without modifying state.
uptime_monitor_add accepts 4 parameters: url, name, interval_sec, expected_status. Required: url, name. 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 uptime_monitor_add: 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.
uptime_monitor_add 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 uptime_monitor_add 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 uptime_monitor_add. 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.
uptime_monitor_add 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.
