Check whether Uptime Kuma is reachable on the configured URL. Returns the HTTP status of the entry page and the base URL. No credentials required.
AI agents call uptimekuma_status to retrieve information from Crow without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a simple health check that queries an endpoint and returns status information. It has no capability to modify, delete, or execute operations. The only risk is potential information disclosure about service availability, which is low severity. The tool is clearly read-only in nature.
From the tool's definition Tool performs a check/query of HTTP status with no side effects. Description states 'Check whether Uptime Kuma is reachable' and 'Returns the HTTP status', indicating it retrieves status information only.
Documented attack patterns abuse exactly the kind of access uptimekuma_status gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Crow, and nothing reaches the server without passing your rules. This is the rule we recommend for uptimekuma_status:
{
"version": "1",
"default": "deny",
"tools": {
"uptimekuma_status": {}
}
}uptimekuma_status is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Check whether Uptime Kuma is reachable on the configured URL. Returns the HTTP status of the entry page and the base URL. No credentials required. It is categorised as a Read tool in the Crow MCP Server, which means it retrieves data without modifying state.
Register the Crow MCP server in PolicyLayer and add a rule for uptimekuma_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 Crow. Nothing to install.
uptimekuma_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 uptimekuma_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 uptimekuma_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.
uptimekuma_status is provided by the Crow MCP server (kh0pper/crow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Crow, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
