ai AGENTS.md

A repository guide for UptimeRobot, a service that checks websites, APIs, servers, DNS, and other services and reports when they go down.

In plain words
What is it for?
Use it to create, inspect, and control monitors, configure alert destinations, review downtime incidents, label monitors, and schedule periods when alerts are suppressed.
Why use it?
It explains the service’s monitors, incidents, alerts, tags, and maintenance windows so an agent can manage monitoring correctly.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ai AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AGENTS.md — UptimeRobot

Orientation for coding agents (Claude Code, Cursor, Codex, Aider, etc.) that need to create, inspect, or control UptimeRobot monitors on a user's behalf.

What UptimeRobot is

UptimeRobot monitors websites, APIs, servers, DNS, and services. It probes each target on an interval (minimum 30s on paid plans), records up/down state plus response times, opens incidents on downtime, and fires alerts (email, SMS, webhooks, Slack, etc.) through alert contacts.

Key entities:

  • Monitor — one probe against one target. Has a type (HTTP, KEYWORD, PING, PORT, HEARTBEAT, DNS, API, UDP), a URL/host, an interval, and a status (UP, DOWN, PAUSED, NOT_STARTED, etc.).
  • Incident — a downtime event. Opens when a monitor goes down, closes when it recovers. Has logs, checker IPs, traceroute.
  • Alert contact — a destination (email, Slack, webhook, SMS, Telegram, etc.) attached to monitors with a threshold and recurrence.
  • Tag — free-form label assigned to monitors.
  • Maintenance window — scheduled period where alerts for attached monitors are suppressed.

Plans: Free, Solo, Team, Enterprise. Availability of specific monitor types and minimum intervals depends on the active plan. The MCP server enforces all limits.

How to talk to UptimeRobot

Use the remote MCP server:

  • URL: https://mcp.uptimerobot.com/mcp
  • Transport: HTTP (streamable), launched via mcp-remote (npx -y mcp-remote@latest https://mcp.uptimerobot.com/mcp).
  • Auth: OAuth. On first connection mcp-remote opens a browser to log into UptimeRobot and authorize — no API key to paste. (For headless/CI where a browser can't run, connect over plain HTTP with an Authorization: Bearer <API_KEY> header instead.)

All 32 tools operate on the authorized account. There is no account impersonation.

First-time setup (Claude Code, Cursor, or any MCP client): see skills/setup/SKILL.md.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
