# UptimeDuck

> UptimeDuck is an uptime and server monitoring service. It checks websites, APIs, TCP ports, ping targets, Minecraft servers and DNS blacklists from multiple regions, monitors Linux servers and Kubernetes clusters through a small agent, watches cron jobs through heartbeats, alerts by email, mobile push, SMS, Slack, Discord, Telegram and Matrix, and publishes public status pages. AI assistants can read and manage an account through the UptimeDuck MCP server.

Every account starts on the Free plan, with no credit card. The panel is at https://panel.uptimeduck.com. Support: support@uptimeduck.com.

## AI assistants and MCP

- [MCP server](https://uptimeduck.com/docs/mcp): Connect Claude, Cursor, VS Code or any MCP client. Lists all tools, scopes, rate limits and security notes.
- [For AI agents](https://uptimeduck.com/agents): Short reference for agents acting on a user's behalf: how to connect, what to watch out for, key URLs.

MCP server URL: `https://mcp.uptimeduck.com/mcp` (Streamable HTTP). Clients that support OAuth sign in through the browser, with dynamic client registration and `read` or `write` scopes. Other clients send an API token from the panel (API & Integrations) as `Authorization: Bearer udk_...`. API access is available on every plan, Free included, with a limit on active API tokens per plan (Free 1, Starter 10, Medium 50, Large 100, Enterprise 300). Heartbeat monitors created with `create_heartbeat_monitor` start paused; call `resume_monitor` once the job is pinging its push URL.
