Examples

Check status of all your monitors

> Show me all my monitoring checks and their current status

Investigate downtime

> Show me the downtime history for check abc123

Get performance metrics

> Get metrics for check abc123 between 2024-01-01 and 2024-01-31, grouped by time

Create a new monitor

> Create a check for https://myapp.com every 30 seconds with alias "My App" and apdex threshold 0.5

Manage recipients

> List all my alert recipients and create a new email recipient for [email protected]

Create a status page

> Create a public status page with checks abc123 and def456, named "My Services Status"

How it works

1. The MCP client sends a tool call to the server via stdio
2. The server authenticates with Updown.io using the X-API-KEY header
3. Requests are sent to https://api.updown.io
4. Responses are formatted as human-readable markdown text and returned
