Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tool inventory
Tools (6)
🟢check_website(url)
One-off check of whether a website is up right now, from OhSnap's probe network. Works without an account. Use when the user asks "is my site down?", "is X up?", or wants a status code, response time, or the reason a site fails (DNS failure, SSL error, timeout, HTTP error, Cloudflare edge error). Results are cached for 60 seconds per site, and each user can run 10 checks per minute.

}🟢whoami
Returns the OhSnap account this MCP key belongs to: email, plan (Free, Unlimited, Agency), the monitor cap, and the fastest allowed check interval. Call before add_monitor to explain plan limits up front.

}🟢list_monitors
Lists every website this OhSnap account monitors, with its current status (up, down, warning, pending), last response time, and check interval. Use to answer "are my sites up?" and to find a website_id for other tools.

}🟡add_monitor(url, name, check_frequency_seconds, alert_email)
Adds a website to OhSnap so it is checked around the clock and the user is alerted when it goes down or comes back. Free accounts can monitor 5 sites every 5 minutes; Unlimited allows any number every 30 seconds. Pass alert_email if the account has no alert channel yet, otherwise the monitor will run silently. SMS, WhatsApp, Slack and Telegram alerts are configured in the OhSnap dashboard.

}🟢get_incidents(website_id, days, limit)
Returns recent outages for one monitored website: when each started and ended, how long it lasted, and the error. On the Unlimited plan each incident includes an AI diagnosis in plain language; on Free it is marked ai_locked.

}🟡send_test_alert(website_id)
Sends a clearly labelled test DOWN alert through every alert channel linked to a monitor (email, SMS, WhatsApp, Slack, Telegram), so the user can confirm alerts reach them. Limited to one test per monitor per minute.
