Whose server it is
  • Registry nameio.ohsnap/mcpverified in the MCP registry

The registry name sits under ohsnap.io. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-19 the server answered initialize and tools/list without a sign-in. First answer in 175 ms.

  • Whether its tools do the product's job has not been judged yet.
  • Checked on 2 of the 7 days it takes to judge reliability.

Once connected

  • Keep approval on for send_test_alert: they delete, send or pay without saying so.
  • add_monitor, send_test_alert change data without a sign-in: anyone with the address can call them.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Worth a look

  • Tools that delete, send or pay without telling the client so: send_test_alert
  • Tools that change data, on a server that answers without a sign-in: add_monitor, send_test_alert

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • check_website

    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…

  • 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

    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…

  • get_incidents

    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

    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.

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "ohsnap": {
      "type": "http",
      "url": "https://mcp.ohsnap.io/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http ohsnap https://mcp.ohsnap.io/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://mcp.ohsnap.io/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
