Which MCP servers are whoisbrowsing's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry namecom.whoisbrowsing/mcpverified in the MCP registry

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

Worth a look

  • Tools that change data, on a server that answers without a sign-in: create_site

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 (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). 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 →

  • create_site

    Creates a whoisbrowsing site with no sign-up and returns its script tag (snippet), one watch link per website, a one-time claim link, a terms sentence for the human and the next steps. Call it once per project; one site can hold several…

  • get_install_instructions

    Returns the install guide (Markdown) for one platform: where the script tag goes, a Content-Security-Policy note and how to verify. Call it without a platform, or with an unknown one, to get the list of platforms.

  • check_live

    Asks the live server whether the site's script is connected right now: the websites with a visitor, how many visitors, and which websites the owner is watching. Needs the site's owner key, the part after #wib= in the watch link…

How to connect

    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http whoisbrowsing https://whoisbrowsing.com/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://whoisbrowsing.com/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.
