Whose server it is
  • Registry namecom.dotsweep/dotsweepverified in the MCP registry

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

On 2026-10-21 the server answered initialize and tools/list without a sign-in. First answer in 24 ms.

Should an agent connect itNot proven either way yet
  • Its tools do every use case we checked: check availability of a name across every domain extension; compare renewal prices before registering a domain; look up the registry record for a domain.
  • Checked on 1 of the 7 days it takes to judge reliability.

Once connected

  • For "check availability of a name across every domain extension", the likely first call is check_domains.
  • For "compare renewal prices before registering a domain", the likely first call is check_domains.
  • For "look up the registry record for a domain", the likely first call is whois.

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.

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

None of the five warning signs in these definitions.

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_domains

    Checks whether domain names are available, with registration and renewal prices. Answers come from the registry itself: DNS delegation first, then RDAP, with a WHOIS fallback for the registries that publish no RDAP service. A registry…

  • whois

    Registry record for one domain: registrar, registration and expiry dates, nameservers, status codes, and whether it appears to be for sale. Resolves the correct registry host for the extension itself, and reads RDAP for .dev, .app and…

  • list_tlds

    Every extension this server can check, with registration and renewal price, minimum registration term, and any eligibility restriction on who may register it. Use before check_domains when the extensions to check are not already decided…

  • watch_domain

    Register a watch on a domain that is currently taken, and be emailed once — and only once — when the registry confirms it has become registrable. Use when someone wants a name that is already owned, or asks to be told when one expires or…

How to connect

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

{
  "mcpServers": {
    "dotsweep": {
      "type": "http",
      "url": "https://dotsweep.com/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

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

Add to CursorAdd to VS Code

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