DomainSpace MCP server

Which MCP servers are DomainSpace'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 namesi.domainspace/domainspaceverified in the MCP registry

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

On 2026-10-29 the server answered initialize and tools/list without a sign-in. First answer in 70 ms.

Should an agent connect itNot proven either way yet
  • Whether its tools do the product's job has not been judged yet.
  • Checked on 6 of the 7 days it takes to judge reliability.

Once connected

  • For "Point a si domain at a hosting or email provider", the likely first call is list_dns_records.
  • add_dns_record, delete_dns_record 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.

  • not sure · Give an AI agent a readable mailbox on their domain

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

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

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 →

  • check_domain

    Check whether a domain name can be registered and what the first year costs (EUR, VAT included; .si and the other endings the shop sells, each at its own flat price that is the same on renewal). Does not reserve or buy anything. Calls the…

  • list_domains

    List the domains in this account with expiry date, renewal state (open, early, expired, unknown), renewal price and, when the marketplace is open, whether each is listed for sale (read-only: selling is done in the dashboard).

  • delete_dns_record

    Delete DNS records of a domain in this account that match type, name and value (and prio for MX); the TTL need not be given. Irreversible. Use list_dns_records first to see the exact values.

  • start_registration

    Prepare the purchase of one or several domains (up to 10, one year each; .si names and names under the other sold endings can be mixed, each at its own price) in ONE checkout. This does NOT buy anything and creates no order: it checks the…

  • start_renewal

  • list_mailboxes

    List the email mailboxes of this account (address, status, plan, expiry) and whether an agent can read each one now. Reading mail needs the mail:read permission.

  • create_mailbox

How to connect

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

{
  "mcpServers": {
    "domainspace": {
      "type": "http",
      "url": "https://domainspace.si/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http domainspace https://domainspace.si/mcp

Add to CursorAdd to VS Code

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