Deletes or cancels 2Claude Code: deny
  • delete_subdomainPermanently delete a subdomain DNS record you own.No findings

    Why it is in this group

    • The name "delete_subdomain" says "delete": a word for removing or ending something.
    • The description says "Permanently delete".
    Description, as the server wrote it
    Permanently delete a subdomain DNS record you own. The subdomain will stop resolving immediately.
  • delete_txt_recordDelete a TXT verification record from a subdomain you own.No findings

    Why it is in this group

    • The name "delete_txt_record" says "delete": a word for removing or ending something.
    Description, as the server wrote it
    Delete a TXT verification record from a subdomain you own.
Changes things 6Claude Code: ask
  • check_availabilityCheck if a specific subdomain name is available for registration under a given domain.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Check if a specific subdomain name is available for registration under a given domain. Returns true if the name is free to claim.
  • create_subdomainCreate a new DNS record for a subdomain.No findings

    Why it is in this group

    • The name "create_subdomain" says "create": a word for a change.
    Description, as the server wrote it
    Create a new DNS record for a subdomain. Supports A records (IP address), CNAME records (hostname) and REDIRECT records (an https:// URL — visitors to the name are sent there with a 301). Example: create demo.sitey.my pointing to 1.2.3.4. No account, API key or signup is needed. The target does not have to be serving yet: claim the name first and deploy to it second if that is your order. The result carries reachable:false when nothing answered, and the record is created either way. If you send no owner_token, the result carries a new one under 'owner_token' — save it, it is shown once and is the only way to change or delete this record later. Without an API key, a CNAME or REDIRECT may not point at a temporary tunnel (trycloudflare.com, ngrok and the like), names containing words such as login or wallet are refused with ACCOUNT_REQUIRED, and TXT records are not available.
  • create_txt_recordCreate or update a TXT record for domain verification.No findings

    Why it is in this group

    • The name "create_txt_record" says "create": a word for a change.
    Description, as the server wrote it
    Create or update a TXT record for domain verification. Used for services like Vercel (_vercel) and Netlify that require DNS-based ownership proof. The record is placed at the root domain under the prefix you give (e.g. _vercel.sitey.my), alongside the other owners' values — that is the name Vercel reads for a subdomain of sitey.my. Needs an account: send an API key from the dashboard (Authorization: Bearer styo_…) on the MCP request. Without one this returns ACCOUNT_REQUIRED.
  • extend_subdomainPaying for a year is switched off on this server, so this always answers PAYMENT_DISABLED.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Paying for a year is switched off on this server, so this always answers PAYMENT_DISABLED. Use renew_subdomain, which is free and adds a month.
  • renew_subdomainExtend a subdomain you own before it expires.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Extend a subdomain you own before it expires. Subdomains are lent for a period, not given: agent-created records last one month and user records three. Nothing emails an agent, so read expires_at from list_subdomains and call this before that date. One call resets the clock from today. Renewal only opens in the last two weeks before expires_at — an earlier call is refused and tells you the date it opens.
  • update_subdomainUpdate the DNS record value of a subdomain you own.No findings

    Why it is in this group

    • The name "update_subdomain" says "update": a word for a change.
    Description, as the server wrote it
    Update the DNS record value of a subdomain you own. For example, change the IP address that demo.sitey.my points to. The new target does not have to be serving yet; the result carries reachable:false when nothing answered, and the record is moved either way.
Only reads 2Claude Code: allow
  • list_domainsList available root domains (e.g.No findings

    Why it is in this group

    • The name "list_domains" says "list": a word for reading.
    Description, as the server wrote it
    List available root domains (e.g. sitey.my, sitey.one) that you can create subdomains under. Call this first to know which domains are available.
  • list_subdomainsList all subdomains you own.No findings

    Why it is in this group

    • The name "list_subdomains" says "list": a word for reading.
    Description, as the server wrote it
    List all subdomains you own. Returns subdomain name, domain, record type, value, and creation date. A REDIRECT record also carries hits: how many visits it has answered in total, how many this calendar month, and when the last one was. Filtered by your API key, or by the owner_token you pass, or — for records made before tokens existed — by your IP address.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as subdomains. Review it before you use it.
