Tools
| Tool | Description | Behaviour |
|---|---|---|
| check_availability | Check if a specific subdomain name is available for registration under a given domain. Returns true if the name is free to claim. | Not declared |
| create_subdomain | 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. | Not declared |
| create_txt_record | 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. | Not declared |
| delete_subdomain | Permanently delete a subdomain DNS record you own. The subdomain will stop resolving immediately. | Not declared |
| delete_txt_record | Delete a TXT verification record from a subdomain you own. | Not declared |
| extend_subdomain | 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. | Not declared |
| list_domains | 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. | Not declared |
| list_subdomains | 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. | Not declared |
| renew_subdomain | 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. | Not declared |
| update_subdomain | 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. | Not declared |
