Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

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.

domainstring, required

Root domain (e.g. 'sitey.my')

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.

Argument	Type	Description
type*	string	Record type. REDIRECT answers every visit with a 301 to the URL in value.
value*	string	Record value: an IPv4 address for A, a hostname for CNAME, an absolute https:// URL for REDIRECT (http:// is refused, and so is a URL under one of this service's own roots).
domain*	string	Root domain (e.g. 'sitey.my')
subdomain*	string	Subdomain name (e.g. 'demo')
owner_token	string	The owner token you were given when you created the record (starts with anon_). Omit it only if you have an API key, or if the record predates tokens and was claimed from this same IP address. Creating without one mints a new one and returns it once.

    }
  }
}

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.

Argument	Type	Description
value*	string	TXT record value (the verification token)
domain*	string	Root domain (e.g. 'sitey.my')
subdomain*	string	Subdomain name (e.g. 'demo')
root_level	boolean	No longer supported — TXT records are always written at the root domain. Passing true returns an error.
host_prefix*	string	TXT record host prefix (e.g. '_vercel' for Vercel verification)
owner_token	string	The owner token you were given when you created the record (starts with anon_). Omit it only if you have an API key, or if the record predates tokens and was claimed from this same IP address. Creating without one mints a new one and returns it once.

delete_subdomain

Permanently delete a subdomain DNS record you own. The subdomain will stop resolving immediately.

Argument	Type	Description
domain*	string	Root domain (e.g. 'sitey.my')
subdomain*	string	Subdomain name (e.g. 'demo')
owner_token	string	The owner token you were given when you created the record (starts with anon_). Omit it only if you have an API key, or if the record predates tokens and was claimed from this same IP address. Creating without one mints a new one and returns it once.

host_prefix*	string	TXT record host prefix (e.g. '_vercel')

}

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.

Argument	Type	Description
domain*	string	Root domain (e.g. 'sitey.my')
payment	string	The x402 payment payload, base64 — the X-PAYMENT header value. Omit to be told what to pay.
subdomain*	string	Subdomain name (e.g. 'demo')
owner_token	string	The owner token you were given when you created the record (starts with anon_). Omit it only if you have an API key, or if the record predates tokens and was claimed from this same IP address. Creating without one mints a new one and returns it once.

    }
  }
}

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.

No arguments.

Input schema (JSON)

{
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "properties": {}
}

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.

Argument	Type	Description
owner_token	string	The owner token you were given when you created the record (starts with anon_). Omit it only if you have an API key, or if the record predates tokens and was claimed from this same IP address. Creating without one mints a new one and returns it once.

Input schema (JSON)

{
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "properties": {
    "owner_token": {
      "type": "string",
      "description": "The owner token you were given when you created the record (starts with anon_). Omit it only if you have an API key, or if the record predates tokens and was claimed from this same IP address. Creating without one mints a new one and returns it once."
    }
  }
}

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.

Argument	Type	Description
domain*	string	Root domain (e.g. 'sitey.my')
subdomain*	string	Subdomain name (e.g. 'demo')
owner_token	string	The owner token you were given when you created the record (starts with anon_). Omit it only if you have an API key, or if the record predates tokens and was claimed from this same IP address. Creating without one mints a new one and returns it once.

    }
  }
}

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.

Argument	Type	Description
value*	string	New record value
domain*	string	Root domain (e.g. 'sitey.my')
subdomain*	string	Subdomain name (e.g. 'demo')
owner_token	string	The owner token you were given when you created the record (starts with anon_). Omit it only if you have an API key, or if the record predates tokens and was claimed from this same IP address. Creating without one mints a new one and returns it once.
