On 2026-10-29 the server answered initialize and tools/list without a sign-in. First answer in 638 ms.

• Its tools do Host DNS for a domain on its own nameservers; Update a dynamic DNS hostname from a router, but not Register a com, net or org domain paid in bitcoin.
• Checked on 6 of the 7 days it takes to judge reliability.

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.

• Every tool passes all six checks.

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 →

• info

  Free: prices in sats per product and period, nameservers, limits, record types, accepted Cashu mints, how paying works, and the steps to host a zone.

• check

  Free: runs the checks a paid call runs before payment (name rules, availability, delegation, limits) without creating an invoice, and returns the price. For zone_create and secondary_create of a new zone it answers delegation_missing with…

• domain_check

  Free: whether a .com, .net or .org name is available and its price in sats. Tightly rate-limited. Registration itself is not offered through this server.

• zone_create

  Creates a hosted, DNSSEC-signed zone on our nameservers. First call check (tool zone_create): a new zone gets its own nameserver pair, which must be set at the registrar before the payment step; pass the ns_ticket from that answer. The…

• secondary_create

  We serve your zone as secondaries, transferred from your primaries (public IPv4) with a TSIG key that the answer gives once. The same nameserver-pair step as zone_create applies (check first). Paid, no account. Without payment the call…

• hostname_create

  Creates a dynamic hostname such as myhome.dynkite.com. The answer gives the hostname token once (keep it: hostname_update and routers use it). Paid, no account. Without payment the call returns payment_required with the price, a Lightning…

• renew

  Extends a hosted zone, secondary zone or dynamic hostname by 30d or 1y from its current expiry. Needs no token: anyone may pay to extend any name. Paid, no account. Without payment the call returns payment_required with the price, a…

• zone_add_queries

  Adds 1 million queries to a hosted zone's monthly allowance. Paid, no account. Without payment the call returns payment_required with the price, a Lightning invoice and a Cashu payment request; pay only within what your user allowed, then…

• zone_status

  Free: state, expiry, nameservers, delegation and usage of a hosted zone. Pass the zone token (jdz_...) from the create answer, or a scoped account API key (jdk_...) made in the dashboard. Either passes through your model context and…

• records_list

  Free: the zone's rrsets, optionally only one owner name and/or type. Pass the zone token (jdz_...) from the create answer, or a scoped account API key (jdk_...) made in the dashboard. Either passes through your model context and…

• records_change

  Free: applies up to 100 rrset changes at once, all or none. Each item REPLACEs one rrset (name and type) with the given records, or DELETEs it. Deleting records can take a site or mail offline: change only what your user asked for. Pass…

• dnssec_info

  Free: the DS record(s) to enter at the registrar, and what the parent zone publishes now. Pass the zone token (jdz_...) from the create answer, or a scoped account API key (jdk_...) made in the dashboard. Either passes through your model…

• hostname_status

  Free: state, expiry and current records of a dynamic hostname. Pass the hostname token (jdh_...) from the create answer, or a scoped account API key (jdk_...) made in the dashboard. Either passes through your model context and transcript…

• hostname_update

  Free: sets the hostname's A, AAAA, TXT, ACME TXT or HTTPS records; fields left out stay as they are, [] deletes. Give explicit public addresses: the caller's own address ('auto') is not available here, because through MCP it would be your…

• renewal_address

  Free: the Lightning address and LNURL that extend this zone or hostname pro rata when anyone pays it (no token needed to pay). Made once, then the same address is returned. Pass the zone token (jdz_...) from the create answer, or a scoped…

• account_objects

  Free, read-only: the account's state and limits, or the zones, hostnames or invoices it owns. With api_key, only the objects the key's scope covers and only their invoices (the account view of limits and counts is the same for every key)…

• account_order

  Orders a product into your account, paid by its own invoice: Lightning (15 min) or a new on-chain address (orders of 5,000 sats and up). Prices as in info. pay=check runs the free checks only and makes no invoice: use it first. Refused…

• order_status

  Free: the invoice's state (paid, fulfilled, expired, ...) and, after fulfilment, the result. A new object's token (and TSIG key) is shown once, only to a nip98 call, within 1 hour of fulfilment; an api_key sees the state only, and only of…

• claim

  Free: puts a zone or hostname bought with a token into your Nostr account, so you get expiry reminders by DM and can manage it with API keys. If another account owns it, a 72-hour recovery starts instead and that owner is told. Called…

• token_rotate

  Free: makes a new token for a zone or hostname; the old one stops working at once. Use it when a token may have leaked (tokens pass through model context). Authorize with the current token or, for an object in your account, with nip98…
