## Quality 100/100 (strong)

### protocol: 100 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 3600000)

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 4 of 4 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 829 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: 2 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 4, about 829 tokens to load them all
- tool set hash: 7359d8d07a5128e0a86ca0c82f1c9d12
- tools last changed: 2026-10-11T06:06:27.611Z
- badge: [![protogrid quality](https://protogrid.dev/badge/si.hivex/names.svg)](https://protogrid.dev/servers/si.hivex/names)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-11 `whois_lookup` added
  - Look up the registration record of any domain, live from its registry's RDAP (the successor of WHOIS): whether it is registered, the registrar, creation and expiry dates, status codes and name servers. Personal details of the holder are never returned. Links to the explained record on hivex.si.
- 2026-10-11 `dns_lookup` added
  - Look up the DNS records of any domain or hostname on any extension, live, through Cloudflare's public resolver: A, AAAA, CNAME, MX, NS, TXT, CAA, SOA and more, or the reverse DNS (PTR) of an IP address. Returns the records with their TTLs and the hivex.si page that explains what they mean.

## Tools (4)

- `check_name`: Look up one .si domain name: whether Hivex lists it as free or likely free, whether it is for sale on Hivex, or whether someone registered it, plus a DNS lookup made now. Returns the name's hivex.si page, where the user runs the final live registry check before registering.
- `dns_lookup`: Look up the DNS records of any domain or hostname on any extension, live, through Cloudflare's public resolver: A, AAAA, CNAME, MX, NS, TXT, CAA, SOA and more, or the reverse DNS (PTR) of an IP address. Returns the records with their TTLs and the hivex.si page that explains what they mean.
- `find_names`: Search Hivex's index of .si domain names that are free to register. Filter by a word or fragment (contains, starts with, ends with, exact), length and minimum score; sort by best score, newest or shortest. Returns up to 25 names, each with its hivex.si page.
- `whois_lookup`: Look up the registration record of any domain, live from its registry's RDAP (the successor of WHOIS): whether it is registered, the registrar, creation and expiry dates, status codes and name servers. Personal details of the holder are never returned. Links to the explained record on hivex.si.
