## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-17.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 68/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 679 tokens (~169/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 33/100
  - Stability observed for 10 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 88/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 58% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## Install

### How do I install the Hivex: .si names, DNS and WHOIS MCP server?

Hivex: .si names, DNS and WHOIS is a hosted endpoint at https://hivex.si/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (4)

### `find_names` (~191 tokens)

Find .si 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.

Input parameters:

- `limit` (integer)
- `match` (string)
- `max_length` (integer)
- `min_length` (integer)

### `check_name` (~102 tokens)

Check a .si 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.

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.

Input parameters:

- `name` (string, required): A domain, hostname or IP address (e.g. 'example.com', '_dmarc.example.com', '8.8.8.8')

Input parameters:

- `domain` (string, required): A domain, e.g. 'example.com' (a hostname is reduced to its domain)
