## 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 2026-11-05.

- **Endpoint Security**: 74/100
  - 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.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 73/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 695 tokens (~115/item across 6 items; 6 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% 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 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 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).

## MCP tools (6)

### `domain_lookup` (~144 tokens)

Full domain lookup

Full report on a domain in one call: WHOIS/RDAP registration, DNS records, live SSL
    certificate, subdomains (live hosts with IPs first) and email authentication (SPF, DMARC, DKIM).
    Use it to triage a suspicious domain or profile a company's domain. If one section fails it comes
    back as an object with an `error` field and the rest is unaffected. Set wait=true to wait for every
    subdomain source (up to about 20 s) instead of the fast first result.

Input parameters:

- `domain` (string, required)
- `subdomain_limit` (integer)
- `wait` (boolean)

### `whois_lookup` (~89 tokens)

WHOIS / RDAP lookup

Registration data for a domain: registrar, created, updated and expiry dates, nameservers and
    status. RDAP first (rdap.org, IANA bootstrap, 22 fallback servers), then port-43 WHOIS for 60+
    TLDs. `_source` says which one answered. Use it for domain age, expiry or registrar checks.

Input parameters:

- `domain` (string, required)

### `dns_records` (~42 tokens)

DNS records

DNS records for a domain: A, AAAA, MX, TXT, NS, CAA and SOA, resolved in parallel.

Input parameters:

- `domain` (string, required)

### `ssl_certificate` (~56 tokens)

SSL certificate

The certificate a domain serves on port 443, from a live TLS handshake: issuer, subject,
    valid_from, valid_to, days_until_expiry, SANs, signature algorithm and serial number.

Input parameters:

- `domain` (string, required)

### `subdomains` (~121 tokens)

Subdomains

Subdomains of a domain from certificate transparency logs, passive DNS and DNS brute force.
    `live` lists hosts that resolve now, each with its IP; `subdomains` lists every name found, live
    first; `pools` summarises large shared-infrastructure zones. The first lookup of a domain is a fast
    snapshot and later ones are fuller; set wait=true to wait for every source (up to about 20 s).

Input parameters:

- `domain` (string, required)
- `limit` (integer)
- `wait` (boolean)

### `email_security` (~65 tokens)

Email security (SPF, DMARC, DKIM)

Email authentication for a domain: SPF and DMARC records, and DKIM keys found by probing about
    29 common selectors (Google, Microsoft 365, Mailchimp, SendGrid and others). Custom selectors
    may not be found.

Input parameters:

- `domain` (string, required)

## Common questions

### What is the Domain Intelligence MCP server?

Domain Intelligence is an MCP server listed in the public MCP registry as com.oti-labs/domain-intelligence. WHOIS/RDAP, DNS, SSL, live subdomains with IPs, and SPF/DMARC/DKIM for any domain. This page covers its hosted endpoint (https://oti-labs.com/mcp).

### Is the Domain Intelligence MCP server safe to use?

Domain Intelligence scores 82 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Domain Intelligence MCP server expose?

Domain Intelligence exposes 6 tools: domain_lookup, whois_lookup, dns_records, ssl_certificate, subdomains, email_security. Their descriptions and schemas cost roughly 517 tokens of context every time the server is loaded.

### Does the Domain Intelligence MCP server require authentication?

No. We connected to Domain Intelligence without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Domain Intelligence MCP server still maintained?

Domain Intelligence is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
