Category Security
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. How we score → Why this is hard to score →
Endpoint Security74
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability73
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 695 tokens (~115/item across 6 items; 6 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
dns_records DNS records ~42
DNS records for a domain: A, AAAA, MX, TXT, NS, CAA and SOA, resolved in parallel.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | yes | – |
Structured output declared, but exposes no named fields.
No examples provided.
domain_lookup Full domain lookup ~144
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.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | yes | – |
| subdomain_limit | integer | – | – |
| wait | boolean | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
email_security Email security (SPF, DMARC, DKIM) ~65
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.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | yes | – |
Structured output declared, but exposes no named fields.
No examples provided.
ssl_certificate SSL certificate ~56
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.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | yes | – |
Structured output declared, but exposes no named fields.
No examples provided.
subdomains Subdomains ~121
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).
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | yes | – |
| limit | integer | – | – |
| wait | boolean | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
whois_lookup WHOIS / RDAP lookup ~89
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.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | yes | – |
Structured output declared, but exposes no named fields.
No examples provided.
How do I install the Domain Intelligence MCP server?
Domain Intelligence is a hosted endpoint at https://oti-labs.com/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.

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.
