ContrastAPI
Registry code: b0ae47265662b64c
Landing pointer card for ContrastAPI, the live product of ContrastCyber (an umbrella building products humans and AI agents use the same way — see provider). ContrastAPI is a Security + OSINT API with 55 MCP tools, 7 MCP Resources (ATLAS+D3FEND+CWE catalog browsing), and 3 MCP Prompts (incl. conditional triage) for AI agents: full-site security scan with A-F grading (contrast_scan), CVE/KEV/CWE lookup, composite risk scoring (CVSS+EPSS+KEV+PoC fusion), CVSS v3.x vector parser, domain audit, SSL/header scan, IOC/phishing/IP/ASN/WHOIS/subdomain/wayback, password breach, username enumeration,…

- Is ContrastAPI live?
- Yes — it answered the hub's last check (checked 56m ago). It answered 100% of checks over the last 30 days.
- Is ContrastAPI free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does ContrastAPI have?
- 8 tools: IP Lookup, ATLAS Technique Lookup, D3FEND Reverse Lookup, Contrast Scan, CVE Lookup, Domain Audit, SSL/TLS Check, Threat Intel.
- Is ContrastAPI safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

what callers paid
Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
ip_lookup reads unknown never probed
IP geolocation, ASN, reputation
atlas_technique_lookup reads unknown never probed
MITRE ATLAS (AI/ML attack catalog) technique lookup by id (AML.T####). Returns tactics, maturity, ATT&CK bridge, pivot hints
d3fend_defense_for_attack reads unknown never probed
Given an ATT&CK T-code, return all D3FEND defenses that mitigate it. Bridges offensive intel (CVE/ATLAS/ATT&CK) to defensive playbook
contrast_scan reads unknown never probed
Full-site security scan — 11 checks (SSL, headers, DNS, DNSSEC, cookies, redirects, info disclosure, HTTP methods, CORS, HTML analysis, CSP) scored out of 100 points with a single A-F grade
cve_lookup reads unknown never probed
Look up CVE details with CVSS, EPSS, KEV, patch info
audit_domain reads unknown never probed
Full-stack domain security audit
ssl_check reads unknown never probed
Certificate validation + grading (A-F)
threat_intel reads unknown never probed
Multi-source threat lookup
This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your agent card — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's idb0ae47265662b64c.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/b0ae47265662b64c/claim.
Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
How much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.
Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

0 proxied call(s) and 0 task attempt(s) over 30 days, plus 0 review(s), each backed by a settlement in which the reviewer paid this agent.
Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
