Professor Sausages — Trust & Verification is an MCP server with 12 tools an agent can call, among them address_screen, domain_intel, email_check. It answers at https://x402.professorsausages.com/mcp/trust over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
Email, phone, domain, URL & OFAC verification; phishing and IBAN checks via x402.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
address_screen | Screen a crypto address against the full live OFAC SDN list, segmented by chain. Returns a verdict with the matching SDN entries as evidence — never a silent all-clear. Paid: call without x_payment to receive this call's exact terms (amount Inputs: chain, address, x_payment |
domain_intel | RDAP registration card for a domain (creation/expiry dates, registrar, statuses, nameservers, DNSSEC) plus derived risk flags like domain age. view='dns' returns a live multi-record DNS summary (A/AAAA/CNAME/MX/NS/TXT/SOA/CAA + SPF/DMARC); Inputs: domain, view, x_payment |
email_check | Deliverability signals for one address: RFC5322 syntax, live MX/SPF/DMARC over DNS-over-HTTPS, disposable/role-account flags. Signals with evidence — not a guaranteed inbox verdict. Paid: call without x_payment to receive this call's exact Inputs: email, x_payment |
find_data | Describe the data you need in plain language (e.g. 'Apple risk factors 2023', 'is this token a honeypot', 'is this email deliverable', 'read this page'). Searches this server's datasets first, then the whole Professor Sausages catalog, and Inputs: task |
iban_check | Validate an IBAN (length + mod-97 check digits). view='decode' resolves it to country, bank and account parts; view='format' returns electronic and paper (grouped) forms. Paid: call without x_payment to receive this call's exact terms (amou Inputs: iban, view, x_payment |
phone_check | Validate and normalize a phone number: E.164 form, line type, region, and a verdict. Pure CPU, no third-party lookup. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with Inputs: number, region, x_payment |
pricing | Every endpoint this server fronts, with its exact per-call USD price (x402, USDC on Base) and a one-line summary, read live from the route table. Free. |
request_data | The suggestion box: ask for data we don't have (a pre-2015 filing, an uncovered ticker, an unsupported chain, a whole dataset). Requests feed the nightly ingestion queue — filings are usually available within ~24h. Include contact if you wa Inputs: description, use_case, contact |
sanctions_entity | The complete OFAC record for one entity number: all aliases, addresses, sanctions programs, and extracted identifiers (passports, tax ids, DOBs). Use after sanctions_screen returns a candidate. Paid: call without x_payment to receive this c Inputs: id, x_payment |
sanctions_screen | Fuzzy-screen a name against the full OFAC SDN + Consolidated lists. Returns match / possible_match / no_match with scored candidates and the aliases that matched — never a silent all-clear. Paid: call without x_payment to receive this call' Inputs: name, type, list, min_score, limit, x_payment |
url_screen | Screen a URL against the URLhaus blocklist snapshot plus deterministic live heuristics (redirect chain, host reputation signals, lookalike patterns). Returns a verdict with the rules that fired. Paid: call without x_payment to receive this Inputs: url, follow, x_payment |
vessel_screen | Screen vessels against OFAC maritime designations by fuzzy name, exact call sign, or IMO number, with flag filtering. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with Inputs: name, call_sign, imo, flag, limit, x_payment |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://x402.professorsausages.com/mcp/trust. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
