## Tools
- screen_wallet - Sanctions screening for a crypto wallet address. Checks an EVM address against the Chainalysis on-chain sanctions oracle, which covers OFAC SDN, EU, and UN designated addresses (including Tornado Cash and other sanctioned protocols). Returns a clear sanctioned / not-sanctioned result with the matching program. Use for AML compliance, counterparty due diligence, and payment screening before sending USDC or any funds to an address. Endpoint: https://mcp.onchaindiligence.com/mcp
- screen_name - OFAC name screening: fuzzy-match a person or company name against the official US Treasury OFAC Specially Designated Nationals (SDN) list (primary names + strong aliases). Returns scored candidate matches with the matched name, SDN type, and program. SCOPE: this is a screening aid for AML / KYC / sanctions compliance — a match is a candidate to investigate with secondary identifiers (DOB, nationality, ID), NOT a determination. Weak AKAs are not screened, per OFAC guidance. Endpoint: https://mcp.onchaindiligence.com/mcp
- verify_uk_company - UK company verification and KYB (know-your-business) lookup via the official Companies House register. Given a UK company registration number, returns legal status (active / dissolved), company type, incorporation date, registered office address, and the people with significant control (PSC / beneficial owners). Use for KYB onboarding, supplier and counterparty due diligence, and confirming a UK business is real, active, and who controls it. Authoritative UK government open data. Endpoint: https://mcp.onchaindiligence.com/mcp
- verify_us_company - US public company verification via the SEC EDGAR system. Given a ticker, SEC CIK, or company name, returns the registered entity name, CIK, industry (SIC code), state of incorporation, listed exchanges and tickers, business address, and most recent SEC filing. SCOPE: EDGAR covers SEC-registered PUBLIC companies and funds only — NOT private US companies, which register at the state level. Use for KYB and counterparty due diligence on listed US entities. Authoritative US government open data. Endpoint: https://mcp.onchaindiligence.com/mcp
- diligence - Combined counterparty due diligence in one call: runs sanctions screening on a crypto wallet (Chainalysis oracle — OFAC SDN, EU, UN) AND a UK Companies House KYB lookup (status, type, PSC / beneficial owners) in parallel. Built for compliance agents vetting a counterparty that has both an on-chain wallet and a UK company. Returns both independent results, plus an explicit disclaimer that no verified link between the wallet and the company is established by the data. Endpoint: https://mcp.onchaindiligence.com/mcp
