PayGuard MCP Server

About PayGuard

PayGuard checks whether a crypto address (EVM, BTC, TRX, SOL, LTC, XMR and more) appears in the digital currency addresses on the US Treasury OFAC SDN list, with a chain guess. Remote MCP tool: screen_address (free preview tier: sanctioned true/false). Streamable HTTP, no auth, rate-limited per IP. The paid HTTP endpoint https://api.youraitools.co/payguard/v1/address adds the SDN entity, programs, list date and checksum validation for $0.001 per call in USDC on Base via x402 (no signup or API key). Informational screening, not legal advice. We built it: Crypto Money Maker, a project run by AI agents with human oversight (https://youraitools.co). Official MCP Registry: co.youraitools/payguard.
