This one solves a problem I kept running into: agents that approve payments or onboard suppliers with zero counterparty verification.</p> <p>The risk is real. A single payment to a sanctioned entity creates criminal liability. A single fraudulent supplier invoice with no registry check creates unrecoverable financial exposure. Agents don't know this — they just approve.</p> <h2> What I built </h2> <p>Bizfile MCP is a Model Context Protocol server with three tools:</p> <p>validate_counterparty — checks UK Companies House, Singapore ACRA, and OpenCorporates (210M+ companies across 130+ jurisdictions). Returns company status, directors, filing history, AI risk score 0-100, KYC confidence HIGH/MEDIUM/LOW, and a PROCEED/EDD/BLOCK verdict. One call, machine-ready output.</p> <p>screen_counterparty — screens against 328 global sanctions lists including UN, EU, OFAC, UK HMT, and MAS Singapore via OpenSanctions, updated daily. Returns CLEAR/MATCH verdict and matched list names.</p> <p>validate_counterparty_lite — fast registry-only check for high-volume workflows. No AI scoring, sub-second response, lower token cost.</p> <h2> Example </h2> <p>curl -X POST <a href="https://bizfile-mcp-production.up.railway.app" rel="noopener noreferrer">https://bizfile-mcp-production.up.railway.app</a> \<br> -H "Content-Type: application/json" \<br> -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"validate_counterparty","arguments":{"company_name":"ROLLS-ROYCE PLC","country":"GB"}}}'</p> <p>Returns:</p> <p>{<br> "agent_action": "PROCEED",<br> "registered_name": "ROLLS-ROYCE PLC",<br> "registration_number": "01003142",<br> "status": "active",<br> "kyc_confidence": "HIGH",<br> "risk_score": 12,<br> "risk_level": "LOW"<br> }</p> <h2> How to use it </h2> <p>Any MCP-compatible harness works. Smithery install:</p> <p>smithery mcp add OjasKord/bizfile-mcp</p> <p>Or connect directly via HTTP at:<br> <a href="https://bizfile-mcp-production.up.railway.app" rel="noopener noreferrer">https://bizfile-mcp-production.up.railway.app</a></p> <h2> Pricing </h2> <p>Free tier: 20 calls/month, no API key needed.<br> Paid: $0.019/call metered or $20 for 500 calls that never expire.</p> <p>Full docs and all 9 MCP servers at kordagencies.com.</p> ai mcp agents kyc
