What it does
MadTaco is an MCP server that provides verification and screening tools for AI agents, including tax ID validation, sanctions screening, company verification, and domain inspection. It operates on a prepaid credit system where failed checks incur no charges.
- Validate tax IDs, IBANs, email addresses, and phone numbers before processing financial or identity information.
- Screen individuals and companies against sanctions lists and verify company details for compliance checks.
- Inspect domain reputation and perform multi-check screening workflows with a single API call.

Before you enable it
An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
