Potal

Connects Claude to Potal's total landed cost API for calculating duties, taxes, and fees in cross-border commerce scenarios. You get access to tariff data across 240 countries with 113 million records backing the calculations. Reach for this when you're building e-commerce tools that need accurate import cost estimates, working on international shipping calculators, or analyzing trade scenarios where knowing the full delivered price matters. The source repository appears to be a Next.js frontend project, so the actual MCP server implementation wraps their existing API endpoints for tariff lookups and landed cost calculations through stdio transport.
