Tariffmonitor Mcp

Gives Claude two tools to query live US import tariffs across 19,856 HTS codes: lookup_hts_code searches by description or prefix, and calculate_tariff returns the full stacked rate (MFN base plus Section 301, IEEPA, and reciprocal tariffs) with projections for the November 10, 2026 rate cliff. Pass an annual import value and it computes dollar impact before and after the cliff. Hits a free public API at adcreator-ai.com with no authentication. Useful if you're modeling supply chain costs, advising importers, or need to answer "what will this product cost to bring in from China next year" without opening a spreadsheet.
