## Documentation & README

# tariffmonitor-mcp

MCP server for the **Tariff Exposure Monitor** — a live US import tariff calculator covering 19,856 HTS codes.

Give Claude (or any MCP-compatible AI) the ability to look up real stacked tariff rates and project the **November 10, 2026 cliff** impact on any product.

## What it does

Two tools:

| Tool | What it does |
|---|---|
| `lookup_hts_code` | Search 19,856 HTS codes by description or numeric prefix |
| `calculate_tariff` | Returns stacked rate (base + Section 301 + IEEPA + reciprocal) + Nov 10 cliff projection. Optional: annual import volume → dollar impact |

Example exchange:
```
You: What's the tariff on athletic footwear from China, and how does the cliff change my costs if I import $800k/year?

Claude: [uses calculate_tariff with hts_code="6404.11", origin_country="CN", annual_import_value_usd=800000]
HTS 6404110000 — Footwear with outer soles of rubber/plastics...
Rate stack:
  Base rate (MFN): +20.00%
  Section 301 (List 4A): +7.50%
  IEEPA emergency tariff: +145.00%
Total current rate: 172.50%
Nov 10, 2026 cliff: 195.00% (+22.50pp jump)

Dollar impact at $800,000/yr import value:
  Current annual duties: $1,380,000
  Additional after Nov 10 cliff: $180,000/yr
```
