us-tariff-ledger
MCP serverDev toolsThis integration gives your AI access to US tariff and trade data, including duties actually paid by country of origin and product code since 2017, the HTS rulebook, and CBP rulings. Once added, your AI can look up real duty amounts and trade rules when you ask about imports, tariffs, or product classifications. No API key is needed to use it.

After adding it, ask your AI a question about tariffs or duties on a product you import, such as what duty applies to a given country of origin. Your AI will pull the answer from the tariff ledger and CBP rulings.
What your AI can do with it
- Look up duties actually paid by country of origin and product code since 2017
- Search the HTS rulebook for tariff classifications
- Find CBP rulings related to specific products
- Answer questions about US tariff costs for imported goods
Install us-tariff-ledger
The server’s own address, for the clients that take one directly. Or connect Ahel once and every client you use reads it from one address, with the account kept on Ahel rather than in each client’s config.
Claude Code

From the project's README
As published by mrsingh86/trimtab-ais in README.md. This repository publishes several servers, so only the opening is shown here.
What US importers actually paid at the border — free, no API key, no signup. Official duty receipts by product and origin, monthly since 2017, reconciled monthly against the US Treasury's own customs receipts (both books: assessed at entry and kept after refunds — May and June 2026 ran negative). Plus the current HTS rulebook with Federal Register citations, CBP classification rulings, HS code search, US containerised imports by origin × commodity × gateway (revision-tracked), and a frozen 2026 archive of own-recorded AIS ship movements. Every response carries its method, its provenance, and its limits, so your agent can verify instead of trust.
Published by Trimtabist — the independent observatory for US trade. 20 pre-registered ruled studies (nulls published), a public corrections log, and the whole collection pipeline open at trimtab-pipeline.
