Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢eu_duty_estimate(lines, consignment_value_eur, channel, date)
Estimate the EU customs duty on a consignment of up to EUR 150 imported under IOSS or by post: EUR 3 per item from 1 July 2026 until 1 July 2028 (Council Regulation (EU) 2026/382, Delegated Regulation (EU) 2026/1022). Use it for questions like "what duty applies to these order lines?", "how many items does this parcel count as?". Pass lines (description, origin, qty, unit_value_eur, optional hs_code) and channel (ioss or postal); optional consignment_value_eur and date. Lines must not carry customer fields. Returns the item count as given and with identical lines merged, the duty for each, the legal basis, and the assumptions. Consignments over EUR 150 and dates outside the period return no duty and say why.

}🟢customs_data_gap_check(csv)
Check the text of a Shopify Inventory CSV (it holds HS Code and COO, country of origin) or product CSV for missing or malformed HS codes, countries of origin, item identifiers (SKU or barcode) and invalid barcodes. Use it for "which products have no HS code?", "is my export ready for customs?". Pass the csv text exactly as exported, up to 2 MB. Returns counts (null where the file has no such column), up to 200 rows with the problem on each, and notes on columns the file lacks. Nothing is stored: the input is used for this answer and dropped.

}🟢bulk_hs_candidates(products, markets)
Suggest candidate tariff (HS) codes for up to 20 product titles from the UK Trade Tariff and, if asked, the US Harmonized Tariff Schedule. Use it for "what HS code could this product use?". Pass products (title, optional description) and optional markets (UK, US). Returns up to 3 candidates per product and market with code, description and source. Every code is a candidate, not binding; a large list may be cut short and says so per product.

}🟢landed_cost_estimate(hs_code, destination, goods_value, shipping, origin, ...)
Estimate the duty, VAT and total landed cost of an item shipped to the UK, US or EU from a tariff line. Use it for "what will import duty and VAT be on this?". Pass hs_code (a full tariff line, a candidate, not binding), destination (UK, US, EU), goods_value and shipping in one currency; optional origin, and country (member state) for EU VAT. UK and US duty rates are read from the official tariffs; EU duty is not looked up. Returns duty, VAT and total with the rate, basis, sources and date. A rate that is not a plain percentage is returned as text with no amount. US chapter 99 additional duties are not included.

}🟡submit_feedback(kind, message, tool)
Send feedback to the maintainers about a missing tool, broken links, a bug, or stale data. Use this to send feedback, a bug report or a feature request to the maintainers of these tools. Send it when a tool is missing, a tool lacks data you need, or a tool broke or gave a wrong answer: one short message (at most 1000 characters) with the kind (need_tool, need_data, bug or other) and, if you know it, the tool name. Returns a ticket id. Feedback is for these tools only: it is not a chat, and nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.
