Can't be undone 1Sends, pays, publishes or merges: once done, it cannot be taken back.Claude Code: ask

submit_feedbackSend feedback, a bug report or a tool request to the maintainers of the tools on this server: a missing tool, missing or stale data, or a tool that broke or gave a wrong answer.No findings
Why it is in this group
- The name "submit_feedback" says "submit": a word for a change.
- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
Description, as the server wrote it
Send feedback, a bug report or a tool request to the maintainers of the tools on this server: a missing tool, missing or stale data, or a tool that broke or gave a wrong answer. Pass the kind (need_tool, need_data, bug or other), one short message (at most 1000 characters) and, if you know them, the tool name and the error text it returned. Returns a ticket id. Feedback is not a chat: nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.

Changes things 3Creates or changes something that can be changed back.Claude Code: ask

customs_data_gap_checkBest for: "which products have no HS code?" or "run a customs readiness check on this".No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Best for: "which products have no HS code?" or "run a customs readiness check on this". Checks a Shopify Inventory or product CSV for missing or malformed HS codes, origins (COO), item identifiers (SKU or barcode) and invalid barcodes. Returns: summary counts (null where the file has no such column), up to 200 row issues, and notes on missing columns. Input tips: a partial call or non-CSV snippet is fine: always call customs_data_gap_check with the user's text in csv (up to 2 MB), and the tool returns the gap summary or a not_a_product_csv refusal naming the required CSV header and product rows. Not for: suggesting missing HS codes (use bulk_hs_candidates). Nothing is stored: the input is used for this answer and dropped.

eu_duty_estimateBest for: the EUR 3 per item EU customs duty on a consignment up to EUR 150 under IOSS or post, 2026-07-01 to 2028-07-01 (Reg.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Best for: the EUR 3 per item EU customs duty on a consignment up to EUR 150 under IOSS or post, 2026-07-01 to 2028-07-01 (Reg. (EU) 2026/382, 2026/1022). Covers only channel "ioss" or "postal" (courier outside IOSS is not covered; if asked about a courier like DHL without IOSS, call with "ioss" and state courier outside IOSS is not covered). Returns: item count as given (1 tariff item = EUR 3 per order line, regardless of qty units) and with identical lines merged, duty_eur, legal_basis and assumptions. Over EUR 150 or outside the window, duty_eur is null. Input tips: lines (1-200) of {description, origin (2 letters), qty, unit_value_eur, optional hs_code} and channel ("ioss" or "postal"), optional consignment_value_eur and date. Never send customer fields.

landed_cost_estimateBest for: "what will import duty and VAT be on this?" for one item shipped to the UK, US or EU from a known tariff line.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Best for: "what will import duty and VAT be on this?" for one item shipped to the UK, US or EU from a known tariff line. Returns: duty (general rate plus US chapter 99 duties when origin is given), VAT, US fees (MPF, HMF) and total in the input currency, plus chapter_99, chapter_99_skipped, complete, missing, sources and notes. Input tips: pass hs_code (full line: UK 10 digits, US 8 or 10; if given a 4 or 6 digit heading, still call to get the code_not_final child lines), destination ("UK", "US" or "EU"), goods_value and shipping. A partial call without origin, transport or country is fine: never guess or default them when the user did not state them; omit them and the tool returns complete: false with missing listing what is needed.

Only reads 2Looks things up and changes nothing.Claude Code: allow

bulk_hs_candidatesFind candidate tariff codes for products.No findings
Why it is in this group
- The description's first verb is "find": a word for reading.
Description, as the server wrote it
Find candidate tariff codes for products. Best for: "what HS code could this product use?" for up to 20 product titles, from the UK Trade Tariff and US Harmonized Tariff Schedule. Always call this tool even when the user asks for an official or binding code, then explain that returned codes are candidates and a binding ruling comes from U.S. CBP (eRuling), UK HMRC (Advance Tariff Ruling), or a licensed customs broker. Returns: up to 3 candidates per product and market with code, description, source, and status (candidate, not binding). Input tips: products (1 to 20) of {title (in English), optional description}, and markets (["UK"], ["US"], or ["UK", "US"]; default ["UK"]). Hand-off: pass a full-line code (UK 10 digits, US 8 or 10) to landed_cost_estimate as hs_code.

Why it is in this group

Description, as the server wrote it

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Anlyon alternative

4 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
