Tariff & HS Code Duty Finder

https://server.smithery.ai/nguyenhieuec/tariffs/mcp

● healthy

Find an HS code, HTS code or customs code, and read the customs duty or import tax. Ask "what is the tariff code for a ceramic flower pot in the UK?", "what is the US duty on HTS 8507.60.00?" or "what duty applies to code 6914100000 from Vietnam in the UK?". Tariff and HS Code Duty Finder reads the official schedules published by governments: the UK Trade Tariff (HM Revenue & Customs) and the US Harmonized Tariff Schedule (US International Trade Commission). Describe the product and it lists the codes whose descriptions match, with the headings above each one so a line that only says "Other" can be read in context. Give a code and it returns the description, the duty rate and, for the UK, the VAT rate, the preferential rate for the country the goods come from and other measures that apply. People also call it Tariff Code Finder.

MCP readiness

B · 83/100

Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here B, 80.2/100), which weighs availability, conformance, p95 speed and descriptor. How the two differ

Valid MCP handshake	10/10	initialize and tools/list both answered.
Live MCP endpoint	25/25	Endpoint answers the MCP initialize handshake (1334 ms).
Protocol revision	8/10	Speaks MCP 2025-11-25, 1 revision(s) behind 2026-07-28.
Signed descriptor	n/a	No MCP standard defines a signed server descriptor.
Uptime (30 days)	15/15	30/30 probes succeeded over 30 days (100%).
Tool declaration	10/10	Lists 4 tool(s) with descriptions.
Verified identity	5/10	Publisher declared (repository, package or homepage); claim this listing to verify domain control.
Freshness + modern flags	0/5	not seen in a source for over 30 days.
Auth declaration	2/5	Declares credential scheme: smithery_api_key.

Applicable criteria total 90 points, scaled to 100.

Responsiveness: Responsive (1334 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).

Measured 2026-11-11.

Nine criteria, the same as the A2A readiness score, read from our daily MCP probe (initialize + tools/list) and 30-day probe history. No MCP standard defines a signed server descriptor, so that criterion is n/a and the other 90 points are scaled to 100. Grades: A>=90, B>=75, C>=60, D>=40, F<40. Display only: search order uses the quality grade.

Compared with peers

Against 53,021 reachable MCP servers in our daily snapshot (2026-11-12 01:39 UTC). Display only; it does not change search order.

Readiness: Higher than 60% of peers; This listing 83 · peer median 81
Latency: Faster than 32% of peers; This listing 485 ms · peer median 326 ms

Where it loses the most points, and how to win them back

Verified identity −5 — Claim the listing and prove control of its domain.
Now: Publisher declared (repository, package or homepage); claim this listing to verify domain control.
Freshness + modern flags −5 — Keep the listing current in the registry or source it comes from.
Now: not seen in a source for over 30 days.
Auth declaration −3 — State how to authenticate (an auth scheme, or that none is needed).
Now: Declares credential scheme: smithery_api_key.
