## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 77/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 59/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1755 tokens (~585/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 37/100
  - Stability observed for 11 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

### 2026-10-25 (score 70)

First indexed and scored.

## MCP tools (3)

### `lookup_hts_code` (~282 tokens)

Look up HTS code

Find the US HTS (Harmonized Tariff Schedule) code for a product, by plain-language product name or numeric prefix, from the official USITC schedule (19,856 10-digit codes). Use this first whenever you have a product name rather than a code (e.g. "laptop", "t-shirt", "water bottle", "wireless earbuds", "toys", "e-bike", "running shoes"), then pass a code to calculate_tariff or compare_origins. Everyday shopping words that a plain search of the schedule misses are mapped to the official heading that covers them (e.g. laptop -> 8471.30 "Portable automatic data processing machines"), and the answer names that heading; when a word commonly falls under more than one heading (water bottle: 7323.93 stainless, 9617.00 vacuum flasks, 3924.10 plastic) each is listed, with the 10-digit lines ranked by match to the query. Otherwise descriptions are matched as one phrase; if a phrase matches nothing the tool retries single words and says which word it used. Returns up to 12 codes.

Input parameters:

- `query` (string, required): Product keyword (e.g. "footwear") or HTS code prefix (e.g. "6404"). Minimum 2 characters. Single keywords match best.

### `calculate_tariff` (~903 tokens)

Calculate US import tariff

Calculate the full stacked US import tariff rate for an HTS code from a specific origin country. Returns: base rate, each additional layer (China Section 301 matched by HTS line to Lists 1, 2, 3, 4A and the 2024 four-year-review increases; Section 232 steel, aluminum and copper matched by HTS line to the U.S. note 16 lists, headings 9903.82.02-.26: 50% on listed metal articles, 25% on listed derivatives, UK and 15%-floor rates, with the metal-content conditions stated; other Section 232 programs (vehicles and parts, wood products, trucks, semiconductors, drones) flagged as needs review when the line is named, not computed; Section 301 Brazil, 25% since 22 Jul 2026, heading 9903.05.01, with its exemption lists; and the 2026 Section 301 forced-labor tariff on 60 economies: 10% or 12.5% by origin, or a 10%/12.5% cap net of MFN for the EU, Taiwan, Japan, South Korea and Switzerland, in effect since 24 Jul 2026, FR Doc. 2026-15181, HTS 9903.05.20-9903.05.84), the total current rate, the date the data was checked, and notes naming each exemption or assumption (Section 232 goods, USMCA- or CAFTA-DR-qualifying entries, listed products). For products of Canada it notes that Section 338 duties may apply; their product lists are published only as images, so they are not computed. Also states when the Section 301 China product exclusions end, in both official wordings: through 11:59 p.m. EDT on November 9, 2026 (Federal Register, FR Doc. 2025-21671), which USTR's 26 Nov 2025 press release gives as "until November 10, 2026". Rates are effective-date aware: pass date (YYYY-MM-DD) for the rule in force on that entry date. For products of China it applies the 178 Section 301 product exclusions by statistical number (U.S. note 20(vvv)/(www)) through their end date, and the maritime Section 301 headings (9903.92.10 +25% on ship-to-shore cranes; from 10 Nov 2026 9903.91.14 +100% on those cranes and 9903.91.12 +100% on intermodal chassis, shown as "up to" because chapter 99 does not s…

Input parameters:

- `annual_import_value_usd` (number): Optional. Your annual import value in USD. If provided, the response includes the dollar cost of current duties and any additional cost once the Section 301 China exclusions end (after 11:59 p.m. EDT…
- `date` (string): Optional. Entry date YYYY-MM-DD; the rate in force on that date is returned (e.g. "2026-11-09" vs "2026-11-10" to see the Section 301 exclusion end and the maritime duties). Default: today in US East…
- `hts_code` (string, required): HTS code — at least 6 digits, up to 10 (e.g. "6404.11" or "6404112030"). Dots and spaces are ignored. Zero-padded headings such as "6404110000" are not real schedule codes; if the exact code is not f…
- `origin_country` (string): ISO-2 origin country code (e.g. "CN" for China, "VN" for Vietnam, "MX" for Mexico). Default: CN.

### `compare_origins` (~384 tokens)

Compare tariffs by origin country

Compare the estimated US import tariff for ONE HTS code across several origin countries side by side (e.g. China vs Vietnam vs Mexico vs India), for sourcing and "China plus one" decisions. For each origin returns the total current rate, the layers that make it up (MFN base, Section 301 China, Section 232 by HTS line, Section 301 Brazil, 2026 Section 301 forced-labor tariff) and the rate after the Section 301 China exclusions end (through 11:59 p.m. EDT on 9 Nov 2026 per the Federal Register, FR Doc. 2025-21671; USTR's press release says until 10 Nov 2026), sorted lowest first, with the dollar duty when an annual import value is given. Estimates only; preferential rates (USMCA, FTAs) depend on rules of origin and are not assumed.

Input parameters:

- `annual_import_value_usd` (number): Optional. Annual import value in USD; adds the estimated annual duty for each origin.
- `date` (string): Optional. Entry date YYYY-MM-DD; the rate in force on that date is returned (e.g. "2026-11-09" vs "2026-11-10" to see the Section 301 exclusion end and the maritime duties). Default: today in US East…
- `hts_code` (string, required): HTS code, 6 to 10 digits (e.g. "8471.30" or "6404112030"). Use lookup_hts_code first if you only have a product name.
- `origin_countries` (array): ISO-2 origin country codes to compare, 2 to 8 of them (e.g. ["CN","VN","MX","IN"]). Default: CN, VN, MX, IN, TH.
