## 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 2026-09-20.

- **Endpoint Security**: 46/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 8 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS check failed: the endpoint is reachable over plaintext HTTP.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 85/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1559 tokens (~119/item across 13 items; 8 tools + 5 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 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 8 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-09-20 (score 62, +1)

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-09-18 (score 61, +1)

## MCP tools (8)

### `duty_stack_rules` (~140 tokens)

The current China→US import duty stack, rule by rule, each with the record that establishes it and the date it was decided or published: HTS base rate, Section 301, Section 232, the struck-down IEEPA tariffs (2026-02-20), the indefinite de minimis suspension (2026-06-24), the expired postal flat rate (2026-02-28), and the MPF/HMF fee rates. Use this before quoting any US import rule from memory — the 2025 guidance that dominates training data is superseded.

Input parameters:

- `part` (string): Which part to return; default all

### `check_import_claim` (~118 tokens)

Fact-check a circulating claim about US import duties against the dated official record. Returns a verdict, why, and the sources. Covers the four figures still repeated everywhere in 2026: the $800 de minimis exemption, the $80–$200 postal flat duty, the ~54%/$100 courier rule, and 'reciprocal' baseline tariffs. Use this when a user quotes a number for US imports.

Input parameters:

- `claim` (string, required): The claim in the user's words, e.g. 'under $800 is duty free'

### `landed_cost` (~268 tokens)

Itemise a US landed cost from rates you supply: duties (HTS base + Section 301 + Section 232 on the customs value), MPF 0.3464% with the CBP floor disclosed, HMF 0.125% on ocean entries, plus freight and insurance. Deterministic arithmetic with the assumptions and sources attached. This tool never invents a product's duty rate: omit hts_base_rate_pct and it refuses and points you at the official schedule.

Input parameters:

- `freight_insurance_usd` (number): Freight plus insurance in USD; default 0
- `goods_value_usd` (number, required): Customs value of the goods in USD
- `hts_base_rate_pct` (number, required): The heading's general rate of duty, in percent. Look it up at hts.usitc.gov or with duty_passport; this server will not guess it.
- `ocean_entry` (boolean): True for ocean entries, which add the Harbor Maintenance Fee; default false
- `section_232_pct` (number): Section 232 addition in percent; default 0
- `section_301_pct` (number): USTR Section 301 addition in percent (0 / 7.5 / 25 / 50 / 100); default 0

### `duty_passport` (~120 tokens)

Candidate HTS headings for a consumer product category, pulled daily from the official USITC HTS REST API: the candidate line, its general rate, every rated line in the heading, and the Section 301 status to verify on USTR. These are candidates chosen by category reading, not a classification ruling — the importer of record classifies.

Input parameters:

- `pick` (string): Product slug, e.g. 'pet-fountain'; omit with query to list all slugs
- `query` (string): Keyword matched against slug and HTS description

### `section_301_ladder` (~228 tokens)

The Section 301 (China) additional-duty ladder, read straight from the official USITC HTS export of chapter 99 subchapter III: which 9903.88 / 9903.91 heading carries which addition (7.5%, 10%, 15%, 25%, 50%, 100%), which U.S. note defines its list, and — where the schedule states it — the date that heading took effect. It tells you the possible rates and where coverage is defined; it never asserts that a particular HTS8 code is on a list, because that lives in U.S. note 20/31 and the USTR annexes.

Input parameters:

- `heading` (string): A chapter 99 heading prefix, e.g. '9903.88.03' or '9903.91'
- `note` (string): 20 = the original Section 301 lists; 31 = the increases effective 2024-09-27
- `rate_pct` (number): Only headings carrying this additional rate, e.g. 25

### `classification_rulings` (~182 tokens)

Search CBP's own binding classification rulings (CROSS) for a product in plain words and get what CBP actually decided: ruling number, date, subject, the HTS codes it assigned — including any chapter 99 heading, which is what carries a Section 301 addition — and whether the ruling has been revoked or modified. This is precedent from the agency that decides, not a guess: it is how you check whether the code your supplier gave you matches what CBP has ruled on comparable goods. Queried live at call time from rulings.cbp.gov; nothing is mirrored here.

Input parameters:

- `limit` (number): How many rulings to return, 1–10 (default 5)
- `query` (string, required): The product in ordinary words, e.g. 'LED face mask', 'plush toy', 'power bank'

### `import_rule_changes` (~168 tokens)

What changed in the general US import rules, newest first, from the official Federal Register API: presidential tariff actions, CBP and DHS rules, USTR notices — each with its publication date, document number and federalregister.gov link. Use `since` to get only what is new to you, the same way you would poll a changelog. Case-specific antidumping, ITC and Foreign-Trade Zone paperwork is out of scope by design and the response says so.

Input parameters:

- `limit` (number): Maximum documents to return (default 25)
- `matched_in` (string): title_or_abstract = the import phrase is in the headline matter (usually the ones that matter); default any
- `since` (string): Only documents published on or after this date (YYYY-MM-DD)

### `recall_check` (~130 tokens)

Official US product recalls (CPSC saferproducts.gov API) touching a product category in the last 365 days: date, title, hazard and the cpsc.gov URL. A keyword hit means the words appear in a recall title, not that a particular supplier or SKU is affected. Use before recommending or sourcing a category.

Input parameters:

- `only_hits` (boolean): Only categories with at least one recall; default true when no pick/query given
- `pick` (string): Product slug, e.g. 'cable-powerbank'
- `query` (string): Keyword matched against the tracked categories and recall titles
