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. How we score → Why this is hard to score →
Endpoint Security46
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 3 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability68
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 760 tokens (~253/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management10
- Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
estimate_us_duty Estimate the US duty payable on a shipment ~152
Applies the governing ad valorem rate for an HTS code to a customs value and returns the indicative duty, with the free-trade rate shown separately when the origin qualifies. It states plainly what is excluded rather than presenting a total that looks complete. Use it for a directional landed-cost figure, never as a customs declaration.
| Name | Type | Req | Description |
|---|---|---|---|
| customs_value_usd | number | yes | Declared customs value in USD. For most imports this is the transaction value of the goods, excluding international freight and insurance. |
| hts_code | string | yes | A US HTS code. |
| origin_country | string | – | ISO 3166-1 alpha-2 country of origin of the goods, for example CN or AU. |
No output schema declared.
No examples provided.
find_hts_code Find candidate US tariff codes for a product ~123
Search the official US Harmonized Tariff Schedule by plain-language product description and get back candidate HTS lines with their duty rates. Classification is the hard part of importing and the usual place a costly mistake is made, so this returns several candidates with their descriptions rather than pretending there is one obvious answer.
| Name | Type | Req | Description |
|---|---|---|---|
| description | string | yes | What the product is, in plain words. For example 'women's merino wool leggings' or 'brassieres'. |
| limit | integer | – | How many candidates to return, 1 to 40. Default 15. |
No output schema declared.
No examples provided.
lookup_us_duty_rate Look up the US duty rate that governs an HTS code ~171
Given a US HTS code, returns the duty rate that actually applies, resolving the common trap that rates sit on the 8-digit line while the 10-digit statistical lines underneath are blank and inherit. Optionally pass the country of origin to see whether a free-trade rate is available. Always reports what is excluded, because trade remedies such as Section 301 are not in this data and can dwarf the base rate.
| Name | Type | Req | Description |
|---|---|---|---|
| hts_code | string | yes | A US HTS code, with or without dots: 6212.10.90, 6212109010 or 6212. |
| origin_country | string | – | Optional ISO 3166-1 alpha-2 country of origin of the GOODS, for example CN or AU. Used to check free-trade eligibility. |
No output schema declared.
No examples provided.
