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 Security83
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability59
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1345 tokens (~224/item across 6 items; 6 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 Management33
- Stability observed for 10 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
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

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 →
usitc_browse_chapter Browse published HTS chapter headings ~166
Browse numbered headings with complete distinct eight-digit rate-line relationships and independent ten-digit statistical counts. A unique combined ten-digit source row can establish an absent eight-digit relationship. Published subchapter titles group following headings when present. Chapters 98 and 99 expose actual published entries without synthetic four-digit headings; grouping is unavailable without sourced markers. Reserved chapters can return a successful empty collection.

usitc_check_additional_duties Research Chapter 99 additional-duty evidence ~287
Find Chapter 99 candidate headings and source references for an exact eight- or ten-digit commodity number. Coverage is partial and empty candidates never establish clearance. Use candidates, evidence with a returned candidateCode, or unmapped views; follow returned noteId and noteCursor for complete source passages. Country comparisons retain unknown and different-country evidence. No applicability, current legal status, exclusions, stacking or combined duties are determined.
| Name | Type | Req | Description |
|---|---|---|---|
| candidateCode | string | – | Returned Chapter 99 candidate number, only with view evidence. |

| cursor | string | – | Opaque nextCursor from the same tool with identical arguments. |
| limit | integer | – | Requested items as a positive safe integer; effectiveLimit discloses clamping to at most 100, and pages may be byte limited. Keep the same requested limit for continuation. |

usitc_get_heading Inspect an HTS heading and ancestry ~195
Inspect a four-, six- or eight-digit HTS classification and its complete indented descendants, including unnamed superior rows. Published section titles are retained separately in sections, outside legal ancestry. Ancestry is built from the whole containing heading before filtering. Each parent and inherited-rate source has an exact nodeId follow-up. Chapters 98 and 99 preserve published forest roots without inventing four-digit records.
| Name | Type | Req | Description |
|---|---|---|---|
| code | string | yes | Four-, six- or eight-digit HTS code, bare or conventionally dotted. |
| cursor | string | – | Opaque nextCursor from the same tool with identical arguments. |

No examples provided.
usitc_list_reference Decode HTS references and published editions ~144
List accepted identifier formats, edition-pinned Special Program Indicators, chapter/section navigation labels, quantity units or published release metadata. Program names are decoded separately from country membership, which remains unknown without independently verified lists. Release records identify published editions but do not enable historical tariff lookup. Follow nextCursor for all entries.
| Name | Type | Req | Description |
|---|---|---|---|
| cursor | string | – | Opaque nextCursor from the same tool with identical arguments. |
| limit | integer | – | Requested items as a positive safe integer; effectiveLimit discloses clamping to at most 100, and pages may be byte limited. Keep the same requested limit for continuation. |

No examples provided.
usitc_lookup_duty_rate Look up published base duty columns ~177
Retrieve an eight-digit rate line or exact ten-digit statistical number with all published General, Special and Column 2 cells. An explicit eight-digit row takes precedence; an absent one resolves only through a unique ten-digit source row, retaining its identity. Multiple suffixes stay unresolved. Blank statistical cells inherit only from the matching eight-digit legal ancestor. With countryCode, report edition-matched General Note 3(b) listing; Special-program membership stays unknown. Neither comparison establishes qualification or selects a column. Follow usitc_check_additional_duties for partial Chapter 99 research.
| Name | Type | Req | Description |
|---|---|---|---|
| code | string | yes | Exact eight- or ten-digit HTS identifier, bare or conventionally dotted. |
| countryCode | string | – | Assigned ISO 3166-1 alpha-2 country; comparison only, never sent upstream. |

| row | object | – | Original published source row, including a unique combined row when resolving an absent eight-digit number. |
| source | object | – | Source provenance. |
| specialPrograms | object | – | Decoded nonblank Special cell, preserving unmatched text. |
| totalCount | integer | – | Complete locally filtered item count. |
No examples provided.
usitc_search_hts Search published HTS classifications ~152
Search published USITC descriptions or complete HTS code prefixes in source order. Matches are flat published rows with unresolved rates; call usitc_get_heading for legal ancestry and usitc_lookup_duty_rate for exact base rate columns. Follow nextCursor with identical arguments for all remaining matches.
| Name | Type | Req | Description |
|---|---|---|---|
| cursor | string | – | Opaque nextCursor from the same tool with identical arguments. |
| limit | integer | – | Requested items as a positive safe integer; effectiveLimit discloses clamping to at most 100, and pages may be byte limited. Keep the same requested limit for continuation. |
