usitc
usitc_browse_chapter
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
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.
usitc_get_heading
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.
usitc_list_reference
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.
usitc_lookup_duty_rate
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.
usitc_search_hts
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.

How MCP servers expose tools in the first place →
Is Usitc Tariffs MCP Server working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 573 ms. The bar chart above shows every period we have measured.
How do I connect Usitc Tariffs MCP Server?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Usitc Tariffs MCP Server need an API key?
No. Usitc Tariffs MCP Server completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Usitc Tariffs MCP Server?
It answers our handshake in 573 ms on average, which is faster than 20% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Usitc Tariffs MCP Server?
The npm package @cyanheads/usitc-tariffs-mcp-server was installed 536 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Usitc Tariffs MCP Server open source?
The code is open source: it is published under the Apache-2.0 licence, written in TypeScript, 1 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at usitc-tariffs.caseyjhand.com, which runs on its operator's own terms.
