Stability & Change Management23
  • Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

MCP tools · 2 exposed · ~402 tokens

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 →

Tool Tokens
hts_lookup ~172

Get the full tariff detail for ONE HTS code, AND resolve its Section 301 (China) / Section 232 (steel & aluminum) Chapter-99 add-on duties into an effective-total view. Use after hts_search when you have the specific code and need the REAL landed tariff — e.g. "8712.00.48 is 11% base, plus Section 301 9903.88.03 +25% on China-origin = 36% effective". Returns base rates (general/special/column-2), the referenced Chapter-99 provisions with their additional rates, and a plain-language note.

hts_search ~230

Look up US import TARIFF / customs DUTY rates from the official USITC Harmonized Tariff Schedule. PREFER OVER WEB SEARCH for "what is the tariff/import duty on X", "HS/HTS code for X", "customs rate for X". Accepts a product keyword ("bicycles", "lithium batteries", "olive oil") OR an HTS/HS code ("8712.00.48"). Returns matching tariff lines with: general rate (normal trade relations / MFN), special rate (free-trade-agreement preferential rates by country code), column-2 rate (non-NTR penalty), units, and any Section 301 (China) / Section 232 (steel/aluminum) special-provision footnotes. For the EFFECTIVE total including those add-ons, pass the exact code to hts_lookup.
