    Lists tools

    tools/list returned 3 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 82 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 82 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

    Every tool description is at least 20 characters.

  • Pass

    Website matches publisher

    The website host does not match the reverse-domain namespace.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

Capabilities

estimate_us_duty

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.

Discovered
find_hts_code

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.

Discovered
lookup_us_duty_rate

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.
