Changes things 1Claude Code: ask
  • tariff_lookupAs-of customs-tariff lookup: which measures/duty rates apply to a goods code in a jurisdiction (eu, us, uk, jp), optionally from an origin, on a date.No findings

    Why it is in this group

    • The name "tariff_lookup" says "lookup": a word for reading.
    • The input takes a statement or command to run (input.code), which can change anything it can reach.
    Description, as the server wrote it
    As-of customs-tariff lookup: which measures/duty rates apply to a goods code in a jurisdiction (eu, us, uk, jp), optionally from an origin, on a date. Duty expressions are verbatim; every measure carries its legal citation. Not legal advice.
Only reads 5Claude Code: allow
  • get_seriesFetch ONE series with every dimension named by you (no guessing or relaxing): dataset, ISO3 countries, an ISO period range and a member code for every dimension from get_structure.No findings

    Why it is in this group

    • The name "get_series" says "get": a word for reading.
    Description, as the server wrote it
    Fetch ONE series with every dimension named by you (no guessing or relaxing): dataset, ISO3 countries, an ISO period range and a member code for every dimension from get_structure. Returns status ok/empty/refused with each value's provenance, and the missing country-periods listed. A bad request is a named 400 error saying which field and what is allowed.
  • get_structureThe published structure of one dataset, free: its dimensions with every member code and label, frequencies, period coverage, the ISO3 countries it serves, and whether it is servabl…No findings

    Why it is in this group

    • The name "get_structure" says "get": a word for reading.
    Description, as the server wrote it
    The published structure of one dataset, free: its dimensions with every member code and label, frequencies, period coverage, the ISO3 countries it serves, and whether it is servable. Call this before get_series to learn the codes to send. Dataset ids come from search_datasets.
  • get_tableFetch a STORED table whole, by dataset id (families cn-nbs-census and cn-nbs-yearbook): labelled rows × columns with original-language labels, English overlay, units, and provenanc…No findings

    Why it is in this group

    • The name "get_table" says "get": a word for reading.
    Description, as the server wrote it
    Fetch a STORED table whole, by dataset id (families cn-nbs-census and cn-nbs-yearbook): labelled rows × columns with original-language labels, English overlay, units, and provenance down to the source file. Ids look like 'cn-nbs-census:2010_a0101a'.
  • resolve_dataAsk a data question in English ('unemployment rate in Japan', 'compare GDP in Japan and Germany') — resolves to the best covering dataset and returns the observations, with coverag…No findings

    Why it is in this group

    • The name "resolve_data" says "resolve": a word for reading.
    Description, as the server wrote it
    Ask a data question in English ('unemployment rate in Japan', 'compare GDP in Japan and Germany') — resolves to the best covering dataset and returns the observations, with coverage honesty (missing countries are reported, never papered over).
  • search_datasetsSearch StackData's catalog of 50k+ official statistical datasets (SDMX/World Bank dataflows, China censuses and yearbooks, tariff schedules).No findings

    Why it is in this group

    • The name "search_datasets" says "search": a word for reading.
    Description, as the server wrote it
    Search StackData's catalog of 50k+ official statistical datasets (SDMX/World Bank dataflows, China censuses and yearbooks, tariff schedules). Multilingual: an English query finds Chinese-titled tables. Returns dataset ids usable with the other tools.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
