Changes things 2Claude Code: ask
  • sampuli_generateGenerate format-true, entirely synthetic test data for a country.No findings

    Why it is in this group

    • The name "sampuli_generate" says "generate": a word for a change.
    Description, as the server wrote it
    Generate format-true, entirely synthetic test data for a country. spec is "<country>.<selector>" where selector is a field key ("phone"), "person" (a full coherent record), or "preset:<key>" (a scenario). Values match each country's real formats and pass validators (IBAN mod-97, card Luhn, …) but are never real or registered.
  • sampuli_schemaGenerate rows from a custom schema, mixing generic types and country-accurate fields.No findings

    Why it is in this group

    • The description's first verb is "generate": a word for a change.
    Description, as the server wrote it
    Generate rows from a custom schema, mixing generic types and country-accurate fields. Each field has a name and a type — a generic type ("uuid", "int:0,500", "enum:free,pro,team", "date:2021,2025") or a country field spec ("ke.phone", "de.iban"). Optional per-field "blank" (0–1) makes it null that often.
Only reads 4Claude Code: allow
  • sampuli_describe_countryList a country's available fields (phone, national ID, tax number, IBAN, SWIFT/BIC, card, …) and preset scenarios.No findings

    Why it is in this group

    • The name "sampuli_describe_country" says "describe": a word for reading.
    Description, as the server wrote it
    List a country's available fields (phone, national ID, tax number, IBAN, SWIFT/BIC, card, …) and preset scenarios.
  • sampuli_fetchFetch synthetic test data from a natural request when you don't know the exact spec — e.g.No findings

    Why it is in this group

    • The name "sampuli_fetch" says "fetch": a word for reading.
    Description, as the server wrote it
    Fetch synthetic test data from a natural request when you don't know the exact spec — e.g. "a SWIFT code for China", "Kenya phone number", "German passport", "a Nigerian BVN". Sampuli resolves the country and field for you (China→cn, "SWIFT code"→swift) and generates a format-true value. Prefer sampuli_generate when you already have a spec like "cn.swift".
  • sampuli_list_countriesList every country Sampuli can generate synthetic test data for (90 countries), with the ISO code used as a spec prefix.No findings

    Why it is in this group

    • The name "sampuli_list_countries" says "list": a word for reading.
    Description, as the server wrote it
    List every country Sampuli can generate synthetic test data for (90 countries), with the ISO code used as a spec prefix.
  • sampuli_list_typesList the country-agnostic generic types (uuid, enum, int, float, date, vin, isbn, imei, mac, email, …) usable in a custom schema or as "any.<type>".No findings

    Why it is in this group

    • The name "sampuli_list_types" says "list": a word for reading.
    Description, as the server wrote it
    List the country-agnostic generic types (uuid, enum, int, float, date, vin, isbn, imei, mac, email, …) usable in a custom schema or as "any.<type>".

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.
