    Server tool list (9)

    Raw names from tools/list. Only developers need these.

    tariff_lookupLookup a Swiss customs tariff (HS8) and return the full TARES row including MFN duty, preferential regimes, restrictions and customs relief codes. Always returns a non-official disclaimer that the agent must surface to the end user.
    kyc_checkSearch the FINMA registry of supervised entities and the FINMA warnings list by name. Returns up to top_k authorised entities + any matching warning entries. Use this for basic counterparty KYC screening.
    cross_walkTranslate an industry classification code between schemes (NOGA 2008/2025, NACE 2.0/2.1, ISIC 4). Returns all mappings with their type (exact, partial, aggregated, derived) and notes.
    tariff_semantic_searchSemantic search across Swiss customs tariff (TARES) descriptions in French. Uses pre-computed Xenova/paraphrase-multilingual-mpnet-base-v2 embeddings (768d, FR) shipped with the TARES Pro bundle. Returns top-K HS8 codes by cosine similarity. Always inlines a non-official disclaimer.
    classify_textClassify a free-text business description into top-K NOGA 2025 codes with confidence scores. Uses pre-computed Xenova/paraphrase-multilingual-mpnet-base-v2 embeddings (768d, FR). NACE 2.1 mode falls back to NOGA 2025 in v1 — combine with cross_walk for translation.
    finma_searchFuzzy search the FINMA registry by name (tolerates typos and legal-suffix variants like 'UBS Switzerland AG' vs 'UBS AG'). Returns top-K matches with confidence score, including LEI/UID where available. Set include_warnings=true to also surface entries from the FINMA warnings list.
    tariff_changelogReturns the historical changelog of MFN duty rates (and adjacent fields) for a Swiss customs tariff (HS8) code, across every dated release we have archived (history deepens over time from launch). Irreplicable by scraping — xtares.admin.ch only serves the current version. Requires `hs8`; optional `since` (ISO date) to bound the window.
    entity_historyReturns the timeline of changes for a FINMA-supervised entity (registration, authorisation type changes, status mutations, address moves, warning-list flag transitions). Keyed by Swiss UID (CHE-xxx.xxx.xxx). Irreplicable by scraping — finma.ch only publishes the current state.
    statent_lookupSwiss enterprise statistics (STATENT, BFS) for a NOGA 2-digit division and optional canton. Returns count of establishments, jobs, and full-time equivalents (FTE). 2023 data. Always inlines a BFS attribution disclaimer.
