Connects Claude to Russia's Честный ЗНАК (Chestniy ZNAK) product marking verification system. Three public tools work without auth: check_marking_code validates authenticity, get_product_info pulls manufacturer and brand details, and check_batch handles up to 50 codes at once. Add a CHESTNYZNAK_TOKEN to unlock search_products and get_cis_info for deeper queries against the authorized API. Useful if you're building compliance tools, retail verification workflows, or consumer protection features that need to validate Russian product marking codes. Part of a 50-server Russian API series. Public endpoint hits mobile.api.crpt.ru, authenticated calls go to markirovka.crpt.ru.
