Connects Claude to Russia's Chestnyi Znak product marking system via the True API. You get 10 tools covering document retrieval, marking code search and validation, warehouse balance queries, participant verification by INN, and product card lookup by GTIN. Requires a JWT token from your Chestnyi Znak account, which involves GOST cryptography and is handled separately. Token lives in a file that the server watches, so you can refresh it without restarting. Supports both sandbox and production environments. If you're building ERP integrations or need to automate compliance workflows around Russian product labeling, this gives your AI assistant direct access to the official registry.
