MCP server for Chestnyi Znak (Честный Знак) — Russia's national product labelling system (True API).
Enables AI assistants (Claude, Cursor, etc.) to query marking codes, documents, warehouse balances, and participant data directly via natural language.

This server requires a JWT token from your Chestnyi Znak personal account. Token acquisition involves GOST cryptography (КриптоПро + УКЭП) and is outside the scope of this package.
Token retrieval can be automated — using a local КриптоПро script, a signing microservice, USB-over-IP with a hardware token, or a cloud HSM. It can also be done manually via the Chestnyi Znak web interface. The right approach depends on your infrastructure, OS, certificate type, and security requirements. Because the options and constraints vary significantly from case to case, this is treated as a separate integration task. We handle this kind of setup as well — feel free to reach out.
Token lifetime: ~8–12 hours. Update the file when it expires — the server picks it up automatically without restart.
Add to your claude_desktop_config.json:
Sandbox:
{
"mcpServers": {
"chestnyi-znak": {
"command": "npx",
"args": ["-y", "@woyax/mcp-chestnyi-znak"],
"env": {
"CHZ_TOKEN_FILE": "/path/to/your/token",
"CHZ_ENV": "sandbox"
}
}
}
}
Production:
{
"mcpServers": {
"chestnyi-znak": {
"command": "npx",
"args": ["-y", "@woyax/mcp-chestnyi-znak"],
"env": {
"CHZ_TOKEN_FILE": "/path/to/your/token"
}
}
}
}
CHZ_ENV defaults to "prod" if not set.
Important: the token file and the
CHZ_ENVvalue must match — a sandbox token won't work on the production endpoint and vice versa.
| Variable | Required | Default | Description |
|---|---|---|---|
CHZ_TOKEN_FILE | Yes | — | Absolute path to file containing the JWT token |
CHZ_ENV | No | prod | Contour: sandbox or prod |
