A2A Passport — one GTIN, one call, everything GSC knows, signed
The hubs are the records; A2A-Passport.ai issues the passport.

Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (3)
🟢get_passport(subject, kind)
The signed passport of a product (a Global Trade Item Number, GTIN) or a retail banner (market/banner, e.g. FR/Carrefour): which hub holds its record, where it is cleared, its compliance records, who lists it, where the payment door is. Read live from the GSC hubs on every call; the first call issues version 1. subject = a GTIN (8 to 14 digits) or market/banner; kind = gtin or banner (optional).
