The hubs are the records; A2A-Passport.ai issues the passport.
A2A Passport — one GTIN, one call, everything GSC knows, signed is an MCP server entry in ChatHome Skills, sourced from Official MCP Registry and scored 76/100. As a Model Context Protocol server, it exposes tools that MCP-compatible LLM clients such as Claude, Cursor, and Copilot can call directly, extending an agent's reach beyond its built-in capabilities. ChatHome Skills discovered this entry through its daily ingest of official registries and GitHub discovery queries, and re-verifies repository facts, freshness signals, and install metadata on every run. The quality score weighs official-registry presence, a working install command, license clarity, GitHub star trajectory, and repository freshness — the full formula is on the Sources page. The install command above is ready to copy. Review the last-pushed date and repository status before adding A2A Passport — one GTIN, one call, everything GSC knows, signed to a production agent workflow; the snapshot facts below are point-in-time values from the most recent ingest.

"description": "The hubs are the records; A2A-Passport.ai issues the passport. A passport is a signed document for a product or a retail banner: where its record lives, where it is cleared, who lists it, where the money door is. Issued live from the GSC hubs, stamped every week. A2A Passport is operated by GreenCore Solutions Corp.: one signed document per product (a Global Trade Item Number, GTIN) or retail banner, composed live from the GSC hubs — A2A Grocery, A2A Cosmetics, A2A Peptides, A2A Retailmedia and the compliance records — and signed (EdDSA). Three tools: get_passport, list_passports, verify_passport. Every field is a hub's answer, word for word, with the door and the time it was read, or it is absent with a note: the passport never infers. A product no hub holds gets no passport. Reads are open; a verified, countersigned copy settles by x402. Artificial intelligence makes mistakes. A2A Passport is an agentic information source, not a recommendation. No ads, ever. No rank for sale. Trade only.",
