RCO answers one question for an AI agent about to order: can this product be sold in this market? The answer is a signed record, resolved before the agent asks, verifiable against a published key. Agents consume the result of the rules, not the rules themselves.
Every GSC hub gate calls it before an order — A2A Grocery, A2A Cosmetics, A2A Peptides, A2A Retailmedia. Green proceeds. Yellow proceeds with the condition in the order. Red refuses with the record. None refuses: nothing is ordered without the light.
https://mcp.rco-a2a.ai/mcp — no account, no authentication on reads, typed answers, signed records. Markets of record: AE, AU, BE, BR, CA, CH, DE, ES, EU, FR, UK, IN, IT, JP, KR, MX, NL, PL, SG, TH, US, VN.
RCO is one door with one card. It mints no agents. Records verify from the keyring (kid gsc-rco-2026-08); issuers from the signed registry at consortium-10060.org. Every record carries an independent Azure Confidential Ledger receipt.
