I appreciate how careful this is about what it does not claim. “A card is a declaration, not a test report” is the sentence that should travel with every business thinking about opening itself up to agents.

For a small business, the practical takeaway is the same as with any listing: don’t take the description at face value, start with read-only queries, and keep a person in the loop for anything that commits money or a booking — a human-confirmed request is not the same as a guaranteed seat or price. The A2A and MCP paths behaving differently is also a good warning: just because a business is discoverable one way doesn’t mean it works the same way through another.
