TWZRD Muse connector: check the listing before your agent buys.

Shopping agents are starting to buy things for people, but an agent cannot tell what a store actually promised. TWZRD publishes signed, expiring listing cards. Each claim (price, payment methods, returns, delivery) carries the page it came from and when it was observed. Anything nobody has verified is marked unknown instead of guessed.

The connector serves those cards over MCP at https://intel.twzrd.xyz/muse/mcp. It is a read-only pilot covering one listing (Vuori Kore Short, Ink, US) with six tools: get_shopping_check, check_listing, get_claim, get_evidence, get_publication (Ed25519-signed record) and verify_x402_settled_claim.

Demo: Meta's Muse agent (muse-spark-1.3) is told the checkout quote is 98 USD. It calls check_listing and get_shopping_check, sees the card advertises 78 USD, and answers "Do not pay now": check_failed, phantom_markup_detected.

check_listing has three outcomes, all shown live in the video:
- quote matches the card: advertised
- quote above the card: check_failed (phantom markup)
- store with no card: unknown_seller (unknown is not clean)

Every result carries authorizes_spend: false. The connector supplies evidence; a person or the agent's own policy decides the purchase. No tool places an order, opens a checkout, or moves money. All calls in the video are live and cost nothing.

Try it with any MCP client: POST https://intel.twzrd.xyz/muse/mcp (initialize, tools/list, tools/call check_listing). Discovery: https://intel.twzrd.xyz/.well-known/mcp.json
