Holdmark is a registry of online stores that publish verified facts about delivery and refund behavior. Muse can look up whether a store delivers its orders (verified with carriers) and refunds money (verified with payment processors), helping you decide where to shop.

Example request: "Before I buy from this store, does it actually deliver orders and refund money?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use holdmark to help me. It is a free service with an MCP server at https://holdmark.org/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- find_stores: List the online stores in the holdmark registry, with a summary of their published facts. Each store publishes the same facts under the same rules: whether it delivers its orders (checked with the carrier) and whether it refunds money (checked with the payment processor). holdmar
- get_store: Read the full holdmark record for one store, by its domain. Figures are rounded against the merchant, order volume is published in bands rather than exact numbers, and every figure carries the period it covers and the source it came from. A fact with no data answers "not_measured
- how_holdmark_works: How every figure in the registry is calculated, what the words mean, and above all what holdmark does NOT measure. Read this before drawing a conclusion from any record: it is what stops a figure being read as something it is not.
