New to Muse?Muse is Meta's AI assistant. Mercantry Registry is an app you add to it, and once it is on, you can ask Muse to do this for you: search and book restaurants in la, hong kong and tokyo with honest merchant data and real feedback. It takes about two minutes and you can turn it off any time.

Is it safe to connect?

What Muse can see: It does not ask you to sign in, so it cannot see your accounts. It only sees what Muse sends it from your request.

Before it acts: Read what Muse plans to do before you approve it, and remove the app from Muse when you stop using it.

How to add it to Muse

Not in Muse's Connectors list yet, but Muse can still use it. Copy the request below and paste it into Muse. 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.

Also use it in ChatGPT or Claude

Mercantry Registry is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.

Add it to ChatGPT
  1. 1

    Open ChatGPT settings

    In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).

  2. 2

    Turn on developer mode

    Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.

  3. 3

    Create the connector

    Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.

  4. 4

    Use it in a chat

    Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.

Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT

Add it to Claude
  1. 1

    Open Claude settings

    In Claude, open Settings, then Connectors.

  2. 2

    Add a custom connector

    Choose Add custom connector, give it a name, and paste the link.

  3. 3

    Connect and use it

    If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.

Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

Tools · 9

search_merchantsFilter-based search over the restaurant registry (coverage cities + timezones in get_registry_meta). NOT ranked: results come back in deterministic order (merchant_id ASC by default; distance ASC when lat/lng given and order_by="distance"). Returns compact records with pagination
get_merchantEvery field the registry holds on one merchant: schema fields, structured hours, raw feedback history, platform-observed operational stats, and per-field provenance with timestamps. Maximal data, zero opinion — the registry never scores or ranks.
get_availabilityV1 does NOT hold live table availability — availability is checked on the phone call at booking time. This tool returns the merchant's reservation policy, structured hours, and holiday exceptions so you can pick a plausible time before calling place_booking.
place_bookingRequest a table reservation. Returns booking_id with state 'queued' immediately; fulfillment is asynchronous (a call is placed to the merchant). Poll get_booking_status or supply callback_url for webhooks. RETRY SAFETY: pass a unique client_reference_id (recommended: always); if
get_booking_statusState machine position for a booking: pending → queued → in_progress → confirmed | failed | needs_input (plus cancelled). Includes structured details on confirmation (confirmed_time, confirmation_code, merchant_instructions), structured failure reason (no_answer | fully_booked |
modify_bookingAmend a booking before or after the call. For a booking in needs_input: pass accept_option_index to take one of the merchant's offered times (confirms immediately), or pass a new datetime/party_size to re-queue an amended request. Modifying an already-confirmed booking cancels it
cancel_bookingCancel a booking in any non-terminal state, or a confirmed reservation (the registry notifies the merchant). Cancellation is mandatory when the human no longer wants the table — no-shows destroy merchant trust and are tracked per developer key.
submit_feedbackReport how a confirmed reservation actually went. Accepted only against a confirmed booking_id, once per booking, within 14 days of confirmation. Structured fields first; optional free text ≤ 500 chars. This corpus is served raw to all agents via get_merchant — it is never editor
get_registry_metaEvaluate the registry itself: per-city coverage (with each city's IANA timezone), merchant/bookable counts, verification and freshness stats, feedback corpus size, schema version, and the documented deterministic ordering rule. Honest by design — including how stale the data is.
