Connect OPEN to your chat assistant
OPEN answers one question: is this business open right now, and until when. This connector brings that answer into Claude, ChatGPT or Grok, with an interactive map inside the conversation. The data comes from business owners in real time, not from guessed opening hours.

The tools
Four tools, all read-only. No writes, no sign-in, and no access to anyone's personal data.
- open_now
- What is open right now around a point, and until when. Takes explicit coordinates, a place name as free text, or nothing at all - in which case it centres on downtown Jerusalem and the answer says explicitly that this is a default. Renders a map.
- search_businesses
- Search a business by name or description, with a live status on every result. Renders a map.
- get_business
- One business in full: status now, how long it stays open, the coming week of effective hours including special dates, and how fresh the information is.
- list_categories
- The category list, to use as a filter in the other tools.

Where there is coverage
OPEN is in pilot in Jerusalem. The catalogue is small and grows through in-person recruitment, so a query about another city returns very little or nothing. That is the state of the product, not a fault.
A business with no fresh information reads UNKNOWN. UNKNOWN is never CLOSED, and the connector instructs the model explicitly not to present it that way.
What data moves through this
The connector reads public business information only: name, category, address, coordinates, hours and status. It has no access to user profiles, favourites, reports or any other table, and that boundary is enforced in the database itself.
If you ask what is open near you, the coordinates are sent to the server to sort results by distance. They are not stored and no location history is kept. The "my location" button inside the map runs only after you explicitly press it.
Business names and descriptions are treated as data, not instructions, and are sanitised before they reach the model.
What the connector does not do
It performs no writes of any kind: you cannot update a status, file a report, change hours or touch a business through the chat. Status updates happen only by the business owner, in the app or in the owner area of the website.
It carries no advertising, no payments and no sponsored content.
