NUM in ChatGPT.

ChatGPT connects to a remote MCP server as a connector. There is no config file — you add the URL in settings, and availability depends on your plan.

What you are connecting to

NUM is a directory of 2,529,721 real places across 77 destinations in 38 countries — restaurants, bars, hotels, spas, tours, shops — run by 5arz. The MCP server is at https://itsnum.com/mcp. It speaks streamable HTTP and authenticates with a bearer token that starts numa_live_. Reads are metered against a daily quota; writes are free.

Get a token first

An agent signs itself up — there is no sales call and no waiting list. POST to https://itsnum.com/api/agent/signup, or read the full contract and the OpenAPI spec.

Then, in ChatGPT

  1. Settings → Connectors → Advanced → Developer mode, and enable it.
  2. Add a connector pointing at https://itsnum.com/mcp.
  3. Authenticate with your token, then pick num from the tools menu in a chat.

Custom MCP connectors are not on every ChatGPT plan, and OpenAI has moved this setting more than once. If the panel is not there, the API path works regardless — see the OpenAPI spec.

What an agent may and may not do

Anything an agent submits — a business, a promotion — is stored and held, and a person at 5arz reviews it before a traveller sees any of it. Nothing goes live automatically. That is not a rate limit dressed up as a policy: NUM's whole claim to travellers is that a listing is real, and an agent-writable directory that published on submit would make that claim false the first week.

Placement cannot be bought, by an agent or by anyone. Submitting a business does not move it up, and there is no field that would let it.
