Claude connects through a browser sign-in, so there is no config file to edit. You give Claude a URL; it opens a Notifylyst page where you paste the token once. Works the same in Claude web, desktop and mobile.
1

Add the custom connector

In Claude: Settings → Connectors → Add custom connector, then paste your connector URL.
Copy the real URL from the app. The Connector URL field on Settings → Developers → AI connectors (MCP) has it with your store filled in. The URL must end in /mcp. The ?shop= part only tells two stores’ connectors apart — the store always comes from the token you paste next.

Paste your token

Press Connect. A browser page titled Connect to Notifylyst opens. It says Claude wants to connect and asks for a token to choose which store and which tools it gets.Paste the nl_mcp_… token from Create an access token into MCP access token and press Continue. This is the only time you handle it.
The help text on this page still says “Settings → MCP Integration”. That is the same place as Settings → Developers → AI connectors (MCP).
If the token can’t be used, the page tells you why — expired, disabled, the connector switched off for the store, or not recognised. See Error codes.

Authorize access

The next page, Authorize access, shows:
  • the store the token belongs to — check it is the right one;
  • the token’s name and its expiry, or “no expiry”;
  • Read access and Write access, listing the tools the token allows. A read-only token shows “None — this is a read-only token.” under write access.
Authorizing grants exactly what the token already allows — it never widens it. Press Authorize (or Deny to stop).

Back in Claude

Authorize sends you straight back to Claude, which shows the Notifylyst connector as connected, with the tools your token allows.

Authorizing doesn’t check your plan. On a plan without AI MCP Integration you can connect, but every call is refused with MCP_PLAN_DISABLED.

Verify it works

Start a new chat and ask for something that needs one read tool:
You should get store details, plan, active channels and wallet balance. Then try a real question:

​
Reconnecting later

Claude uses your token directly, and there is no separate renewal. When a token expires, or you revoke or regenerate it, the connector stops working: create a new token (or use the regenerated one) and connect again the same way. If Claude reports an error instead of an answer, Troubleshooting maps each one to its cause.
