You only need this if you're using the "your own token" connection option instead of "Sign in with YNAB" — see Connecting to Claude, ChatGPT, or another MCP client.
Go to app.ynab.com/settings/developer (log in to YNAB first if you aren't already).
Under Personal Access Tokens, click New Token.
Enter your YNAB password to confirm, and copy the token shown — YNAB only shows it once.
Use it as
https://ynab.nyuchi.com/mcp?token=<your-token>, or send it as anAuthorization: Bearer <your-token>header if your client supports custom headers.
Revoking a token
Delete it from the same Developer Settings page at any time — this immediately cuts off this service's access to your budget, with nothing to do on the Nyuchi MCP for YNAB side.
