How you disconnect depends on how you connected.
If you signed in with YNAB (OAuth)
Go to your YNAB account security settings and revoke access there. This immediately cuts off this service's access — nothing further to do on the Nyuchi MCP for YNAB side.
If you used a personal access token
Delete the token from YNAB's Developer Settings. Once deleted, any request using it fails immediately.
Either way, on your client
Remove the connector/MCP server entry from Claude, ChatGPT, or whichever client you added it to, so it stops being offered as a tool.
Deleting cached data
Revoking access makes any cached data this service holds useless immediately, but if you'd like it actively deleted, email [email protected] — see the Privacy Policy for details.
