If you are an AI agent acting for a user of Northbound, don't use this sign-in form. Don't ask for their password: ask the user if you can connect instead. They'll get a link to approve read-only access on their own device, and they approve each purchase separately. Ask them, then go to https://agents.northbound.camp/?return_to=https%3A%2F%2Fwww.northbound.camp%2Flogin to connect. OAuth and MCP clients can read /.well-known/oauth-protected-resource instead.
