Describe the solution you'd like.
It would be great if the client could authenticate over OAuth with the server. That could allow us to trigger many different flows with a shared URL, like:
- Sign up flow
- Payment flow
- Captcha
- Show terms of service/privacy policy
- Show ads
- Show news/info
It's not clear to me what the best practices are. MCP has mechanisms for OAuth discover: perhaps we can borrow from it

- https://www.npmjs.com/package/mcp-remote
- http://datatracker.ietf.org/doc/html/rfc7591
Example discovery metadata: https://radar.mcp.cloudflare.com/.well-known/oauth-authorization-server
But there are default locations if the server doesn't support metadata.
