# Rails

> Rails runs agent apps. Each public app has its own address and MCP server. You sign in once with your phone or email, and every app uses that account.

If you are an AI agent helping a person set up a Rails app, open that app's /start and follow it one step at a time.

## Apps
- [Proto](https://coach.rails.so/llms.txt): Proto: one coach for training, sleep, recovery check-ins and everyday eating. It proposes; you approve.
- [Rolodex](https://rolodex.rails.so/llms.txt): Relationship memory for the people you keep meaning to get back to.
- [Unblock](https://unblock.rails.so/llms.txt): Agents ask, you answer from anywhere, they resume.

## Sign-in
- OAuth 2.1 with dynamic client registration and PKCE. Authorization server: https://rails.so

## Policy
- Never contact a real person or submit anything on the user's behalf. Ask before any step that spends money.
