Sign in to Rivian with the RIVIAN_EMAIL and RIVIAN_PASSWORD set in the MCP server configuration. Call it when no session is saved or after the session expires; a saved session is restored on launch. Takes no arguments. Replaces the current session and saves it to ~/.rivian-mcp/session.json. When Rivian requires two-step verification, it sends a code to your phone or email and the sign-in stays pending until you pass the code to rivian_submit_otp. Returns a message saying either that you are signed in or that a code was sent, and an error if the credentials are missing or Rivian rejects them.

Finish a Rivian sign-in with the verification code Rivian sent to your phone or email. Use it only after rivian_login reported that a code was sent; without a pending sign-in it returns an error and asks you to call rivian_login. On success it saves the session to ~/.rivian-mcp/session.json. Uses the RIVIAN_EMAIL set in the MCP server configuration. Returns a message saying you are signed in, or an error if Rivian rejects the code.
