Client Credentials

Call configure + fetch tool; token auto-refreshes.

Device Code

1. Start tool → returns user_code & verification_uri.
2. Poll tool until token stored.

Auth Code (PKCE)

1. Generate authorize URL (tool output includes state & code verifier).
2. User completes consent → obtain code.
3. Exchange code via tool → stores access & refresh tokens.

Refresh

Automatic if refresh_token present else client credential logic.

Troubleshooting: | Issue | Action | | —– | —— | | No token after poll | Interval too short; respect slow_down | | 401 after refresh | Refresh silently failed → reconfigure |
