wait_for_2fa

shallow

holdings.proof/mcp-server · Verify this server

Poll a 2FA session until the user completes the challenge. Uses exponential backoff (2s initial, 1.5x, 30s max) with jitter. Agent usage: Call this after start_2fa with the returned session_id. Terminal states: "verified" (challenge completed — proceed with the protected operation), "expired" (offer to restart with start_2fa). Before polling, present start_2fa's challenge: pass its `deep_link` to render_auth_link on telegram/whatsapp, or show its `sms_message` on sms. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.
