KeyID gives Claude the ability to run complete signup flows by coordinating email, SMS, and TOTP artifacts with browser state. You start a registration session for a service, wait for verification codes or magic links to arrive, save cookies and localStorage when the account is provisioned, then mark the session complete. The hosted endpoint at keyid.ai/mcp manages an encrypted identity across chat sessions, or you can run the stdio package locally with your own Ed25519 keypair. Reach for this when you need an agent to create accounts, handle two-factor flows, or maintain browser continuity across multiple signup steps without manual copy-paste of verification codes.
