Q: How does Claude Desktop handle biometric passkeys during testing with Corbado?

The desktop client initiates the flow by calling startpasskeylogin to get the challenge parameters. It cannot trigger your physical device's fingerprint scanner directly, but it verifies the backend handshake using finishpasskeylogin with mock or pre-signed assertions.

Run WebAuthn setups inside Claude Desktop

The Corbado MCP Server exposes tools to handle biometric authentication flows directly from your chat interface. You run `init_signup` to kick off a registration sequence, followed by `start_passkey_append` to prepare the credential payload. Your agent triggers these endpoints to verify how your backend handles WebAuthn payloads. It uses `finish_passkey_append` and `verify_signed_data` to confirm the signature verification works without you writing manual test scripts.

Query and modify user directories with Claude

This integration provides direct tools for user administration operations inside your workspace. You query existing records using `get_user` or `list_users` to verify profile states during debugging sessions. When testing edge cases, your agent executes `create_user` or `delete_user` on the fly. This saves you from constantly switching to the browser dashboard just to wipe a test account or update an email address.

Inspect live authentication processes and sessions

This MCP Server exposes session-state tools to let your agent inspect active login states. You track active sessions with `list_sessions` and terminate compromised or stale credentials using `revoke_session`. If an authentication state gets stuck during testing, your agent runs `reset_auth_process` to clear the state machine. This lets you restart the signup or login flow instantly within the Claude Desktop environment.
