Frequently asked questions

What is a Personal Access Token (PAT)?

A PAT is a token created in the Authn8 dashboard that authenticates the MCP server to access your 2FA accounts.

How do I set the environment variable?

Set the `AUTHN8_API_KEY` environment variable to your PAT token before running the server, e.g., `AUTHN8_API_KEY=pat_xxx`.

Which MCP clients are supported?

Configurations are provided for Claude Desktop, Claude Code (CLI), and Cursor.

How do I get a specific OTP?

Use the `get_otp` tool with either `account_id` (UUID) or `account_name` (partial match). If multiple accounts match, the tool returns a list.

What does the `whoami` tool return?

It returns details about the current token, including the business name, token name, scoped groups, account count, and expiration date.
