# Who am I

> Which key you're using, its scopes, and the CatchBack account it acts as.

Scope: none (any valid key) · MCP tool: `whoami`

Use it to check which CatchBack account your key is linked to. Quote `account.id` when you fund the account or contact us. An unlinked key gets `linked: false` here; the account endpoints return `403` for it.
