  notes: >-
    The DualEntry Public REST API authenticates with a static API key in the
    X-API-KEY header. The hosted MCP server and the first-party CLI authenticate
    with OAuth 2.1 browser sign-in instead (no API keys), where permissions match
    the signed-in user's DualEntry role.

  issuance: >-
    Issued by an organization administrator in the DualEntry dashboard. The key
    is shown once at creation and cannot be retrieved afterward; store it in a
    secret manager or environment variable. Separate keys are recommended for
    development vs production.

  description: >-
    Browser-based OAuth 2.1 sign-in. The CLI stores credentials in the system
    keychain; the MCP server (https://api.dualentry.com/mcp/) signs in per
    client. Permissions are scoped to the authenticated user's DualEntry role.
    No public scope reference is documented.
