• approve_access_request ~168 tokens
  Approve a pending access request: issue a `member` invitation to the requester and resolve the request (level `admin` or `owner` of the request's tenant).

• complete_billing ~454 tokens
  Complete the tenant's billing details: legal-entity name and type, VAT id, invoice address, invoice email and optional PO reference. Call this when the owner or a billing contact has the details.

• list_consents ~152 tokens

• list_invitations ~118 tokens
  List all invitations for the caller's tenant, most recent first. Call this to show a tenant admin which invitations are pending, accepted, or revoked; the raw token is never included.
• list_members ~83 tokens
