Rendobar MCP tools 9
get_accountGet the authenticated account's credit balance, plan, and limits. Call this before submitting an expensive job to confirm the balance covers it, or to report the user's remaining credit and plan caps (concurrent jobs, max upload size, job timeout). Takes no arguments. Read-only and idempotent — it never spends credit or changes anything. Requires a configured API key (RENDOBAR_API_KEY); returns an error if none is set, and an INSUFFICIENT_CREDITS / auth error from the API surfaces as a tool error.
