No. Price questions work without an account and show the free reference values. Signed in, your own PackIndex plan applies exactly as on the website: live values on Essential and above, Suite runs for Design Studio, PACKIQ credits for agents and your Exchange plan for RFQs.
Only what the assistant passes to a PackIndex tool, such as an index code or a quantity — never your chat history, memories or files.
Remove PackIndex in the assistant, or open opnplatform.com/portal → Settings → MCP Access and revoke it.
PackIndex also works in ChatGPT · Microsoft Copilot · Cursor · Grok, and any MCP client — tools, permissions and setup.
