Tell Grok Bot to add PackIndex — it confirms, you authorize, and every packaging question gets a benchmark with its date. In the Grok app, add it once under Connectors.
Grok Bot signs in through your Cursor account, so the sign-in page names Cursor. A server added in Cursor's settings does not carry over to Grok Bot. Uses your PackIndex plan.
Illustration of PackIndex in Grok; the real screens may differ slightly. The PP value is real PackIndex data (free view as of 2026-08-03 · live on Essential).
“What does PET resin cost today?” Value in USD and your currency, with 1-week, 1-month and 1-year change.
Open →“My supplier quotes $1,450/t for PP. Is that fair?” Verdict against the benchmark and its 12-month range.
Open →“Our contract was €1,300/t in March, 60% linked to PP. What should we pay now?”
Open →“Compare kraftliner in Europe and the US” and 12-week outlooks with a confidence grade.
Open →“Design a mailer box for 2 mugs and cost it.” Spec and priced bill of materials — 1 Suite run.
Open →“Who can make my folding carton in Canada?” Live Exchange listings and matched converters.
Open →Only after you confirm. Up to 3 suppliers per request, within your Exchange plan.
Open →In chat say: “Add a custom MCP server called packindex at https://opnplatform.com/api/mcp”. Select Add it, then Authorize and sign in. Type @ and pick packindex to use it.
Open grok.com/connectors → New Connector → Custom and paste the server address. Price questions work without signing in. On Grok Business an admin adds the connector for the team first.
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 · Claude · Microsoft Copilot · Cursor, and any MCP client — tools, permissions and setup.
