PackIndex for AI assistants

Connect in two minutes

Server address: https://opnplatform.com/api/mcp · sign-in: OAuth (your OPN account) · transport: Streamable HTTP.

Claude (web, desktop, mobile): Settings → Connectors → search PackIndex in the directory, or Add custom connector and paste the server address. Select Connect, sign in to OPN and approve the permissions. Claude Code: claude mcp add --transport http packindex https://opnplatform.com/api/mcp.

ChatGPT: open Apps, search PackIndex and connect, then sign in to OPN. Before the listing is live, workspaces with developer mode can add the server address as a custom connector.

Microsoft Copilot (Microsoft 365 work accounts): in Copilot Studio create an agent → Tools → Add a tool → Model Context Protocol → server address, authentication OAuth 2.0 → Dynamic discovery. Publish to the Teams and Microsoft 365 Copilot channel; the agent then appears under Agents in Copilot chat. Consumer Copilot (personal Microsoft accounts) does not support custom connectors.

Other MCP clients (Cursor, VS Code, agents): add the server address; clients that support MCP OAuth open the OPN sign-in automatically. Scripts can send an opn_ API key as a Bearer token instead.

Sign-in and permissions

The first time a tool needs your account, the assistant opens an OPN sign-in page. You choose which permissions it gets; Read PackIndex data is always included and the others can be unticked. Every connection is per user, so each person's own plan, runs and credits apply.

Tools

This list is generated from the live server, so it always matches what your assistant sees.

Plans, costs and limits

Same rules as the web app. A connected assistant can never do more than you could in the portal, and it spends exactly what the same action costs there. Your balance is shown in tool results.

• Without an account or on the free plan, index values are 12-week delayed reference values plus a daily live rotation. Live values need Essential or above.
• Design Studio tools (draft, cost, compare) use one Suite run each; a compare run that finds nothing it can price is refunded.
• PACKIQ agents use PACKIQ credits. The Trade Exchange needs a Business or Corporate Exchange plan to send RFQs, with a monthly limit.
• One RFQ or quote request reaches at most 3 suppliers; your identity is shared only after a supplier responds.
• Design Studio costs are material benchmarks from PackIndex indices. They exclude print, finishing, tooling and freight, and are not supplier quotes.
• Values are indicative reference benchmarks, not procurement or financial advice. Cite them as "PackIndex" with their as-of date.

Privacy and disconnecting

PackIndex receives only the inputs your assistant sends to a tool — never your chat history, memories or files. Access tokens last one hour; refresh tokens are stored as one-way hashes. Disconnect any assistant in the portal under Settings → MCP Access. Read the full privacy policy and terms of use.

Support

Questions or problems with the connector: support@opnplatform.com. Please include the assistant you use and the time of the request. Operated by Polimex Trade Inc., 10225 Yonge St, Richmond Hill, ON L4C 3B2, Canada.
