PackIndex MCP

Official MCP server for PackIndex by OPN, enabling AI assistants to access live packaging material prices, index history, carbon scores, and forecasts. It supports design studio integration for packaging specs, PACKIQ agent execution, and Trade Exchange RFQs, allowing users to check supplier quotes, adjust contract prices, and find cheaper options using their own OPN plan data.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http packindex-mcp https://opnplatform.com/api/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add packindex-mcp --url https://opnplatform.com/api/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable packindex-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "packindex-mcp": {
      "url": "https://opnplatform.com/api/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration

{
  "mcpServers": {
    "packindex-mcp": {
      "type": "streamableHttp",
      "url": "https://opnplatform.com/api/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start packindex-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "packindex-mcp": {
      "type": "http",
      "url": "https://opnplatform.com/api/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http packindex-mcp https://opnplatform.com/api/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

{
  "mcpServers": {
    "packindex-mcp": {
      "url": "https://opnplatform.com/api/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "packindex-mcp": {
      "serverUrl": "https://opnplatform.com/api/mcp"
    }
  }
