ChatGPT has two routes to the same data. The Porter Metrics app in ChatGPT’s app directory works on any plan with apps. The Porter MCP gets every new tool the day Porter ships it, on Business, Enterprise and Edu workspaces.
Porter Metrics app: in ChatGPT, open Apps, search “Porter Metrics”, click Connect and sign in with the Google account you use in Porter.
Porter MCP:
- Open ChatGPT on the web and go to Plugins.
- Click +, then Add custom MCP server.
- Name it
Porter and paste https://mcp.portermetrics.com/mcp under Connection. - Choose OAuth, tick “I understand and want to continue” and click Create as a plugin.
- Sign in with the Google account you use in Porter.
Pro accounts can add it with read access only, per OpenAI’s custom MCP server guide.
