ChatGPT
The Nifty plugin in the ChatGPT directory is under review by OpenAI and doesn't have our latest tools, including item editing. Until the review is complete, use a custom connection as described below. If you already installed the plugin, uninstall it: open its plugin page, select the ⋯ menu, and choose Uninstall.
Add a custom connection
Custom connections require Developer mode, which is available on paid ChatGPT plans. On Business, Enterprise, and Edu workspaces, an admin must allow custom MCP connections first.
Add Nifty
Open ChatGPT Plugins, select the + button, and create a new connection with:
Name: Nifty (Custom)
Server URL:
https://api.nifty.ai/api/mcpAuthentication: OAuth
Select Create, then sign in to your Nifty account when prompted.
Troubleshooting
Missing a tool, or a tool that fails with "Tool not found"? New tools are released regularly, but ChatGPT keeps the tool list from when the connection was created. Uninstalling and reinstalling isn't enough; delete the connection and create it again:
Open your plugins, select the ⋯ menu next to Nifty (Custom), and choose Manage.
On the connection page, select the ⋯ menu at the top right and choose Delete.
Add the custom connection again from scratch, then start a new conversation.
If you're using the Nifty plugin from the directory instead, switch to a custom connection as described above.
Known issues
Photos don't display in ChatGPT Chat. The connector sends them, but Chat discards them, so you'll see the photo count and indexes without the images themselves. Recreating the connection doesn't help.
Photos do display in ChatGPT Work, so switch to Work if reviewing photos matters to you. Work needs a paid ChatGPT plan and isn't available on the free plan. Claude shows photos in ordinary conversations.
See Connect via MCP for what the assistant can do and the requirements.
