Before you start

ChatGPT adds a custom MCP server through Developer mode, which you turn on in settings. For the quickest setup, use Claude instead. You also need a paid Influesque plan or an active free trial. See Credits & limits.

Turn on Developer mode

In ChatGPT, open Settings -> Apps -> Advanced settings.
Turn on Developer mode.

Turning on Developer mode in ChatGPT settings — Settings -> Apps -> Advanced settings -> Developer mode.

Add Influesque

On the same screen, click Create app.
Enter a Name, for example Influesque.
Under Connection, keep Server URL selected and paste:

https://platform.influesque.com/mcp

Leave Authentication set to OAuth.
Tick I understand and want to continue, then click Create.

The New App dialog in ChatGPT Developer mode — Name it, paste the Influesque server URL, keep OAuth, tick the confirmation box, then Create.

Sign in and connect

After you click Create, ChatGPT shows an Add Influesque to ChatGPT screen.

Click Sign in with Influesque.
Sign in to your Influesque account and approve access.
ChatGPT returns to the app and Influesque is connected.

The Add Influesque to ChatGPT sign-in screen — Click Sign in with Influesque to connect your account.

Try it

In a new chat, make sure the Influesque connector is enabled, then ask:

Which creators has HelloFresh worked with? Include a link to each on Influesque.

ChatGPT calls Influesque and returns the brand's creator list with links back to the app. For more ideas, see Example workflows.

Troubleshooting

No Developer mode option. Look under Settings -> Apps -> Advanced settings.
The tools are not used. Make sure the Influesque connector is enabled for the chat, then ask again.
Out of credits. Top up or upgrade in the app under Settings -> API & MCP.
