Connect ChatGPT

Use the Mighty Ads plugin if MightyAI has supplied an installation link available to your account. Otherwise, the custom MCP setup below connects ChatGPT to the same MightyAI server.

Custom MCP setup depends on the controls available in your ChatGPT account. These steps do not require a public Mighty Ads marketplace listing.

Add the connection

Open setup

Open Plugins in ChatGPT’s sidebar, or open ChatGPT Plugins.

Enter the connection details

Name it MightyAI and enter this Server URL:

https://api.mightyai.app/mcp

ChatGPT custom MCP form filled with MightyAI, the production server URL, and OAuth authentication. — Enter MightyAI as the name and https://api.mightyai.app/mcp as the Server URL. Authentication should be OAuth.

Check OAuth settings

Keep Authentication set to OAuth. Open Advanced OAuth settings and check that Registration method is Client Identifier Metadata Document (CIMD). ChatGPT can discover and select this automatically.

ChatGPT advanced OAuth settings showing Client Identifier Metadata Document (CIMD) for the MightyAI MCP server. — In Advanced OAuth settings, check the CIMD registration method. You do not need to enter your own client ID or client secret for this setup.

Check the result

Review ChatGPT's connection notice, select I understand and want to continue if you agree, then select Create as a plugin.

Choose your workspace

Install the resulting plugin and complete MightyAI browser sign-in. Choose the workspace containing your brand.

If your account does not show custom MCP controls, contact MightyAI for an available setup path.

Use it in a chat

Start a new chat, type @, and select your installed MightyAI plugin. Ask:
