Hi Team,

We would like to connect the Outbrain Amplify API with ChatGPT. Is there a way to do this?

I have already tested connecting the MCP server to ChatGPT via a local proxy, but ChatGPT classifies this type of connection as unsafe.

ChatGPT Connector currently only supports MCP URLs with SSE endpoint. Is it possible to obtain an Outbrain MCP URL with the appropriate endpoint?

Thanks for your help!

Lena

I've reached out to our internal team to check the available information here and will get back to you, as soon as I receive any feedback.

Hi Lena,

I've just received feedback from our RnD team that you can connect ChatGPT and our API endpoint via http mode with developer mode in ChatGPT.

For that you can refer the docs, here: https://platform.openai.com/docs/guides/developer-mode

If you need additional information on the MCP from our side, please refer to the docs here: https://www.outbrain.com/help/advertisers/how-to-connect-to-our-model-context-protocol-mcp-server/
