Controlling link punch-out behavior in ChatGPT Apps

OpenAI Developer Community June 4, 2026

Is there another way to control the link punch-out when it comes to the ChatGPT Apps? This is referring to the full-screen button and the redirect from clicking the app name when it’s rendered inline.

Right now, they are controlled by ui.domain, but this is not ideal for cross-platform applications. For example, Claude requires that the ui.domain be a hash of the MCP URL, such as mcp.example.com/mcp, or the app will just refuse to render. But I don’t want ChatGPT to redirect to my MCP URL; I want it to redirect to my homepage at www.example.com.

Thanks for the help!
