No deprecated ai-plugin.json
What the check finds
/.well-known/ai-plugin.json is present but the ChatGPT plugin format it belongs to is retired. MCP replaced it.
Why it matters for AI answers
The ChatGPT plugin format this file belongs to is retired, so no assistant uses it. A stale file can describe outdated endpoints and adds nothing for AI access.
How to fix it
- Remove /.well-known/ai-plugin.json and let the URL return 404 or 410.
- Shut down any API endpoints that existed only for the old plugin.
- If assistants should use site tools, look at MCP instead.
