Problem Found

I discovered that whenever fastapps dev is run, local asset server is blocking Widgets to be properly rendered in ChatGPT UI as CSP & CORS settings are not properly configured.

changing the remote URL configuration from :

  • cloudflare tunnel url for mcp server ( random-subdomain.trycloudflare.com/mcp )
  • localhost:4444 for asset server

to :

  • cloudflare tunnel url for mcp server ( random-subdomain.trycloudflare.com/mcp )
  • same cloudflare tunnel url for asset server ( random-subdomain.trycloudflare.com/assets )

will resolve the issue.

Changes made

  • updated fastapps mcp server config to proxy asset server
  • (chore) aggregated template flags for widget creation as --template
  • (chore) updated url shown with /mcp url endpoint whenever dev server is ready - so that it's easier to copy and paste.

CORS resolve

critical fix on dev asset server
