Fix: Resolve 301 redirects and 404 errors when serving HTML files

[escudero89]

Problem

The pnpm run serve command was returning 301 redirects followed by 404 errors when accessing HTML files like todo-2d2b.html. This happened because the serve package's cleanUrls feature automatically redirects filename.html to filename (removing the extension), but the actual files have .html extensions.

Using it in MacOS (15.7.1 (24G231)).

Solution

• Added assets/serve.json configuration file with {"cleanUrls": false} to disable automatic HTML extension removal
• Updated the serve command in package.json to use the configuration file

Changes

• Added: assets/serve.json - disables cleanUrls feature
• Modified: package.json - updated serve command to reference the config file

Result

• ✅ HTML files now return 200 OK instead of 301 → 404
• ✅ Direct access to files like http://localhost:4444/todo-2d2b.html works correctly
• ✅ No breaking changes to existing functionality

This fix ensures that the static file server works as expected when serving the built widget assets for the MCP servers.
