Can't install MCP servers with deeplinks on Debian

Describe the Bug

on my debian 12 system, trying to get deeplinks to work to easily install MCP servers; Followed this guidance https://claude.ai/share/c1a66c8a-7ebc-4fbd-9dd0-788123a5a46b trying to get deeplinks working; when I click any of the deeplinks to install an MCP server, instead it creates a new text file with the filename consisting of the URL from the deeplink.

Steps to Reproduce

Install Cursor on Debian 12 and try clicking a deeplink like cursor://anysphere.cursor-deeplink/mcp/install?name=Playwright&config=eyJjb21tYW5kIjoibnB4IEBwbGF5d3JpZ2h0L21jcEBsYXRlc3QifQ%3D%3D

Expected Behavior

Should install the MCP server
