TL;DR AI
2 min readKey summary
A Hacker News discussion says Claude Desktop appears to use a native messaging bridge that was not clearly disclosed.
The bridge can connect a browser to a local Claude instance and local tools, which raises security concerns.
Undisclosed native messaging could let a browser trigger commands on a user’s machine, increasing risk.
The issue has prompted questions about Anthropic’s transparency and disclosure practices for local AI apps.
