Hey everyone,
I've been working on a project that involves using uvx to launch scripts for MCP server execution and some basic CLI tasks. Everything works perfectly on my personal computer, but I'm encountering a problem on my work laptop.
Microsoft Defender keeps flagging every command I run with uvx as suspicious, indicating that the application is new or recent, which prevents me from executing scripts that I know are safe and part of my own codebase.
Has anyone else experienced this issue? I'm looking for any practical workarounds, like whitelisting the binary or maybe signing the code, or is it just a waiting game until Defender decides to trust uvx? I understand there are company policies at play, but I'm hoping for some tips to get around this situation.
Any help would be greatly appreciated! Thanks!

You might want to check if there's a way to whitelist the uvx binary on your work computer. Sometimes, workplaces have settings to allow specific programs that are necessary for your work. It could also help to talk to your IT team about this—they might have solutions ready for such situations.
If IT is unhelpful, consider signing the code for uvx. It could give it more credibility in Defender's eyes.
It might just be a matter of time until Microsoft Defender updates its definitions and starts recognizing uvx as safe. In the meantime, checking the settings for Defender to see if you can make temporary allowances could be beneficial too.
I've had similar issues before, and it usually resolves itself eventually. But if you need a quicker fix, definitely consider asking for an exception.
True, but don't forget that you can always look into alternative methods to run your scripts locally while you sort this out.
Yeah, I've found that sometimes IT departments can be more helpful than you'd think. Just make sure to explain the context of your work so they can get on board with helping you out.
