How to manually/offline install Claude Agent for Xcode?

Hi everyone,

I'm working in a strictly offline (intranet) environment and cannot use the standard online installation process to download and install the Claude Agent for Xcode.

What I've tried: I manually copied the Agent binary/folder from an online machine to the following path: ~/Library/Developer/Xcode/CodingAssistant/Agents/Versions/26.3/claude

The Issue: Even though the files are in the correct directory, Xcode fails to recognize the agent. It doesn't appear in the settings, and the Coding Assistant remains unavailable.

Questions:

Is there a specific metadata file (e.g., a .plist or .json index) that needs to be updated for Xcode to "see" the manually added agent?

Are there any code signing or quarantine issues (like xattr) that need to be addressed when moving the agent between machines?

Does anyone know if there are other dependencies or cache folders (besides ~/Library/Developer/Xcode/CodingAssistant/) that need to be synchronized?

Environment:

macOS: 26.3 (25D122)

Xcode: 26.3 (17C519)

Any guidance on the manual registration process for these agents would be greatly appreciated. Thanks!

Thanks for this great post!

I think the Claude Agent for Xcode requires an active internet connection to communicate with Anthropic's servers and is not designed for native offline operations at this time.

However I think you should file an enhancement request for this.

If you'd like us to consider adding the necessary functionality, please file an enhancement request using Feedback Assistant. Once you file the request, please post the FB number here.

If you're not familiar with how to file enhancement requests, take a look at Bug Reporting: How and Why?
