What's Wrong?

Cowork Live Artifacts hardcode ~/Documents/Claude/Artifacts as mount path, ignoring user-configured folder and breaking macOS privacy controls

Problem Statement

Cowork Live Artifacts always attempt to mount to ~/Documents/Claude/Artifacts/<artifact-name>, regardless of which folder the user has connected in the Cowork session. This causes two compounding issues:

1. The mount path is hardcoded and cannot be changed via any setting or config file
2. On macOS, virtiofs cannot stat ~/Documents without explicit "Documents Folder" privacy permission granted to Claude — an all-or-nothing permission that grants access to the entire Documents folder

Users who store their Claude working directory outside of ~/Documents (e.g., ~/Claude/) have no way to use Live Artifacts without granting broader filesystem access than they are comfortable with.

Workarounds Attempted

• Deleting and recreating the Live Artifact: does not resolve, same path is used
• Creating a symlink from ~/Documents/Claude/Artifacts to ~/Claude/Artifacts: virtiofs fails with "operation not permitted" before it can follow the symlink
• Searching config files (~/Library/Application Support/Claude/, ~/.claude/): no stored path reference found, confirming the path is hardcoded in the app or stored server-side

Suggested Fix

Mount the Live Artifact folder relative to the user-connected Cowork session folder, not a hardcoded ~/Documents path. This is consistent with how the Code tab already handles folder selection.

Environment

• OS: macOS
• Claude Desktop version: latest (April 2026)
• Feature: Cowork Live Artifacts

What Should Happen?

Cowork should mount the Live Artifact folder relative to the folder the user connected in the session, not a hardcoded path under ~/Documents.

Error Messages/Logs

RPC error: failed to mount /mnt/.virtiofs-root/shared/Users/<username>/Documents/Claude/Artifacts/<artifact-name> as .artifacts/<artifact-name>: source path is not accessible: stat /mnt/.virtiofs-root/shared/Users/<username>/Documents/Claude/Artifacts/<artifact-name>: operation not permitted

Steps to Reproduce

1. Set up Claude working folder at ~/Claude/Artifacts (outside ~/Documents)
2. Open Cowork and connect ~/Claude/Artifacts as the session folder
3. Create or open a Live Artifact
4. Observe that Cowork ignores the connected folder and attempts to mount ~/Documents/Claude/Artifacts/<artifact-name> instead
