Avoid destructive commands, credential rotation, billing changes, or security relaxations without a rollback plan.

What this error means

Cursor sandbox blocks all access to files matching .git* patterns — uv run fails because uv recreates .git marker files every time is a Cursor failure pattern reported for developers trying to fix cursor sandbox blocking uv run commands due to .git* file pattern restrictions. Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.

Why this happens

The Cursor sandbox blocks all access to files matching .git* patterns, treating them as git operations. uv recreates .git marker files every time it runs, causing consistent failures. Removing the files doesn't work because uv recreates them. This is a Cursor sandbox design issue, not a uv bug.

Common causes

Cursor's sandbox mode treats .git* file access as git operations and blocks them. Python developers using uv (fast package manager) find that uv recreates .git marker files on every run, causing repeated failures. This is a sandbox design conflict with legitimate development workflows.
