Before you install Sidecar

What it can access
- An AI agent decides its own next steps and calls whatever tools you give it, so its risk depends on the access you grant.
- Based on its description and topics, it likely needs to read and write files on your machine.
Before you install
- Point it at one project folder, never your home directory.
- Pin the version you reviewed instead of always installing the latest release.
- Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.
- Maintained by marcus on GitHub, 1,094 stars and 81 forks. Popularity is not proof of safety.
- Last code change: Oct 8, 2026.
- Open-source license: MIT.
