Before you install Crab Agent Extension
Crab Agent Extension has not been scanned by AgenticMart yet. It has no open-source license we can detect, so it can only be scanned once the maintainer claims it. Until then, here is what it can likely access and what to check before you install it.
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 control a web browser (visit sites, fill in and submit forms).
- Based on its description and topics, it likely needs to run shell commands.
Before you install
- Run it in a separate browser profile without your logged-in accounts.
- Keep tool-call approval on, and run it in a container if you can.
- 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 Hert4 on GitHub, 9 stars and 2 forks. Popularity is not proof of safety.
- Last code change: Sep 30, 2026.
- No open-source license detected: check the repository before using it commercially.
