Before you install Webclaw

AgenticMart scanned Webclaw on Nov 5, 2026 with automated checks for hidden code, known-malicious packages, leaked secrets and vulnerable dependencies. The result covers one commit under our scan policy, so review what access you give it and check any advisories shown here.

What it can access

  • An MCP server is a program your AI app starts and talks to. A local one runs with your user's permissions: it can see the files, environment variables and network your account can.
  • Based on its description and topics, it likely needs to control a web browser (visit sites, fill in and submit forms).

Before you install

  1. Run it in a separate browser profile without your logged-in accounts.
  2. Pin the version you reviewed instead of always installing the latest release.
  3. Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.
  • Maintained by 0xMassi on GitHub, 2,416 stars and 239 forks. Popularity is not proof of safety.
  • Last code change: Oct 30, 2026.
  • Open-source license: AGPL-3.0.
