Why this score
Installs in real projects: we can't search for this one (it has no fixed package name or address), so it's scored as a typical MCP server.
Popularity score: 48/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank
Security
Scanned Nov 4, 2026 at the PyPI package arc-free-skills@1.0.0, first 300 source files (it's a large repo), with Cisco's open-source skill-scanner.
What its code does:
- Uses dependencies without a pinned version A later version of a dependency could change what runs.pyproject.toml:15 and 5 more
A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
