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: 53/100 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
This server runs on the vendor's side, so there's no code for us to scan. You're trusting the vendor with whatever you send it.
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
Alternatives
Nothing from another maker does quite the same job yet.
