Coverage

Startup only; authenticated tool behavior not tested.
Tested
server startup over stdio (initialize sent) · every file read, file written and host contacted by what ran
Not tested
the tool list (the server exited before answering) · what the tools do when called with real credentials

What this means for the label: Caution here covers what ran. The server's tools were not exercised with a real credential, so nothing about their behavior is asserted; the credential summary below says what to do with that.

Before you give it your token

It will ask for
no credential variables read in the code
Where it talks to
no vendor host named in the codeAlso githubusercontent.com — not the publisher's domain; check what for before connecting.
What the honeypot saw
no credential files read · contacted release-assets.githubusercontent.com (undeclared)
What we could not test
the tool list (the server exited before answering) · what the tools do when called with real credentials

Find out what these hosts are first. In the honeypot it contacted release-assets.githubusercontent.com, which nothing in the package names as its own. If that is the vendor's service, fine; if you cannot place it, do not connect it.

$vet-skills run --net release-assets.githubusercontent.com -- npx -y @reddb-io/mcp

Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

Is [email protected] safe to install?

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios; startup only; authenticated tool behavior not tested) on 2026-11-13 and scored it 54/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Pipe-to-shell pattern; Direct script execution from GitHub raw URL. Summary: sends data to release-assets.githubusercontent.com.
