mcp@1.33.0
CAUTION· startup onlyPublisher claims: "Zero-install npx launcher for the RedDB MCP surface — fetches the matching red binary and spawns `red mcp` over stdio." Observed in sandbox: sends data to release-assets.githubusercontent.com.
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.
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 2026-11-11 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.
