biopb-mcp@0.7.2
CAUTIONPublisher claims: "Performing image analysis by visiting biopb endpoints" Observed in sandbox: no network, touches nothing outside the project, writes no memory.
Is [email protected] safe to install?
KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios) on 2026-10-28 and scored it 63/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Privileged sudo command; Pipe-to-shell pattern; Outbound HTTP to raw IP address. Summary: no network, touches nothing outside the project, writes no memory.
