vidlens-mcp@1.6.0
CAUTIONPublisher claims: "Turn a public video into an evidence table an LLM can read: timecoded transcript, sampling sheets and AudioSet sound events, downloading only the bytes it needs." 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 2026-10-26 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: Pipe-to-shell pattern; Destructive file system command detected; Python subprocess execution detected. Summary: no network, touches nothing outside the project, writes no memory.
