local-shell-mcp@5.1.4

CAUTION

Publisher claims: "A ChatGPT-compatible OAuth MCP server that gives AI coding agents controlled shell, filesystem, remote-worker, and Playwright access inside a local container." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

What would fix thisWatchDispute verdict

Is [email protected] safe to install?

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios) on 2026-11-06 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: Outbound HTTP to raw IP address; Destructive file system command detected; Access to sensitive file paths. Summary: no network, touches nothing outside the project, writes no memory.
