CAUTION

Publisher claims: "Local-first, no-API-key search MCP server. Multi-engine web search, smart fetching, document reading." Observed in sandbox: calls astral.sh only, 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 2026-10-29 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; Access to sensitive file paths; Direct script execution from GitHub raw URL. Summary: calls astral.sh only, touches nothing outside the project, writes no memory.
