CAUTION

Publisher claims: "Build secure MCP (Model Context Protocol) servers from plain Python functions." 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 2026-10-30 and scored it 59/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Refusal suppression; Authorization escalation language; Credential pass-through configuration. Summary: no network, touches nothing outside the project, writes no memory.
