hanzo-mcp@0.15.21
CAUTIONPublisher claims: "The Zen of Hanzo MCP: One server to rule them all. The ultimate MCP that orchestrates all others." 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 2026-11-01 and scored it 65/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Access to sensitive file paths. Summary: no network, touches nothing outside the project, writes no memory.
