CAUTION

Publisher claims: "The most AI-optimized GitHub MCP server: 112 tools, code-first architecture (98% token reduction), compact responses (80-97% smaller). Built for efficient AI development." 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 72/100 (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; Credential pass-through configuration. Summary: no network, touches nothing outside the project, writes no memory.
