mcp-supply-audit@0.1.0

CAUTION

Publisher claims: "Enables static, read-only auditing of MCP servers’ registry entries, package metadata, client configurations, and tool definitions for supply-chain security indicators. It returns merged reports with transparent skipped checks and never executes the inspected code." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

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: Pipe-to-shell pattern; Pipe-to-shell pattern; Pipe-to-shell pattern. Summary: no network, touches nothing outside the project, writes no memory.
