Security Report

5.6
Moderate5.6Moderate Risk

Sibyl is a keyless deep-research MCP server whose visible code (composition root, CLI, and tool definitions) shows no malicious patterns, hardcoded secrets, or shell injection. The main concerns are opt-in third-party egress through the Jina Reader fallback and an API key accepted as a plain CLI argument, both low severity, and the permissions shown match the stated research purpose. Parts of the codebase were truncated, so the score reflects only the visible files. Supply chain analysis found 2 known vulnerabilities in dependencies (1 critical, 0 high severity). Package verification found 1 issue.
