Use Caution4.8High Risk

inquisitor is a well-architected MCP server for hypothesis-driven problem-solving with appropriate security controls. Code is clean, permissions align with purpose (web search, codebase analysis, file I/O), and sensitive operations are properly guarded (SSRF protection, path traversal sanitization, parameterized SQL). Minor code quality observations around exception handling do not materially impact security. Supply chain analysis found 10 known vulnerabilities in dependencies (0 critical, 7 high severity). Package verification found 1 issue.
