Security Report

5.2

Moderate5.2Moderate Risk

grok-mcp is a well-structured MCP server that wraps the official xAI Grok CLI. Authentication is properly handled through environment variables (XAI_API_KEY) with secure defaults, and the codebase demonstrates good security practices including input validation via Zod schemas, proper error handling, and no hardcoded credentials. The server's permissions are appropriately scoped to its purpose: spawning the grok CLI, reading git diffs, and making network calls to the Grok API. Minor findings around error context and input validation do not materially impact security. Supply chain analysis found 4 known vulnerabilities in dependencies (2 critical, 2 high severity). Package verification found 1 issue.
