Security Report

5.2
Moderate5.2Moderate Risk

gmail-mcp is a well-architected Gmail MCP server with strong security fundamentals. Authentication uses OAuth 2.1 with PKCE, tokens are properly stored in encrypted KV namespaces, and permissions are narrowly scoped to the Gmail API. The codebase demonstrates careful attention to security details including CRLF header injection prevention, charset handling, and CSRF protections. Minor code quality observations around error handling breadth do not materially affect the security posture. Supply chain analysis found 4 known vulnerabilities in dependencies (0 critical, 3 high severity).
