MCP_Architecture

The project is exceptionally security-conscious, dedicating a full document (02-security-architecture.md) to comprehensive security patterns. It details STRIDE threat modeling, multi-layered defense (Network, Auth, AuthZ, Application, Audit), and mitigations. Code examples explicitly demonstrate secure practices like JWT/JWKS validation, HMAC for integrity, parameterized queries to prevent SQL injection, path traversal prevention, command injection prevention using `subprocess.run` with argument lists, and robust input validation with Pydantic. It also mandates security headers, restrictive CORS, audit logging with sensitive data redaction, and recommends various security testing tools (Bandit, Safety, Semgrep, OWASP ZAP, Burp Suite). Hardcoded secrets are explicitly avoided in deployment configurations via environment variables or secret managers. The strong emphasis on security throughout the documentation and examples makes this a very well-secured architecture.
