mcp-boilerplate-node

The server uses `process.env` for sensitive configurations (e.g., API keys for observability, feature flags), which is a good practice. Input validation for tools is enforced through Zod schemas, mitigating common injection vulnerabilities. Request body size is limited to 4MB using `raw-body`. OpenTelemetry integration is present but optional, and tracing context extraction (e.g., `traceparent` header) is standard for distributed tracing. No hardcoded secrets or explicit 'eval' statements were found. The system architecture involves exposing API endpoints, so deployment environment and external access controls (e.g., authentication) would be crucial for a production setup, but this boilerplate itself does not inherently introduce severe risks.
