mcp-typescript-sdk

The source code appears to follow good security practices. It extensively uses Zod schemas for input validation, which helps prevent malformed requests and potential injection vulnerabilities. Message parsing uses `JSON.parse`, which is safe for valid JSON. There are no explicit uses of `eval`, `child_process.exec`, or other dynamic code execution mechanisms. Sensitive information like MQTT credentials (username, password) are expected to be provided by the user during configuration and are not hardcoded. The SDK uses `nanoid` for generating unique IDs, which is cryptographically strong. MQTT 5.0 features are leveraged to enhance connection robustness. The error handling mechanism also appears to prevent excessive internal detail leakage. The `RELEASING.md` indicates secure npm publishing via OIDC, reflecting a general security awareness.
