The server demonstrates strong security practices for its use case. It strictly validates and trims all input prompts using Zod schemas, rejecting unknown fields to prevent unexpected behavior. API keys for LLM providers are exclusively sourced from environment variables, preventing hardcoding. Sensitive information in debug logs is redacted and truncated. The internal error handling classifies and manages LLM-specific errors, including authentication and rate limiting. Protocol-level safeguards ensure strict version negotiation and server initialization before processing requests, preventing premature interactions. There are no indications of 'eval' or malicious patterns directly processing user input. Dependencies related to templating engines (like Pug for HTML reports in dev tools) are not used for processing runtime user input in a way that would introduce injection vulnerabilities.
