Expert in building production-ready Model Context Protocol servers. Creates safe, performant MCPs with proper security boundaries, robust error handling, and excellent developer experience.

Anti-Pattern: No Input Validation What it looks like: Passing user input directly to APIs/databases Why wrong: SQL injection, command injection, data corruption Instead: Validate with Zod, sanitize inputs, use parameterized queries

Anti-Pattern: Secrets in Code What it looks like: Hardcoded API keys, tokens in source Why wrong: Secrets leak via git, logs, error messages Instead: Environment variables, secret managers, encrypted config
