mcp-toolkit

The module itself employs good practices like TypeScript and Zod for input validation. However, the overall security highly depends on how developers implement their MCP tool, resource, and prompt handlers. Malicious or insecurely written handlers (e.g., executing unsanitized user input) could introduce vulnerabilities. The use of `spawn` with `npx -y` for the DevTools inspector is noted but is a common pattern for development tools and not inherently malicious within this context. No hardcoded secrets were found; sensitive configurations are expected to be provided via environment variables.
