validation +- Safe escaping of user-visible text fields +- Reusable static/class methods for field-level and form-level validation + +Intended to be used with Pydantic or similar schema-driven systems to validate and sanitize +user input in a consistent, centralized way. + +Dependencies: +- Standard Library: re, html, logging, urllib.parse +- First-party: `settings` from `mcpgateway.config` +
