Handrails

This Replit MCP server adds a development banner notification when Replit projects are accessed outside their native environment. The implementation detects when a Replit-hosted application is being viewed in development mode from an external context and automatically injects a banner at the top of the page to inform users of the development status. This is particularly useful for developers working on Replit projects who need to provide clear visual indicators to users when they're interacting with development versions of applications, helping distinguish between production and development environments and managing user expectations during the development process.
