MHR-CFW is a domain-fronting relay that routes traffic through Google Apps Script and Cloudflare Workers to bypass deep packet inspection.
The tool addresses network filtering by disguising traffic as ordinary Google requests while secretly routing it through Cloudflare Workers infrastructure. It works by running a local HTTP proxy on your computer that intercepts browser traffic, sends it through Google-facing infrastructure so network monitors see only allowed domains like www.google.com, and then fetches the actual destination through a deployed Cloudflare Worker before returning the response through the same hidden path. This approach keeps the real destination concealed inside the relay request while the filter observes normal-looking Google traffic.
The project suits users operating in environments with restrictive network filtering who need to access blocked content. It requires setting up three components: a Cloudflare Worker, a Google Apps Script relay, and a local Python proxy client. The setup involves deploying code to both Cloudflare and Google's platforms, configuring authentication credentials, and then running the local relay. The tool integrates with existing proxy clients like v2rayN or browser extensions such as FoxyProxy for transparent usage. Users should note that the README provides a PyPI mirror option for environments with restricted direct package access.
Development activity shows consistent maintenance with regular updates to core functionality and deployment documentation. The project includes setup wizards and configuration helpers that reduce initial friction for new users. Documentation is provided in multiple languages to serve a broader audience. The codebase demonstrates attention to security practices, particularly around credential handling and authentication key management.
