I built this on my 35-minute BART ride to SF using my phone as the IDE (and a couple of hours of feature creep/testing). It's a combination MCP server + HTTP proxy that converts web content to markdown on-the-fly.
Key features:
* HTTP/HTTPS proxy with automatic HTML to markdown conversion * Token counting and caching to stay efficient * Content negotiation (only converts when Accept: text/markdown) * MCP server * JavaScript rendering for dynamic sites
Let me know what you think!
