Show HN: Alfa, always up-to-date code docs when using AI code editors

My friend and I have been working on Alfa, which allows people to bring in the latest code docs into their prompts when using AI code editors like Cursor, Windsurf, and any editor that supports MCP (model context protocol).

Alfa maintains a database of code docs that we scrape and embed and make it available to user via MCP. Currently focused on rapidly growing out our code docs coverage but we have a few up right now so users can test it out.

We made this after running into lack of context issues when using Cursor with claude 3.5 (and 3.7), as well as gemini 2.5 pro. For example, I was working on a side project that used better-auth (an authentication package) but claude 3.5 suggested using NextAuth (a more popular package that I'm not a fan of), and when I prompted that I specifically wanted to use better-auth, it told me it's not familiar with it [1]. I know that Cursor adds stuff like web search calls and sometimes it does correctly fetch the necessary context, but I wanted something to just work always, no matter the LLM by providing the necessary context.

Would appreciate any feedback. Thanks!
