I was looking around for an MCP server that could connect Anna&#x27;s Archive to Claude Desktop, as I wanted to be able to search and download books directly through the interface.I couldn&#x27;t find any public implementations, so ended up building one myself.What it does?- It searches Anna&#x27;s Archive by keywords.
- It downloads books from search results.
- It works directly in Claude Desktop through MCP.Check out the repository&#x27;s README for detailed installation and configuration instructions.The code is fully open source and builds run on GitHub Actions for transparency.I figured I&#x27;d share, since I couldn&#x27;t be the only one wanting this functionality!

Biomni: A General-Purpose Biomedical AI Agent

I have a large collection of music files gathered over the years, so I was sorely missing a decent offline music player that can serve as a frontend for the collection. I tried several Mac apps over the years, but since streaming music is mainstream now, there aren&#x27;t good offline music players that meet my needs. So I spent the last 3 months building Petrichor! The idea is to solve my problem and learn Swift UI development along the way, while giving back to the community with this open-source project! Here&#x27;s a list of features it has, with more getting added in future;- Everything you&#x27;d expect from an offline music player!- Map your music folders and browse your library in an organised view.- Create playlists and manage the play queue interactively.- Browse music using folder view when needed.- Pin anything (almost!) to the sidebar for quick access to your favourite music.- Navigate easily: right-click a track to go to its album, artist, year, etc.- Native macOS integration with menubar and dock playback controls, plus dark mode support.- Search quickly through large libraries containing thousands of songs.The app is still in alpha, so things may look unpolished, but I&#x27;ve been testing the alpha builds for the past few weeks and fixing issues as I find them for v1 release. I welcome any feedback (and contributions!) on GitHub repo. Please give it a try and let me know what you think!

Hey HN,I&#x27;m a solopreneur and run a web design agency.I create open-source apps, but I also work as a freelancer and designer. I was accepting any new freelance project via forms on my agency website.I was using Typeform, but as time went by and more people submitted forms, it got more and more expensive. That time, I thought to use Google Form, but it was way too blocky and looked very unprofessional on my agency website.So I thought to build my own forms for my own usage, and it turns out it almost doubled form submissions and inquiry calls.I was happy, so I thought to build it for everyone and make it open-source.I added AI functionalities using Vercel AISDK. I can generate forms almost instantly using AI and also added analytics AI so that users can talk with their forms—more like talk with their analytics data.I&#x27;ve been building this publicly, sharing updates on my X account (preetsuthar17)I hope this product will be as helpful to you as it was for me. Would love your feedback plsPreet
