Show HN: Pizza Bot – An inbox for AI agents that work in the background

Hi HN - long-time lurker (since 2012!), first time poster. Pizza Bot is a self-hosted desktop app for Mac, Windows, and Linux that runs AI agents in the background and exposes them through an email-like UI. Finished work shows up in Unread, and anything waiting on your approval shows up in Action. I

I built an MCP Gateway that can run MCPs directly from Git repos — feedback?

I've been building an MCP Gateway called Yūsetu and would love some feedback from people who are actually using MCPs. Stupidly Simple and Straight Forward MCP Gateway. The basic idea is pretty simple: put multiple MCPs behind a single endpoint and make them easier to manage. One
