How to Build a Hacker News MCP Server with FastMCP 3.0 (Tools, Resources, Prompts & Lifespan)

I've been building MCP servers for a few weeks now. A calendar tool, a document parser — useful, but neither of them felt like something I'd actually open every day. Then I thought about Hacker News. I check it constantly, but half the time I just want someone to tell me what actually matters today without me having to dig through 30 tabs. That's when it clicked: instead of browsing HN, I could give Claude the ability to do it for me — fetch stories, search by topic, pull comments, and generate a curated digest on demand. This is that project. Along the way it became the best introduction to FastMCP 3.0 I've written — covering tools, resources, prompts, lifespan management, async HTTP, and dual transport in one real-world build. If you've been looking for a project that exercises all of FastMCP's major features without artificial complexity, this is it.
