Hn

A personalized dev community reader for AI assistants. Like RSS, but for Hacker News, Lobsters, Reddit, and Dev.to — and your AI does the reading for you.

Define your interests once, then ask your AI assistant what's happening across all your communities in a single conversation.

Quick Start

Claude Code / Claude Desktop

claude mcp add devfeed-mcp -- npx devfeed-mcp

      "command": "npx",

    }

}

No API keys. No accounts. No config required to start.

Create ~/.devfeed.yaml to personalize your experience:

# Platform usernames

reddit: your-reddit-username

# Topics (matched across all sources)
topics:
  - ai-agents
  - developer-tools
  - open-source

  - TypeScript

See example.devfeed.yaml for a full example.

All data stored locally in ~/.devfeed/. No server, no telemetry.

Why This Exists

I've had accounts on these platforms for years. The reading experience across all of them is fragmented — different UIs, no unified notifications, no way to filter by what I actually care about.

This gives my AI assistant read access to all my dev communities so I can stay on top of conversations without context-switching between four browser tabs.
