# devfeed-mcp

**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

```bash
claude mcp add devfeed-mcp -- npx devfeed-mcp
```

### Manual (any MCP client)

```json
{
  "mcpServers": {
    "devfeed-mcp": {
      "command": "npx",
      "args": ["devfeed-mcp"]
    }
  }
}
```

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

## Personalization

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

```yaml
# Platform usernames
hackernews: your-hn-username
reddit: your-reddit-username

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

# Keywords to match in titles
keywords:
  - "Claude Code"
  - "MCP server"
  - TypeScript

# HN users to follow
hn_follow:
  - tptacek
  - patio11

# Reddit subreddits for your digest
subreddits:
  - programming
  - ClaudeAI
  - LocalLLaMA

# Dev.to tags
devto_tags:
  - ai
  - typescript
```

See [example.devfeed.yaml](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.
