Rss Feeder

rss-watcher-cli

A fast, TypeScript-native RSS/JSON feed reader with a built-in MCP server. Built on Bun and SQLite.

Why rss-watcher-cli over blogwatcher-cli?

| | rss-watcher-cli | blogwatcher-cli | | ------------------------ | ------------------------------------------------------------------------------------ | --------------- | | Runtime | Bun (fast, single binary) | Go | | MCP server | ✅ Built-in (mcp command) | ❌ | | AI-agent integration | Tools for adding feeds, pulling articles, marking read/unread — all callable by LLMs | None | | Transport | stdio | N/A | | Feed formats | RSS & JSON Feed | RSS | | HTML sanitization | Strips tags & limits content length automatically | Raw HTML |

The headline feature is the MCP server: run rss-watcher-cli mcp and any MCP-compatible client (Claude Desktop, Cursor, custom agents) can manage your feeds and read articles programmatically.
