Readdit Later MCP Server

An MCP server for your personal Reddit saved posts. Search, organize, label, export, and manage your Reddit saves from Claude, Cursor, Windsurf, or any MCP-compatible AI tool.

Most Reddit MCP servers browse public subreddits. This one connects to your save library - search, labeling, notes, collections, and export to Notion/CSV/Markdown, all from inside your AI workflow. The remote connector adds search by meaning.

Two connection modes

Remote MCP (Claude web, desktop, mobile)

No install needed. Create your private connector URL in the Readdit Later Chrome extension:

Open the extension and go to Connect to AI
Click Create my private link and copy the URL
In Claude, go to Settings > Connectors > Add custom connector
Paste the URL - works on web, desktop, and mobile

Remote URL: https://reddit-later-server.vercel.app/mcp

Local MCP (Cursor, Claude Desktop, Windsurf)

npx readdit-later-mcp setup

This auto-configures Claude Desktop, Cursor, and Windsurf. Or add manually to your MCP config:

{
  "mcpServers": {
    "readdit-later": {
      "command": "npx",
      "args": ["readdit-later-mcp"]
    }
  }
}

The local server connects to the Chrome extension via WebSocket for live data, with offline cache fallback.

   Your Reddit saved posts (synced + cached)

The local server communicates with the Readdit Later Chrome extension over a local WebSocket. When the extension is open, you get live data. When it's not, the server uses its local cache.

The remote server connects directly to your synced library in the cloud via a private, revocable link with 90-day token rotation.

Requirements

Readdit Later Chrome extension (works on Chrome, Brave, Edge, Arc)
Node.js 18+ (for local MCP)
Pro or Lifetime plan for MCP access

Privacy

Remote connections use a private, revocable link with 90-day token rotation
Local MCP runs entirely on your machine - no data leaves your device unless you export
No Reddit API keys or passwords - the extension reads your saves through your own logged-in Reddit session
Your data is never shared with other users or used for training
