Learn how to connect Claude Desktop and other AI assistants to your Rapid Reader library using the Model Context Protocol (MCP).

#guide#integration#claude#mcp#ai

What is MCP Integration?

The Model Context Protocol (MCP) allows AI assistants like Claude Desktop to interact with external tools and services. With Rapid Reader’s MCP integration, you can ask Claude to add articles, research papers, or any text content directly to your reading queue.

This means you can be researching a topic in Claude, find something interesting, and add it to your reading list without leaving the conversation.

What You Can Do

With the MCP integration, Claude can:

  • Add content to your reading queue - Send URLs, articles, or text directly to your library
  • Query your library - Ask what you’re currently reading or search your collection
  • Track progress - Check your reading stats and update your position

Quick Setup Guide

Step 1: Generate an API Key

  1. Open Rapid Reader at rsvp.rapidreader.app
  2. Go to Settings (gear icon) > Account tab
  3. Scroll to API Keys section
  4. Enter a name like “Claude Desktop” and click Create Key
  5. Copy the key immediately - it won’t be shown again!

Step 2: Configure Claude Desktop

Add the following to your Claude Desktop configuration file:

macOS: ~/.config/claude/config.json Windows: %APPDATA%\Claude\config.json Linux: ~/.config/claude/config.json

{
  "mcpServers": {
    "rapid-reader": {
      "url": "https://rsvp-api.rapidreader.app/api/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY_HERE"
      }
    }
  }
}

Replace YOUR_API_KEY_HERE with the API key you copied.

Step 3: Restart Claude Desktop

After saving the config, restart Claude Desktop to load the MCP server.

Usage Examples

Adding Articles

Simply ask Claude to add content to your reading queue:

“Add this article to my reading list: https://example.com/interesting-article”

“Can you add the text below to my Rapid Reader queue? [paste text]“

Checking Your Library

You can ask Claude about your reading activity:

“What articles do I have in my reading queue?”

“What am I currently reading?”

“Show me my reading progress”

How It Works

When Claude sends content via the MCP integration:

  1. For free users: Content goes to a temporary cloud inbox (14-day TTL). When you open Rapid Reader, items are automatically imported to your local library.

  2. For Pro users with sync: Content is immediately added to your synced cloud library and appears across all your devices.

Security Best Practices

  • Name your keys descriptively - Use names like “Claude Desktop” or “Work Mac” so you know what each key is for
  • Revoke unused keys - If you stop using a key, delete it in Settings
  • Don’t share your keys - Each user should generate their own API key

Troubleshooting

”Unauthorized” Error

  • Verify your API key is correct
  • Ensure the key hasn’t been revoked in Settings
  • Check that the Authorization header format is Bearer YOUR_KEY

Content Not Appearing

  • Open Rapid Reader to trigger inbox sync (for free users)
  • Make sure you’re logged into the same account
  • Check the API Keys section to verify your key was created

”Upgrade Required” Error

Some advanced features may require a Pro subscription. Check the error message for details on which feature needs an upgrade.

Rate Limits

To ensure fair usage:

  • 100 requests per minute per API key
  • Content size limits: 5 MB per item (free), 20 MB per item (Pro)
  • Inbox limit: 10 pending items (free users)
