• Update tags: Replace all tags on a document
• Add a specific tag: Add a single tag to a document
• Remove a specific tag: Remove a tag from a document
• Bulk tagging: Apply tags to multiple documents at once

Advanced Search

Powerful filtering options for finding exactly what you need:

• query: Search text

Video Features

Access and interact with videos saved in your Readwise Reader:

Video Listing and Details

• List all videos: Browse videos from YouTube, Vimeo, and other platforms
• Get video details with transcript: Access complete metadata and time-synced transcripts

Video Highlights

• Create highlight with timestamp: Mark important moments in videos
• Get video highlights: Retrieve all highlights for a video, sorted by timestamp

Video Playback Position

• Update playback position: Save your current position for later resuming
• Get playback position: Resume where you left off

How Transcript Access Works

The video transcript feature:

1. Extracts the time-synced transcript from the video's HTML content
2. Parses timestamp and text pairs
3. Returns transcript as an array of segments with timestamps

This allows you to:

• Search for specific content within videos
• Create highlights at precise moments
• Jump directly to important points
• Reference video content with exact time context

Content Management

Save, update, and delete content:

• Save new content: Add URLs, articles, or custom content to your library
• Update document: Modify title, author, summary, tags, and more
• Delete document: Remove content (with safety confirmation)

Bulk Operations

Efficiently manage multiple documents at once:

• Bulk save: Save multiple URLs/content items
• Bulk update: Update multiple documents
• Bulk delete: Remove multiple documents
• Bulk tag: Apply tags to multiple documents

Safety Confirmations

All bulk operations and deletions require explicit confirmation to prevent accidental data loss:

• Single document deletion: Requires confirmation parameter
• Bulk operations: Require specific confirmation strings

These confirmations act as a "human in the loop" safety mechanism.

API Status

Check the API status and rate limit information at any time.

        "READWISE_API_KEY": "your_api_key_here"
      }
    }
  }
}

docker run -p 3001:3001 -e READWISE_API_KEY=your_key readwise-mcp

Troubleshooting

Token Issues

If you encounter authentication issues:

1. Verify your Readwise API token is still valid at https://readwise.io/access_token
2. Reset authentication by deleting stored credentials:

   rm ~/.readwise-mcp/credentials.json
   

3. Restart and try connecting again

Connection Issues

If the server cannot connect:

1. Ensure the server is running (if manually started)
2. Check that port 3001 is not being used by another application
3. Restart your AI client (Claude Desktop, Cursor, etc.)

Rate Limiting

The server includes built-in rate limiting. If you encounter rate limit errors:

1. Wait a few minutes before trying again
2. Reduce the frequency of requests
3. Check the rate limit headers in responses

Video-Specific Issues

1. Missing transcripts: Not all videos have transcripts. YouTube videos typically have the best support.
2. Transcript quality: Transcripts are from the video platform and may contain errors.
3. Timestamp inconsistencies: Different platforms use different formats; the API normalizes when possible.
4. Playback position not updating: Ensure both position and duration parameters are provided.

Privacy & Security

• Your Readwise API token is stored securely on your local machine
• Your Readwise data is only accessed when explicitly requested
• No data is permanently stored on the MCP server
• Safety confirmations prevent accidental data loss
