How It Works

This MCP server uses the unofficial Otter.ai API to:

1. Authenticate with your Otter.ai credentials

2. Use the advanced_search endpoint for full-text search across all transcripts

3. Retrieve full transcript content with speaker diarization

The advanced_search API searches the actual transcript content, not just titles and summaries, making it much more useful for finding specific conversations.

Security Notes

• Credentials are passed via environment variables, not stored in code

• Uses HTTPS for all API communication

• Session tokens are managed in memory only
