macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

Then restart Claude Desktop.
Available Tools

Usage Examples
Once configured, use natural language in Claude:
- "Search for meetings about quarterly planning"
- "Get the content from yesterday's standup"
- "List all my workspaces"
- "Show me meetings in the Sales folder"
How It Works
Authentication
The server reads your existing Granola credentials from:
~/Library/Application Support/Granola/supabase.json
No additional login required - it uses your existing Granola session.
API Integration
- Direct REST API calls to Granola's backend
- ProseMirror content converted to readable Markdown
- In-memory caching with 5-minute TTL
Troubleshooting
"Failed to get access token"
Ensure Granola is installed and you're logged in. The server needs:
~/Library/Application Support/Granola/supabase.json
Server not appearing in Claude
- Verify the config path is correct
- Run
npm run build - Restart Claude Desktop completely
