This tool generates a complete snapshot of your memory with flexible filtering options.

Usage Example

Export everything:

  "format": "json"
}
Export a specific project: 
{
  "project": "my-app",
  "format": "markdown"
}
Export last 30 days: 
{
  "days": 30,
  "format": "json"
}
Export with full raw data: 
{
  "project": "my-app",
  "include_raw": true,
  "format": "json"
}
Backup recent work on a project: 
{
  "project": "my-app",
  "days": 7,
  "format": "markdown",
  "include_raw": false
}

Tips

  • Large exports: Full exports can be large. Consider filtering by project or days
  • include_raw: Only use include_raw: true when you need complete tool input/output data
  • Markdown for humans: Use markdown format for readable reports and sharing
  • JSON for tools: Use JSON format for programmatic analysis or backup
  • Response truncation: Markdown responses are truncated in MCP responses. The full export is generated but only preview is shown
  • Backup strategy: Export regularly by project to keep manageable snapshots
  • Days parameter: Use days to limit scope — e.g., export last 7 days for weekly reviews
