## What is KDB?
KDB is a **time-travel debugger** that connects to Claude, Cursor, or any MCP-compatible AI assistant. Instead of reading code and guessing, your AI can now:
- **Attach** to running processes
- **Set breakpoints** and catch crashes in action
- **Step forward** through execution
- **Step BACKWARD** through time to find the root cause
- **Inspect memory** and variables at any point in history
All through natural language. Just ask Claude to debug your code.
