Unreal Engine MCP Server

# src/automation WebSocket bridge client and protocol handling. ## OVERVIEW Manages connection to Unreal Engine and provides a promise-based API for requests. ## WHERE TO LOOK | Task | File | Notes | |------|------|-------| | Bridge Client | `bridge.ts` | Main AutomationBridge class | | Connection | `connection-manager.ts` | Reconnect logic, heartbeat | | Handshake | `handshake.ts` | Protocol version negotiation | | Protocol Logic | `message-handler.ts` | JSON-RPC frame processing | ## CONVENTIONS - **Request Tracking**: Every request must have a unique ID tracked in `request-tracker.ts`. - **Handshake Protocol**: Must negotiate capabilities before sending commands. - **Byte Checks**: WebSocket size limits must be checked in **BYTES**, not string length. - **Retry Strategy**: Exponential backoff for connection failures. ## ANTI-PATTERNS - **Raw WS Send**: Never use `ws.send()` directly; use the bridge's send queue. - **Unhandled Timeouts**: Every request must have a configurable timeout. - **Logging Secret Tokens**: Never log the `MCP_AUTOMATION_CAPABILITY_TOKEN`.
