Implements LangGraph's agentic loop with interrupt-based tool approval, allowing users to inspect, deny, or modify tool parameters before execution. Supports both stdio and HTTP MCP transports with automatic reconnection and tool name collision prevention. Leverages PostgreSQL checkpoints to resume multi-turn conversations across sessions, with file uploads streamed to S3-compatible storage and real-time SSE responses powered by React Query client-side state management.
