2Code Import System for Visual Workflow Builder 

3 

4Enables round-trip capability: Python ↔ Visual 

5 

6Features: 

7- Parse Python LangGraph code 

8- Extract workflow structure (nodes, edges, state) 

9- Auto-layout for visual canvas 

10- Type inference for node configurations 

11 

12This completes the round-trip: 

13- Visual → Code (export) ✅ 

14- Code → Visual (import) ✅ 

15 

16Example: 

17 from mcp_server_langgraph.builder.importer import import_from_file 

18 

19 # Import existing Python agent 

20 workflow = import_from_file("src/agents/my_agent.py") 

21 

22 # Now edit visually in builder 

23 # workflow contains nodes, edges, positions for canvas
