This is the canonical first-run debugger workflow for pwno-mcp.
1

Create a named debug session

{"tool":"create_debug_session","arguments":{"session_id":"chal-a"}}
2

Load the target binary

{"tool":"set_file","arguments":{"binary_path":"/workspace/chal","session_id":"chal-a"}}
3

Set a breakpoint at main

{"tool":"set_breakpoint","arguments":{"location":"main","session_id":"chal-a"}}
4

Run the program

{"tool":"run","arguments":{"args":"","start":false,"session_id":"chal-a"}}
5

Inspect the current state

{"tool":"get_context","arguments":{"context_type":"all","session_id":"chal-a"}}
{"tool":"get_memory","arguments":{"address":"$rsp","size":64,"format":"hex","session_id":"chal-a"}}
6

Step once

{"tool":"step_control","arguments":{"command":"n","session_id":"chal-a"}}
At this point you should have a stable named session you can continue using for more breakpoints, raw execute commands, or an interactive pwncli flow.

​
Useful follow-ups

  • use finish to run out of the current function
  • use until to run until a location or next source line
  • use gdb_interrupt if the inferior is still running and you need to regain control
