Use the pwncli family when you want an interactive exploit driver that stays attached to a specific debug session.

​
Start a driver

pwncli writes the provided script into the session runtime directory, launches it with uv run, and exposes both startup output and any parsed attach result marker. 
{"tool":"pwncli","arguments":{"session_id":"chal-a","binary_path":"/workspace/chal","file":"from pwn import *\nprint('ready')\n"}}

​
Interact with the driver

  • sendinput writes raw input to the session driver.
  • checkoutput returns buffered output and clears that buffer.
  • checkevents returns structured events and driver liveness data.
sendinput does not append a newline automatically. 
{"tool":"sendinput","arguments":{"session_id":"chal-a","data":"AAAA\n"}}
{"tool":"checkoutput","arguments":{"session_id":"chal-a"}}
{"tool":"checkevents","arguments":{"session_id":"chal-a"}}

​
Stop or inspect sessions

  • pwncli_stop kills the driver bound to a session.
  • list_pwncli_sessions lists all active driver sessions.
{"tool":"pwncli_stop","arguments":{"session_id":"chal-a"}}
{"tool":"list_pwncli_sessions","arguments":{}}
