Processes - pwno-mcp

These tools are for helper services, build steps, and supporting automation. They are not for running the target binary under debugger control.

run_command and spawn_process intentionally guard against some bad patterns, including using them to run a target ELF from /workspace or wrapping python -c instead of using the Python tool family.

Returned shape

All tools on this page return JSON-formatted strings. Parse the payload if your client does not already coerce it into an object.

`run_command`

Use for short-lived shell commands such as compiles and helper scripts.

{"tool":"run_command","arguments":{"command":"gcc -g vuln.c -o chal","cwd":"/workspace","timeout":30.0}}

Background helpers

Tool	Use it for	Important fields
`spawn_process`	start a long-running helper process	`pid`, `stdout_path`, `stderr_path`, `process_dir`
`get_process`	inspect one tracked background process	running status plus live or final output
`kill_process`	stop a tracked process	signal defaults to `15`
`list_processes`	inspect all tracked helpers	lightweight running-process summary

{"tool":"spawn_process","arguments":{"command":"python3 -m http.server 8000","cwd":"/workspace"}}
{"tool":"get_process","arguments":{"pid":12345}}
{"tool":"kill_process","arguments":{"pid":12345,"signal":15}}
{"tool":"list_processes","arguments":{}}

What gets tracked

stdout and stderr are written to log files under a server-managed process directory
get_process returns live output for tracked running processes when available
kill_process keeps the entry cached long enough for get_process to read outputs afterward

Use Build and Helper Processes for workflow guidance.
