runProcess tool
The runProcess tool runs processes on the host machine. There are two mutually exclusive ways to invoke it:
command_line(string) — Executed via the system's default shell (just like typing intobash/fish/pwsh/etc). Shell features like pipes, redirects, and variable expansion all work.argv(string array) — Direct executable invocation.argv[0]is the executable, the rest are arguments. No shell interpretation.
You cannot pass both. The tool infers whether to use a shell from which parameter you provide.
If you want your model to use specific shell(s) on a system, I would list them in your system prompt. Or, maybe in your tool instructions, though models tend to pay better attention to examples in a system prompt.
Let me know if you encounter problems!
Tools
Tools are for LLMs to request. Claude Sonnet 3.5 intelligently uses run_process. And, initial testing shows promising results with Groq Desktop with MCP and llama4 models.
Currently, just one command to rule them all!
run_process- run a command, i.e.hostnameorls -alorecho "hello world"etc- Returns
STDOUTandSTDERRas text - Optional
stdinparameter means your LLM can- pass scripts over
STDINto commands likefish,bash,zsh,python - create files with
cat >> foo/bar.txtfrom the text instdin
- pass scripts over
- Returns
