macOS Harness

Thin Python harness that gives an LLM agent direct control of a Mac through raw primitives.

Pluginfree

macOS Harness is a thin Python library that gives an LLM agent direct control of a Mac through six raw primitives — see, key, type, click, accessibility access, and scripting — instead of a fixed set of app-specific tools. The agent writes the specific actions it needs mid-task using real browser, filesystem, and subprocess access in the same process. It's built for developers building AI agents that need general-purpose Mac control rather than a pre-built tool library.
