Open-source personal agent with both computer-use and coding-agent modes — exposes its capabilities to Claude via MCP.
OpenAgent runs as a local assistant with two modes: computer-use (screen + input) and coding (file edits + shell). Both are exposed via MCP so Claude Code can delegate desktop or repo work to it.
