cmux-cua

# cmux-cua cmux bundles a local computer-use engine (packaged as `cmux Computer Use` with the MCP proxy named `cmux-cua`, from a pinned build of the `manaflow-ai/cmux-cua` fork) and attaches it as an MCP tool server named `cmux-cua` to every agent session cmux launches (Claude Code, Codex). The agent can then perceive and operate real macOS apps: read the accessibility tree, take screenshots, and click / type / scroll / drag. Everything runs locally through the bundled **cmux Computer Use** helper. The helper has its own TCC identity, so Accessibility and Screen Recording never belong to the main cmux app and granting Screen Recording never requires restarting cmux. Upstream telemetry and update checks are disabled at runtime. Do not invoke this skill, start its helper, request permissions, or perform a GUI action when the user is only reading, asking about, quoting, or mentioning Computer Use. Wait for a direct user request to use Computer Use; missing tools or permissions are not a reason to begin setup automatically. ## How it attaches - The `cmux-claude-wrapper` and `cmux-codex-wrapper` inject `cmux-cua` as an MCP proxy using `mcp --socket <cmux-owned socket>` plus cursor-branding and state-dir env. Codex launches the exact tag-installed helper executable as its authenticated approval broker; Claude uses the bundled native-profile proxy client. The Codex wrapper additionally passes `--codex-computer-use-compat`; the Claude wrapper deliberately does not. A...
