Connect ChatCut Desktop

Use the signed production Desktop app as the only source of the local MCP server and editing skills. This plugin contains instructions only, not an installer or MCP configuration.

If chatcut_desktop tools are already available, call get_active_project and continue with the user's editing request. Do not reinstall the app or change MCP configuration. If the current host is ChatCut Desktop's managed Codex agent, stop; its project-pinned MCP and built-in skills are already authoritative.

Download

Use only the matching official URL:

• macOS Apple Silicon: https://api.chatcut.io/desktop/download/macos
• macOS Intel: https://api.chatcut.io/desktop/download/macos-x64
• Windows x64: https://api.chatcut.io/desktop/download/windows

ChatCut Desktop supports macOS 13 or newer on Apple Silicon or Intel and Windows on x64. Linux is unsupported. Do not substitute a search result, third-party mirror, hosted ChatCut MCP, or historical chatcut@chatcut-inc plugin.

Install or repair

Try to complete the ordinary platform installation for the user with the host's narrow command approval:

1. Detect the operating system and architecture and choose the URL above.
2. Download the official artifact to a temporary directory. If ChatCut is already installed but will not open, inspect it before replacing it.
3. On macOS, use native tools to mount a DMG or extract a ZIP, then copy ChatCut.app to /Applications or the user's Applications directory. On Windows, open the downloaded installer and let the visible installer finish.
4. Open ChatCut Desktop. It registers chatcut_desktop and synchronizes its editing skills into Codex automatically.

Installing outside the project sandbox or opening an installer may require host approval. Request only the scoped operation needed for that step; never ask the user to enable persistent Full access.

For macOS launch or code-signing failures, inspect codesign, Gatekeeper, permissions, and quarantine state. Try remounting or re-extracting a fresh official download, fixing destination permissions, or clearing stale quarantine only after the official app's signature validates. Never modify or ad-hoc sign the app, disable Gatekeeper, or bypass an invalid signature. On Windows, do not bypass an invalid or unknown Authenticode publisher warning.

Retry one fresh official download if the artifact is incomplete, corrupt, for the wrong architecture, or fails a normal copy or extraction step. Do not loop.

User handoff

If the host cannot download, mount, extract, copy, approve, repair, or run the installer, stop trying. Tell the user what blocked automation and give them the exact matching official URL above so they can install and open ChatCut with the visible operating-system flow.

After ChatCut opens, ask the user to sign in there if needed. Do not handle their credentials or add chatcut_desktop to config.toml manually. Because Codex loads MCP tools and skills when a task starts, tell the user to start a new task after Desktop finishes connecting.
