List running applications and open windows so workflows can discover and target them.

Security

Grants AI assistants full control over the desktop and any application, including the user's logged-in browser session, cookies, and auth. Never hard-code credentials in workflows—use environment variables or a secret manager. Workflows are code: store them in version control and review changes. Run with elevated/administrator privileges only when accessibility features require it.

Terminator MCP Agent + Claude Desktop FAQ

Where is the Claude Desktop config file?

Claude Desktop reads MCP servers from ~/Library/Application Support/Claude/claude_desktop_config.json. Paste the Terminator MCP Agent config there under the "mcpServers" key and restart the client.

Is Terminator MCP Agent safe to use with Claude Desktop?

Which operating systems are supported?

Windows only. The README explicitly states macOS and Linux are not supported.

How do I install it in Claude Code?

Run the one-liner: claude mcp add terminator "npx -y terminator-mcp-agent@latest". For other clients, add the mcpServers block with command "npx" and args ["-y", "terminator-mcp-agent@latest"], or run npx -y terminator-mcp-agent@latest --add-to-app.

Does it take over my mouse and keyboard?

No. It runs in the background using the accessibility tree and your browser session, so it does not hijack your cursor or keyboard or require you to re-login.
