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 + Windsurf FAQ

Where is the Windsurf config file?

Windsurf reads MCP servers from ~/.codeium/windsurf/mcp_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 Windsurf?

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.

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.
