Tabby

Tabby-MCP turns your Tabby Terminal into an extensible MCP server, letting AI assistants control and interact with your terminal. It provides 34 tools for terminal control, tab management, profiles/SSH, and SFTP, all with secure defaults and flexible session targeting so you can automate and stream commands safely from client applications.

How to use

You connect AI clients to Tabby-MCP using either a remote HTTP endpoint or a local STDIO bridge. HTTP gives you a single, streamable interface over a URL, while STDIO lets you run a local bridge that talks to Tabby-MCP from your editor or desktop client. The tools include terminal control, tab management, profile handling, and SFTP operations (with dependencies on the tabby-ssh plugin when SFTP is used). Use the HTTP endpoint when your client supports remote connections, or use STDIO when your client runs on the same machine and can spawn a bridge process.

After installation

1. Restart Tabby. 2. Go to Settings → MCP. 3. Start the MCP server.

Configuration reference

Key settings include the MCP server port, auto-start behavior, pair programming confirmations, session tracking, and SFTP enablement. You can adjust these to tailor how you want the server to operate and how much you want to log or confirm actions.

Endpoints and connection options

You can connect clients via two modes:

• SSE/HTTP: Use a server URL such as the streamable HTTP endpoint or legacy SSE endpoint for remote clients.
• STDIO: Run a local bridge that connects to the SSE server, used by clients like Claude Desktop or IDE integrations that support a local stdio bridge.

Platform support and notes

macOS is tested and fully functional. Windows and Linux are untested in official tests, but the setup should work. Community feedback is welcome to help verify cross-platform compatibility.

Security and reliability

The server includes a pair programming mode with confirmation dialogs, comprehensive logging, and safe command execution to reduce unintended actions and improve traceability.

End-to-end connection details

The primary endpoints used for connections are:

• Streamable HTTP: http://localhost:3001/mcp
• Legacy SSE: http://localhost:3001/sse
• Health: http://localhost:3001/health
• Info: http://localhost:3001/info These endpoints enable clients to stream commands, monitor status, and verify the server health.

SFTP considerations

SFTP operations are available when the tabby-ssh plugin is installed. If SFTP is enabled, you can list, read, write, create directories, delete, rename, and transfer files with both synchronous and asynchronous options. SFTP size limits are configurable in settings.

Tools at a glance

Tabby-MCP provides a comprehensive set of 34 tools across four categories: Terminal Control, Tab Management, Profile Management, and SFTP Operations. These tools enable you to list sessions and tabs, execute commands, manage inputs, read buffers, split and manage tabs, profile operations, and remote file actions.

Troubleshooting tips

If you encounter issues with connections, confirm that the MCP server is running on the expected port (default 3001). Check logs for transport or session errors, and ensure the proper bridge or HTTP URL is used for your client. When using STDIO, verify the bridge script path and Node.js installation. For SFTP, ensure the tabby-ssh plugin is installed and active.

Examples and best practices

Use stable session IDs for reliable cross-tab and cross-session tracking. When using STDIO, prefer explicit bridge configurations over relying on defaults to ensure your client connects to the correct local bridge. Enable pair programming with confirmations for actions that could affect the terminal state.
