Antigravity Terminal

Windows-focused MCP server for terminal automation with persistent sessions and live session logs. Created by AATHI.

Features

• Persistent PowerShell sessions (session_id, default: default)
• Incremental stdout/stderr polling
• Send follow-up input into running sessions
• Live log file path returned for each session
• Configurable monitor mode via ANTIGRAVITY_MONITOR_MODE
• VS Code integrated terminal metadata returned for each session
• MCP standard methods (tools/list, tools/call) with legacy aliases

MCP Tools

1. run_command
2. command_status
3. send_input
4. list_sessions
5. session_visual_info
6. kill_command

Publish-Ready One-Command Usage (From GitHub)

After pushing this project to your GitHub, users can seamlessly install and attach it to Claude using uvx (or the more robust python -m uv variant for Windows):

# Standard uvx (if in PATH)
claude mcp add antigravity-terminal-mcp uvx --from git+https://github.com/aathishwar-13/antigravity-terminal-mcp.git antigravity-terminal-mcp

# More robust Windows version (if uvx is not in PATH)
claude mcp add antigravity-terminal-mcp python -m uv tool run --from git+https://github.com/aathishwar-13/antigravity-terminal-mcp.git antigravity-terminal-mcp

(Note: If the code is nested in a subdirectory, simply append #subdirectory=folder_name to the git URL).

Local Run

uvx --from . antigravity-terminal-mcp

or

python server.py

Monitor Modes

By default, the server does not open an external monitor window (ANTIGRAVITY_MONITOR_MODE=none). This keeps monitoring in VS Code when you use the integrated terminal bridge.

If you explicitly want a separate PowerShell window for each session monitor, enable external mode:

$env:ANTIGRAVITY_MONITOR_MODE = "external"
python server.py

To force no external monitor window:

$env:ANTIGRAVITY_MONITOR_MODE = "none"
python server.py

When run_command or session_visual_info is called, the response now includes:

• log_path
• watch_command
• monitor_mode
• vscode_terminal
• monitor_open (quick-open metadata for clickable/open actions)

monitor_open includes:

• command_uri (VS Code command URI for antigravityTerminal.openMonitor)
• markdown_link (prebuilt markdown clickable link for chat UIs)
• integrated_terminal_command (copy/paste command to open live monitor in integrated terminal)
• open_terminal_uri (opens a VS Code integrated terminal)
• open_terminal_with_cwd_uri (opens integrated terminal in session cwd)
• run_in_active_terminal_uri (runs monitor command in active integrated terminal)

The vscode_terminal object is designed for a VS Code extension to open the same session monitor inside an integrated terminal.

VS Code Integrated Terminal Bridge

A lightweight extension scaffold lives in vscode-integration/.

What it does

• Opens an integrated PowerShell terminal in the current VS Code window
• Runs the returned watch_command / vscode_terminal.command
• Lets you paste either the full session_visual_info JSON or just the log_path
• Shows a status-bar button: MCP Monitor (bottom-right) to pick and open any existing session monitor
• Auto-detects session_logs/*.log create/change activity and shows an Open Monitor popup action

How to try it locally

1. Open antigravity_mcp/vscode-integration in VS Code.
2. Press F5 to launch the extension host.
3. Run Antigravity: Open Monitor From Session Info JSON from the Command Palette.
4. Paste the JSON returned by session_visual_info or run_command.

Where to click

• Bottom-right VS Code status bar: click MCP Monitor and choose a session
• On new session creation: click Open Monitor in the popup notification

This uses the VS Code extension API, which is the correct way to open an integrated terminal in the current editor window. A plain Python process cannot directly create a terminal tab inside VS Code by itself.

Quick Integrated Monitor Command (No Copy/Paste)

Use the helper script from a VS Code integrated terminal:

Set-Location d:\Projects\Client_projects\Velyx_Chatbot\antigravity_mcp
.\open-monitor.ps1 -SessionId live-agent

Optional short alias for the current terminal session:

Set-Alias agmwatch .\open-monitor.ps1
agmwatch -SessionId live-agent

This keeps monitoring inside VS Code and does not open an external terminal window.

Example MCP Config

{
  "mcpServers": {
    "antigravity-terminal-mcp": {
      "command": "python",
      "args": [
        "-m",
        "uv",
        "tool",
        "run",
        "--from",

        "antigravity-terminal-mcp"
      ]
    }
  }
}

Or
