Antigravity CLI Companion downloads statistics

Runs the Antigravity CLI (agy) in a JetBrains IDE terminal (PhpStorm, IntelliJ IDEA, WebStorm, PyCharm, GoLand, etc.) and feeds it live editor context over MCP — active file, selection, open tabs, and inspection diagnostics, on demand.

Independent third-party plugin — not Google's official Antigravity extension. Google's own agent installs from JetBrains AI → Settings → Agents and requires IDE 2026.2.1+ — see Google's official setup guide. If you want that first-party agent panel, use it. This plugin has a different purpose: it runs the Antigravity CLI (agy) in an IDE terminal and feeds it editor context over MCP, on IDE 2023.2 and up, with no JetBrains AI dependency.

The plugin runs a small local MCP (Model Context Protocol) server inside the IDE and registers itself in ~/.gemini/config/mcp_config.json. Whenever agy needs editor context it calls the plugin over MCP — no env vars, no lockfiles, no platform-specific bridges.

Click the Open Antigravity CLI toolbar button (top-right) to launch agy in an IDE-embedded terminal pre-wired to the running project. By default the button focuses the existing Antigravity terminal tab if one is open; enable Always open a new tab in settings to spawn a fresh session on every click.

Exposed MCP tools

• ide_get_active_editor — current file path, language, cursor, selection, content. • ide_get_open_files — every file currently open in an editor tab. • ide_get_diagnostics — inspections/errors/warnings for a file. • ide_open_file — open a file at an optional line/column.

Artifacts tool window

A right-anchored tool window lists recent brain entries agy generates — plans, summaries, walkthroughs from your conversations. Sorted by most-recently modified so the active session's output is always at the top; the conversation ID prefix on each row helps distinguish entries that share a filename. Auto-refreshes every few seconds while the tab is open; double-click any entry to open it in the editor.

Configure the path to your agy binary under Settings → Tools → Antigravity CLI Companion. No keyboard shortcut is bound by default — assign one via Settings → Keymap (search Open Antigravity CLI) or from the link in the plugin's settings panel.
