CLI agent
Antigravity CLI
Google's terminal agent for the Antigravity platform, run with the agy command. It understands your codebase, makes edits with your permission and runs commands. It is the home for the Google account access that used to go through Gemini CLI.
Free tier MCP support
Pricing
Google's Antigravity pricing page lists an Individuals plan at $0 a month, with basic weekly rate limits, plus Google AI Pro and Google AI Ultra plans with larger limits. Google's docs don't give numeric quotas, and Pro and Ultra prices aren't shown on that page. Business use through Google Cloud is priced separately. Check antigravity.google/pricing before you rely on any limit.
