About Antigravity CLI
Antigravity CLI is Google's agent client for the terminal; it runs Gemini and other models, Claude among them. Its free Individual plan has weekly limits, so connecting Wikilayer needs no paid plan.
Install and sign in
On macOS or Linux, install the current CLI with Google's official installer; Windows has its own command there:
curl -fsSL https://antigravity.google/cli/install.sh | bash
Start it:
agy
Antigravity opens a browser. Sign in with your Google account, then return to the terminal.
Add Wikilayer
Add Wikilayer from the terminal:
agy mcp add wikilayer https://wikilayer.org/mcp
agy mcp list then shows it as enabled. The command writes Antigravity's global configuration, ~/.gemini/config/mcp_config.json, and keeps any servers already there. Restart agy if it was running.
Authorize access
Inside Antigravity, open the MCP manager:
/mcp
Select wikilayer, then Authenticate. Open the URL it gives you, sign in to Wikilayer, and approve access. Copy the authorization code from the browser and paste it back into Antigravity. The server status changes from Auth Needed to authenticated. Google's MCP guide describes the same sign-in.
What's next
Once Antigravity can reach Wikilayer, try the first steps.
