Gemini and Antigravity
Antigravity CLI is Google's agent client; Gemini is the model it runs. The Individual plan has a free starter quota, so connecting Wikilayer does not require a paid plan.
Install and sign in
Install the current CLI with Google's official installer:
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
Open Antigravity's global MCP configuration in a regular terminal:
mkdir -p ~/.gemini/config
nano ~/.gemini/config/mcp_config.json
For a new file, use:
{
"mcpServers": {
"wikilayer": {
"serverUrl": "https://wikilayer.org/mcp"
}
}
}
If the file already contains MCP servers, add the wikilayer entry inside its existing mcpServers object instead of replacing the file. Restart agy after saving.
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.

Try a first question to confirm that Antigravity can see your wikis.
