Google Antigravity

Google Antigravity connects to the Equibles MCP server through its built-in MCP settings. You do not need to write a program or install a local server.

1. Open the MCP configuration

In Antigravity IDE:

1. Click … at the top of the agent side panel.
2. Select MCP Servers.
3. Click Manage MCP Servers → View raw config.

This opens Antigravity's shared mcp_config.json file. The same server will be available in Antigravity, Antigravity IDE, and Antigravity CLI.

2. Add the Equibles server

Paste this into the file and save it:

{
  "mcpServers": {
    "equibles": {
      "serverUrl": "https://mcp.equibles.com/mcp"
    }
  }
}

Already have other servers in mcpServers? Add only the "equibles": { ... } entry beside them instead of replacing the whole file. Antigravity requires serverUrl for a remote server; url and httpUrl do not work here.

Return to Settings → Customizations → Installed MCP Servers and click Refresh. When Equibles appears, click Authenticate, sign in to Equibles in your browser, copy the authorization code, and paste it back into Antigravity.

Prefer an API key? Create one at /dashboard/apikeys (it starts with eq_ and is shown once), then use:

{
  "mcpServers": {
    "equibles": {
      "serverUrl": "https://mcp.equibles.com/mcp",
      "headers": {
        "Authorization": "Bearer eq_your_api_key"
      }
    }
  }
}

Treat this file as a secret when it contains an API key. See Google's MCP guide for Antigravity's current configuration screens and file locations.

3. Test it

Start a conversation or agent task and ask one of these. Name Equibles in the prompt so Antigravity calls the connected tools instead of answering from memory or searching the web:

Antigravity asks before using newly connected MCP tools by default. Approve the Equibles call when prompted; you can change that permission later if you want an agent to run without asking each time.
