Set up with Google Antigravity

Create a service key

Sign in to your mob.so account. Under Service keys, select Create key, name it Antigravity, and copy the key. mob.so shows the key once.Antigravity uses this key to act as your user account with that account’s permissions.

Add mob.so

In Antigravity IDE, open the … menu at the top of the agent side panel. Select MCP Servers, then Manage MCP Servers > View raw config.Add this configuration to mcp_config.json, replacing YOUR_SERVICE_KEY with the key you copied:

{
  "mcpServers": {
    "mob": {
      "serverUrl": "https://mob.so/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_SERVICE_KEY"
      }
    }
  }
}

Merge the mob entry into mcpServers if you already have other servers configured. Save the file and refresh the server list. Keep this file private because it contains your service key.

Verify the connection

Enable mob and check that its tools appear. Start an agent conversation and enter:

Verify access

Use mob.so to show my connected account and list the mobs I can access.

Check that Antigravity returns your mob.so account and its available mobs.

See the Google Antigravity MCP documentation for current client configuration.
