Neonix MCP for Antigravity

Connect Google Antigravity to Neonix for editable motion video projects. Antigravity's CLI and IDE share one MCP configuration, so this setup works in both.

Connection details

Field	Value
MCP endpoint	`https://www.neonix.video/api/mcp`
Auth	OAuth 2.1 — no API key or client ID needed
Config file	`~/.gemini/config/mcp_config.json`

Setup flow

Open the MCP config — In Antigravity, go to Settings > Customizations and click Open MCP Config, or open Manage MCP Servers > View raw config. Either one edits ~/.gemini/config/mcp_config.json directly.

Add the server — Antigravity uses serverUrl for a remote server, not url:

{
  "mcpServers": {
    "neonix": {
      "serverUrl": "https://www.neonix.video/api/mcp"
    }
  }
}

Refresh and authorize — Save the file, then refresh the Installed MCP Servers list. Antigravity opens the browser for OAuth sign-in the first time it calls a Neonix tool — no client ID or secret needed. Approve workspace access.
Create motion — Ask Antigravity to create or update an editable project.
