Neonix MCP for Codex

Connect Codex to Neonix for editable motion video projects. Use the hosted MCP server to create, update, preview, and export editable motion projects from a Codex session.

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	`~/.codex/config.toml` (or `.codex/config.toml` for a trusted project)

Setup flow

Add the server — Run:
```
codex mcp add neonix --url https://www.neonix.video/api/mcp
```
Codex writes a matching [mcp_servers.neonix] table to config.toml. Skip --bearer-token-env-var — Neonix authenticates over OAuth, not a static token.
Authorize — Start a Codex session; Codex opens the browser for OAuth sign-in the first time it calls a Neonix tool. Approve workspace access.
Verify — Inside a session, run /mcp to confirm Neonix is connected and see its tools.
Create motion — Ask Codex to create or update an editable project.
