Codex

You need an API key from the dashboard (igk_live_..., shown once).

1. Put the key in your environment

export VINCEVANGEN_API_KEY="igk_live_..."

2. Add the server to ~/.codex/config.toml

[mcp_servers.vvgen]
url = "https://api.vincevangen.com/mcp"
bearer_token_env_var = "VINCEVANGEN_API_KEY"
tool_timeout_sec = 600

bearer_token_env_var names the variable; Codex sends Authorization: Bearer <value>. The key is never written to the file. The longer timeout covers video and music, which run as jobs you poll with vvgen_get_job.

3. Use it

Start codex and ask:

Create a 16:9 header photo for a blog post called "Shipping faster": a sunlit workbench, the top third empty. Add the title as an overlay.

The agent generates the art without words, then adds the exact title with text_overlay, which is free and spelled exactly.

Troubleshooting

Symptom	Cause
Server not listed	Codex reads the file at startup; restart it.
401	The variable is unset in the shell that launched Codex.
Long jobs time out	Raise tool_timeout_sec, or poll the job id instead of waiting.
