Do I need to install a plugin?

No. Adding the server and signing in is all it takes. Cospark gives Codex its guidance directly when it connects.

Do I need an API key?

No. You sign in with your Cospark account in the browser, once. Videos use the credits on your Cospark plan.

Why the 900-second timeout?

Making a video can take a few minutes. A long timeout gives Codex enough time to wait for the result instead of stopping too soon.

Can Codex use files on my computer?

Yes. Codex can upload your images, videos, and audio (up to 100 MB each) and use them in your ads.

Cospark for Codex

Make video ads with Codex.

Connect Cospark to Codex and hand it the whole job: research, scripts, video, and voiceover. It's built for long, hands-off work like making a dozen ad variations.

Get a Cospark account Setup steps

Making ads well takes more than one tool call. You have to pick the right AI model for each shot, wait for videos to finish, check the results, and fix what's off.

Cospark teaches Codex how to do all of that. As soon as it connects, Codex gets Cospark's guidance on research, models, and prompts, so it works like someone who has made ads before.

Codex is also happy to run for a long time without you. Ask for a batch of variations, go do something else, and come back to finished ads.

Connect in two steps

Add the server, then sign in.

01
Add Cospark to your config
Paste this into your Codex config file. The long timeout gives videos time to finish.
~/.codex/config.toml
```
[mcp_servers.cospark]
url = "https://api.cospark.so/mcp"
auth = "oauth"
tool_timeout_sec = 900
```
02
Sign in
Run this and sign in with your Cospark account in the browser. Then start a new Codex thread.
terminal
```
codex mcp login cospark
```

Great for big batches

Work you wouldn't want to babysit.

Lots of variations at once

One script, five different hooks, five finished ads. Codex makes them all and tells you when the set is ready.

Footage you already have

Point Codex at your raw clips. It watches them, reads what's said, and tells you where every scene changes.

The right voice for the script

Codex picks a voiceover that fits the tone of your script instead of grabbing the first one on the list.

Good to know

How updates and long videos work.

Always up to date

New Cospark features and guidance show up automatically. There's nothing to update on your side.

Keep the long timeout

Some videos take several minutes. The 900-second timeout makes sure Codex waits for them instead of giving up early.
