## Set up Tella in Codex

1. **Add the Tella MCP server.** Codex detects Tella's sign-in and gives you a link to open.

```bash
codex mcp add tella --url https://api.tella.com/mcp
```

2. **Sign in to Tella.** Sign in in your browser and pick a workspace. To sign in again later, run codex mcp login tella. Restart Codex so the Tella tools load.

3. **Add Tella's editing skills (optional).** The skills teach your agent to read a video before editing it, pick the right tool, and check the result. They add workflows like removing mistakes, auto layouts and short clips.

```bash
npx skills add tellahq/skills -g -a codex
```

## Questions people ask

### Can Codex edit videos?

Yes, once you connect Tella. Codex can't edit a video file by itself, but with the Tella MCP server it can cut clips by transcript, remove filler words and silences, add zooms, layouts, captions and B-roll, export, and publish to YouTube, LinkedIn, X, Instagram and Facebook.

### How do I connect Codex to Tella?

Run codex mcp add tella --url https://api.tella.com/mcp in your terminal. Codex detects Tella's OAuth sign-in and opens Tella in your browser. Sign in, then restart Codex so the Tella tools load.

### Do I need an API key?

No. You sign in to Tella in your browser with OAuth and pick a workspace, and the agent never sees your password. Use an API key only for scripts, CI, or a client that can't open a browser.

### Can Codex change videos without asking?

Codex works with your Tella permissions in the workspace you pick, and only edits videos you can edit. Most agents ask before running a tool that changes something, and you can disconnect Tella at any time.

### Is it free?

The Tella MCP server is included on every plan, including the 7-day free trial with no credit card. Pro is $13 a month, billed annually. Auto Capture uses credits for each take.
