Use Mode Agent with Codex.
Keep Codex on the build. Mode Agent brings customers to what you ship, every day. Add Mode as a remote MCP server and Codex can start growth work and check on Mode Agent without leaving your terminal.
Way one
Side by side.
Run Codex in one pane and Mode Agent in the next. Codex writes the code. Mode Agent handles the growth and marketing around it.

Way two
Connect Codex to Mode with MCP.
Add Mode to Codex as a remote MCP server. Codex can then start growth work, check on Mode Agent, and set up recurring runs while it builds.
- Add the server.bash
codex mcp add mode --url https://app.gotmode.tech/mcp - Sign in. Your browser opens, you sign in with your Mode account, and you approve access.bash
codex mcp login mode - Start Codex and ask it to use Mode.
Prefer editing config? Add this to ~/.codex/config.toml, then run the login command above.
[mcp_servers.mode] url = "https://app.gotmode.tech/mcp"
The Codex CLI and the Codex IDE extension read the same config file, so one setup covers both.

Start work

Set up a recurring run
Turn a request into a schedule, like a report every Monday morning, and deploy it.

FAQ
Common questions
Do I have to stop using Codex?
No. Keep Codex for everything you use it for today. Mode Agent works beside it and takes the daily growth and marketing work off your plate. Connecting the two is optional.
Can Codex spend money through Mode?
No. Connecting Codex lets it start work and check on Mode Agent. Anything that spends money, like an ad budget, still waits for your approval in Mode, and it never counts against your plan.
Do I need an API key?
No. Codex signs in to Mode in your browser with your Mode account, and you approve access there. There is no key to copy or paste.
How do I disconnect Codex from Mode?
Remove the Mode server from Codex and it can no longer call Mode. Mode Agent keeps running your growth and marketing just as before.
