OpenAI Codex is a coding agent, not a LinkedIn client. If you already run it against the repo, the same session can talk to  [Omentir](https://omentir.com/index.md)  over MCP, score a batch, and leave drafts. It should not hold a LinkedIn password. It should not invent a campaign while you are midway through a refactor.

This is not the ChatGPT connector. ChatGPT uses Settings, Connectors, and workspace approval. Codex reads  ~/.codex/config.toml. Mixing those paths is how people paste a token into a chat UI, or wait for an OAuth screen that never appears.

## Why the TOML file matters

The CLI and the IDE extension share the same file. Get the table name wrong (mcp-servers instead of mcp_servers) and Codex ignores the block. If you paste the actual token into bearer_token_env_var, Codex treats that string as a variable name and auth fails. Put OMENTIR_API_KEY there, and export the key before you launch. Then run /mcp in the session. If the server is missing, fix that before you invent a second connect path.

A project-local `.codex/config.toml` only loads for trusted projects. If tools never appear, start with the global file. Setup:  [Codex integration](https://omentir.com/integrations/codex.md) .

## The config Codex expects

Create a revocable key. Export it as OMENTIR_API_KEY. Point url at  CODEX_MCP_URL. Keep send behind review.

## A first Codex job

Finish Omentir first. Fetch  [agents.md](https://omentir.com/agents.md) . Start with get_context and list_agents. If you want a new finder, ask it to show the config and wait. Replace the brackets. Keep the last two sentences.

## Not ChatGPT chat

If you wanted a conversation this afternoon with no repo open, use the  [ChatGPT integration](https://omentir.com/integrations/chatgpt.md) . If you wanted the editor instead of Codex, use  [Cursor for LinkedIn outreach](https://omentir.com/blogs/cursor-linkedin-outreach.md) . Overnight research is  [Grok Bot](https://omentir.com/blogs/grok-bot-linkedin-sales.md) .

## When to stay in the browser

You are not in Codex. The product story is still a slogan. You cannot give the list fifteen minutes. Start in Overview. Codex earns the key when that agent is already in the repo.

## FAQs

## Frequently asked questions

**Is Codex the same as ChatGPT for outbound?**

No. ChatGPT chat uses Connectors and workspace approval. Codex uses config.toml and a Bearer env var. Same Omentir tools. Different machine.

**Where does the MCP config live?**

Usually ~/.codex/config.toml. A project .codex/config.toml only loads for trusted projects. The table name is mcp_servers, with an underscore.

**Can I put the API key in the TOML file?**

bearer_token_env_var wants the variable name, not the token. Pasting the key into the file is how it lands in git.

**Does Codex keep working after I close it?**

No. Overnight on a shared computer is Grok Bot, a different product.

**Should I use Cursor instead?**

Use Cursor if that is already the editor. Use Codex if you already run the Codex CLI or extension. Do not run both on day one.

**Do I need Codex if I already use Omentir?**

No. Overview already finds people and drafts notes. Add Codex if that agent is already in the repo.

## Paste-ready job

```
You are Codex, running against my repo through Omentir.

My product helps [buyer] get [result]. Best-fit accounts are [company type, size, region]. Strong signals: [signal]. Skip [bad fit].

Work only through the Omentir MCP server named in config.toml. Read https://omentir.com/agents.md if you have not. Start with get_context, then list_agents. If no finder matches this ICP, show me a create_agent config and wait for a yes.

Do not put secrets in config.toml. bearer_token_env_var is the name of an environment variable, not the token.

Pull up to 30 people. For each one write fit 1-5, the evidence, any risk, and a two-sentence draft that cites a real trigger. If a note could fit two buyers, rewrite it.

Do not send. Do not enroll. Do not sign into LinkedIn.
Do not create, delete, or reply unless I ask in this session.
