# Connect Codex

Configure Codex to use MARqentic’s remote marketing research tools.

## Set up the connection

Use this deployment’s remote MCP endpoint. Cloud-hosted clients need a publicly reachable HTTPS address; a localhost preview is only reachable by clients running on your machine.

1. Run the add command, then the login command below.
2. Complete the browser sign-in and review the requested workspace access.
3. Start or refresh your Codex session so it discovers the server’s tools.
4. Ask for a free estimate before approving paid research.

```
codex mcp add marqentic --url https://devshine-seo-mcp.vercel.app/mcp
codex mcp login marqentic
```

## Check the connection

Ask the assistant to list its MARqentic tools, then estimate a small research request with dry_run: true where supported. The result should include cost metadata. Paid execution needs sufficient credits in the approved workspace.

Missing tools may mean a category is disabled or the client has an older cached tool list. Refresh discovery before reconnecting.
