# Connect Codex

> Install the Superdata Codex plugin and authenticate with browser sign-in.

Use these steps with the Codex desktop app or Codex CLI.

<Steps>
  <Step title="Install the plugin">
    Run this command on the same computer where you use Codex:

    ```bash theme={null}
    codex plugin marketplace add superdata-hq/superdata-plugins --ref main \
      && codex plugin add superdata@superdata \
      && codex mcp login superdata
    ```
  </Step>

  <Step title="Sign in to Superdata">
    When the browser opens, sign in with your approved Superdata account and
    approve the connection.
  </Step>

  <Step title="Restart Codex">
    Fully quit and reopen the desktop app, or start a new CLI session.
  </Step>

  <Step title="Verify Superdata">
    Select Superdata from the plugin picker or ask Codex to use Superdata for a
    focused company search.
  </Step>
</Steps>

<Note>
  This command installs the Superdata plugin package, enables the bundled
  Superdata skill, connects the hosted MCP server, and starts OAuth sign-in.
  API keys remain available for CI and other non-interactive clients.
