# ChatGPT

> Connect ChatGPT (on web or desktop) or Codex to the Standard Metrics MCP server

# Set up the Standard Metrics MCP in ChatGPT and Codex

## Prerequisites

* **Plan**: Business or Enterprise.
* **Admin setup**: A workspace admin or owner must enable developer mode and approve custom apps for the organization.

Each user also needs their own Standard Metrics account to authenticate through OAuth.

## ChatGPT Web

### Enable developer mode

1. In ChatGPT, open **Settings** > **Security and login**.
2. Turn on **Developer mode**.

### Create the app

1. Open **Settings** > **Plugins**, or go directly to the [Plugins directory](https://chatgpt.com/plugins).
2. Click the plus button to create a developer-mode app.
3. Enter a name, such as `Standard Metrics`.
4. Use the following MCP server URL:

```text theme={null}
https://mcp.standardmetrics.io/mcp
```

5. Set **Authentication** to **OAuth**.
6. Save the app and connect it to your ChatGPT account.
7. Sign in with your Standard Metrics account and complete the authorization flow.

## ChatGPT Desktop

1. Go to **Settings** > **Plugins** > **MCPs**.
2. Click **Add server**.
3. Enter a name, such as `Standard Metrics`.
4. Select **Streamable HTTP** as the server type.
5. Enter the following MCP server URL:

```text theme={null}
https://mcp.standardmetrics.io/mcp
```

6. Save the server.
7. Click **Authenticate**.
8. Sign in with your Standard Metrics account and complete the authorization flow.

## Codex

Add the Standard Metrics MCP server to Codex from your terminal:

```bash theme={null}
codex mcp add standard-metrics --url https://mcp.standardmetrics.io/mcp
```

Then authenticate with your Standard Metrics account:

```bash theme={null}
codex mcp login standard-metrics
```

Complete the OAuth flow in your browser. Run `codex mcp list` from your terminal or `/mcp` inside Codex to check the connection. This configuration is shared by the Codex CLI and IDE extension.

## Test your connection

Ask ChatGPT or Codex:

If your client returns data from Standard Metrics, your connection is ready. If it does not, see [Troubleshooting](/guides/mcp-troubleshooting).
