# Connect MoltSets to ChatGPT

> Add the MoltSets MCP server to ChatGPT as a custom connector, authorized with your OAuth Client ID and Secret.

ChatGPT connects to MCP servers through **Connectors** (formerly "Apps"), found in Settings.

**MCP Server URL**

```text theme={null}
https://mcp.moltsets.com/mcp
```

<Note>
  To get your credentials, log into [app.moltsets.com](https://app.moltsets.com) and go to **Connectors** to create a new connector.
</Note>

***

## Add the connector

1. Go to **Settings → Connectors** (or **Apps & Connectors**, depending on your ChatGPT version).
2. Select **Add custom connector**.
3. Enter:
   * **Name:** MoltSets
   * **MCP Server URL:** `https://mcp.moltsets.com/mcp`
4. When prompted for authentication, select **OAuth**.
5. Enter your **Client ID** and **Client Secret** from your MoltSets dashboard.
6. ChatGPT redirects you to [app.moltsets.com](https://app.moltsets.com) to log in and approve access, then returns you to ChatGPT.

Once connected, MoltSets tools are available to invoke from any conversation where you enable the connector.

<Note>
  Custom MCP connectors require a **Plus, Team, or Enterprise** plan — they aren't available on the free tier.
</Note>

<Warning>
  ChatGPT does not fall back to a static API key. If you only have a MoltSets API key (`ms_XXXXXXXXXXX`) rather than a Client ID / Client Secret pair, generate OAuth credentials from the **Connectors** page at [app.moltsets.com](https://app.moltsets.com) first.
</Warning>
