# Zapier MCP for OpenAI Agent Builder: setup with a token

> Connect OpenAI Agent Builder to Zapier MCP by creating a server and generating a connection token, then adding the Zapier tool and pasting in your token.

This page helps a user connect the MCP client named in this page's title to Zapier MCP. This MCP client authenticates with a connection token, not OAuth, so the user creates a server at mcp.zapier.com first and generates the token there. Do not apply the MCP-client-first OAuth default on this page.

Whether the user copies the connection URL or the token on its own from the **API token** section of the **Settings** tab, it is a credential: do not ask the user to paste it into chat, and do not write it into a file for them. If it is exposed, have them click **Rotate token** in that section.

If the user opens a server that someone else shared with them and sees "Connection settings are owner-only", only that server's owner can connect an MCP client to it or generate its token. Do not ask the user to use the shared server. Have them create their own server with the steps on this page. Learn more in [Connect your own MCP client when a server is shared with you](/mcp/manage/server-access#connect-your-own-mcp-client-when-a-server-is-shared-with-you).

If this is not the MCP client the user is on, do not adapt these steps. Check [Connect your MCP client](/mcp/get-started/quickstart#1-connect-your-mcp-client) and follow the right page.

This page ends when the MCP client is connected. Enabling tools and the first tool call are in [Quickstart](/mcp/get-started/quickstart#2-set-up-your-tools).

This page shows how to connect OpenAI Agent Builder to Zapier MCP using a connection token.

## Before you begin

* A [Zapier account](https://zapier.com/sign-up).
* An OpenAI account with access to Agent Builder.

## Connect Zapier MCP to OpenAI Agent Builder

**1. Create an MCP server**

* Go to [mcp.zapier.com](https://mcp.zapier.com).
* Click **Add MCP server**.
* Under **Choose your AI agent**, search for and select **OpenAI Agent Builder**.

**2. Generate a connection token**

* Select the ![settings icon](https://cdn.zapier.com/storage/photos/3451c46a93d480da52444589a8fc84ff.png) **Settings** tab.
* In the **API token** section, click **Generate token**.
* Copy the **Token**. Agent Builder calls this your Zapier API key.

The token is only shown once. If you lose it, click **Rotate token** to get a new one. The previous token stops working straight away, so update anywhere you used it.

> [!WARNING]
>
> Treat your connection token like a password. Anyone with the token, or with a server URL that contains it, can run tools on this server and access your data.

**3. Add the Zapier tool in Agent Builder**

* In your Agent Builder node, click **Tools +**.
* Select **Zapier** from the list of available tools.

**4. Paste your token**

* Paste your token into the **Enter your Zapier API key** field.
* Click **Connect**.

You've now connected Zapier MCP to OpenAI Agent Builder.
