# 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 server URL or the token on its own from the **Connect** 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** on the **Connect** tab.

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

<Steps>
  <Step title="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**.
  </Step>

  <Step title="Generate a connection token">
    * Select the <img src="https://cdn.zapier.com/storage/photos/baa5b3a64988a15f0dc8497c52ec257b.png" alt="link icon" noZoom style={{ display: "inline-block", width: "14px", margin: "0 0.15em", verticalAlign: "baseline" }} /> **Connect** tab.
    * Under **Get your Zapier API Key**, 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.
    </Warning>
  </Step>

  <Step title="Add the Zapier tool in Agent Builder">
    * In your Agent Builder node, click **Tools +**.
    * Select **Zapier** from the list of available tools.
  </Step>

  <Step title="Paste your token">
    * Paste your token into the **Enter your Zapier API key** field.
    * Click **Connect**.
  </Step>
</Steps>

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