Configure the Zapier MCP Server

Overview

Zapier operates an official hosted MCP server at mcp.zapier.com, proxying actions across the apps already connected to your Zapier account. Access is authorized through OAuth with dynamic client registration.

1. Configure Zapier

2. Add the MCP server to your gateway config

Go to your gateway in the Dtwo UI and open Configuration → Advanced. In the mcp_servers section add the following entry:

  - name: zapier
    description: "Zapier's official hosted MCP server for your connected apps and actions."
    url: https://mcp.zapier.com/api/v1/connect
    transport_type: streamablehttp
    authentication:
      type: oauth
      grant_type: authorization_code
      scopes:
        - default
      issuer: "https://mcp.zapier.com"
      redirect_uri: "<CALLBACK_URL>"
      pkce_enabled: true

Replace the placeholder value:

<CALLBACK_URL> — your Dtwo gateway’s OAuth callback URL, found in the Overview tab for your gateway in the Dtwo UI.

3. Deploy and verify

Save the configuration and deploy the gateway.

Then, in your AI client, ask it to authorize Zapier via the gateway. This opens Zapier’s OAuth consent page — sign in as the user whose connected apps the agent should use, and approve the consent prompt. Once authorized, confirm the server’s tools appear and run a quick call to make sure the connection works.

If the tools don’t appear after you authorize, refresh the tool list in your AI client — some clients don’t pick it up automatically.
