Integrate Dify with Live Google Campaign Manager 360 Data via CData Connect AI

Dify is an open source platform for building production-ready agentic workflows, chatbots, and other LLM applications. It includes built-in, two-way support for the model context protocol (MCP), allowing you to register remote MCP servers as tools in the platform to add external data sources and give your agents access to live data.

By integrating Dify with CData Connect AI through the built-in MCP Server, Dify gains governed, real-time access to live Google Campaign Manager 360 data. You can list catalogs, explore schemas, and query records from Google Campaign Manager 360 data using natural language prompts, with all data access running securely against authorized sources.

This article explains how to configure Google Campaign Manager 360 connectivity in Connect AI, generate the required personal access token, register the Connect AI MCP Server as a tool in Dify, add it to an agent application, and verify the integration by querying live Google Campaign Manager 360 data from Dify.

Step 1: Configure Google Campaign Manager 360 connectivity for Dify

Connectivity to Google Campaign Manager 360 from Dify is made possible through Connect AI's Remote MCP Server. To interact with Google Campaign Manager 360 data from Dify, start by creating and configuring a Google Campaign Manager 360 connection in Connect AI.

1. Log into Connect AI, click Sources, and then click Add Connection

2. Select Google Campaign Manager 360 from the Add Connection panel

3. Enter the necessary authentication properties to connect to Google Campaign Manager 360.

   Google Campaign Manager uses the OAuth authentication standard. The data provider facilitates OAuth in various ways as described below. The following OAuth flow requires the authenticating user to interact with DoubleClick Campaign Manager, using the browser. You can also use a service account to authenticate.

   For authentication guides, see the Getting Started section of the data provider help documentation.

   
4. Click Save & Test
5. Navigate to the Permissions tab and update user-based permissions

Add a Personal Access Token

A Personal Access Token (PAT) is used to authenticate the connection to Connect AI from Dify. It is best practice to create a separate PAT for each integration to maintain granular access control.

1. Click the gear icon () at the top right of the Connect AI app to open Settings
2. On the Settings page, go to the Access Tokens section and click Create PAT
3. Give the PAT a descriptive name and click Create

4. Copy the token when displayed and store it securely. It will not be shown again

With the Google Campaign Manager 360 connection configured and a PAT generated, Dify can now connect to Google Campaign Manager 360 data through Connect AI.

Step 2: Register the Connect AI MCP Server in Dify

Next, register the Connect AI Remote MCP Server as a tool in Dify so your agents and workflows can discover and call live data tools through Connect AI.

1. Log into Dify, or open your self-hosted Dify instance (version 1.6.0 or later, which includes built-in MCP support)
2. Navigate to the Integrations page, select Tools and click MCP tab

3. Click Add MCP Server (HTTP) and enter the following details:
   • Server URL: https://mcp.cloud.cdata.com/mcp
   • Name Icon: Give a descriptive name, for example, CData Connect AI
   • Server Identifier: A unique identifier, for example, cdata-connect-ai
   • Headers: Add an Authorization header with the value Basic your_base64_encoded_email_PAT

   Note: Dify will use Basic authentication with Connect AI. Combine your Connect AI user email and the PAT you created earlier in the format email:PAT, base64 encode the combined string, and prefix it with Basic.

4. Click Add & Authorize. Dify connects to the Connect AI MCP Server and lists the available tools

With the MCP server registered, the Connect AI tools are available to any agent application or workflow in your Dify workspace.

Step 3: Query live Google Campaign Manager 360 data from Dify

With the integration complete, build an agent application in Dify and interact with live Google Campaign Manager 360 data through natural language prompts.

1. From the Dify Studio page, click Create from Blank and select Agent as the application type
2. In the agent configuration, click Add under the Tools section and select the Connect AI MCP tools registered in Step 2
3. Select an LLM provider and model for the agent so it can interpret prompts and call MCP tools
4. In the preview panel, type a prompt in the chat input, for example:
   • Use the cdata-connect-ai tools to list all available catalogs
   • Show the available schemas and tables for Google Campaign Manager 360
   • Query the top 5 records from a table in Google Campaign Manager 360
5. The Dify agent calls the Connect AI MCP Server and returns live results from Google Campaign Manager 360 data

At this point, Dify communicates with the Connect AI MCP Server and retrieves live Google Campaign Manager 360 data through remote MCP tools directly from your agentic workflows.
