Introduction

In this comprehensive overview, we explore the innovative Model Context Protocol (MCP) servers feature introduced within the AI Hub platform.

This new functionality significantly simplifies the process of connecting AI models to third-party tools and platforms, enabling seamless integration without the need for complex API configurations.

Originally pioneered by Entropic and later adopted by industry giants such as OpenAI, Google, and Microsoft, MCP servers are transforming how AI interacts with external services, making integrations more accessible and efficient for users of all skill levels.

This summary provides a detailed walkthrough of MCP servers, illustrating their setup, capabilities, and practical application through a Shopify store example. It emphasizes the ease of connection, the flexibility of tool usage, and the potential for creating powerful AI-driven workflows with minimal technical overhead.

What Are MCP Servers?

MCP servers are a protocol that allows AI models to access a wide array of tools via simple URL connections, bypassing traditional API call complexities. They serve as a bridge between AI models and external services, enabling:

• Simplified integration: Connect by inserting a URL, with optional API tokens.

• No need for individual API endpoint setup: Reduces setup time and technical barriers.

• Wide adoption: Initially introduced by Entropic, now supported by major platforms like OpenAI, Google, and Microsoft.

Key Features

Setting Up an MCP Server: Step-by-Step

1. Accessing MCP Servers in AI Hub

Navigate to the AI Hub interface, locate the MCP Servers section, and initiate a new connection by providing a name (e.g., Web Shop).

2. Configuring the Connection

• URL: Enter the base URL of the MCP server.

• Authentication: Specify if a Bearer token or custom headers are needed.

• Pre-existing Servers: Many are available, especially for platforms like OpenAI. For example, selecting Shopify provides a ready-made server.

3. Connecting to Shopify

• Select Shopify MCP server.

• Input the store URL (e.g., https://mystore.myshopify.com).

• Connect: The system automatically constructs the full URL, appending /mcp to the base.

4. Verifying the Connection

• Test the connection by listing available tools.

• Tools include:

  • Search product catalog

  • Get cart details

  • Update cart

  • Search shop policies and FAQs

  • Get product details

5. Using the Tools

Once connected, the AI can utilize these tools to perform various actions, such as retrieving product info, updating carts, or answering FAQs, all through conversational prompts.

Practical Example: Shopify Store Integration

Connecting and Testing

• After setup, initiate a test request within the flow builder.

• Use an OpenAI integration block, selecting create model response.

• Choose a model (e.g., GPT 4.1 mini) optimized for compatibility.

• Set parameters like max tokens (e.g., 2500) and temperature (e.g., 0.3).

Querying the Store

• Ask questions such as: "What products do you have?"

• The AI sends a request to the MCP server, which internally calls the relevant tools.

• The response includes product details, images, and pricing.

Response Breakdown

Example Output

"We currently have the following products:

• Jeans priced at $43

• White T-shirt"

The AI can also provide images, descriptions, and other product info, making the shopping experience conversational and dynamic.

Benefits of Using MCP Servers

• Streamlined Integration: Connect to complex platforms with a single URL.

• Reduced Development Time: No need to build custom API endpoints.

• Enhanced User Experience: Enable conversational searches and updates.

• Cost Efficiency: Use optimized models like GPT 4.1 mini for affordability.

• Customizability: Host your own MCP server with tailored functionalities.

Advanced Usage and Customization

Modifying the Model Response

• Change the model used for responses.

• Insert system messages to define AI persona, tone, and constraints.

• Store response IDs for tracking and further processing.

Selecting MCP Servers in Flows

• Use the dropdown menu to select your connected MCP server.

• Adjust max tokens and temperature for desired response behavior.

• Ask complex questions, such as product searches, cart updates, or policy inquiries.

Example: Shopping Cart Management

• Search for products.

• Add items to cart.

• Retrieve cart details.

• Proceed to checkout.

All these actions are handled seamlessly via MCP server calls, simplifying backend logic.

Extensibility and Hosting Your Own MCP Server

• You can host your own MCP server to extend functionalities.

• Connect it similarly by providing the URL and authentication details.

• This opens possibilities for custom tools, business-specific integrations, and advanced automation.
