Introduction to MCP and Adzviser on Claude

Adzviser is now a fully supported MCP (Model Context Protocol (opens in a new tab)) server. We give digital marketers and ecommerce shop owners direct access to their real-time marketing and sales data on Claude.ai (opens in a new tab)—with support for more large language models (LLMs) coming soon.

However, what does this actually mean?

What is MCP?

MCP (opens in a new tab), or Model Context Protocol, is an open protocol that allows AI tools like Claude (opens in a new tab) to securely connect to external data sources. Think of it as a standardized way for large language models to fetch real-time information—such as your ad spend, conversions, or product sales—from trusted sources. With MCP, instead of uploading data or manually copy-pasting reports, the AI can fetch the data directly from your systems through a secure API.

This ensures:

• Security and privacy (your data stays under your control)

• Freshness (the AI is working with real-time data)

• Relevance (it answers questions based on your marketing context)

What is Adzviser’s Role?

Adzviser acts as your MCP server, serving as a secure middleware between your marketing data sources—like Google Ads, Facebook Ads, Google Analytics, and Shopify—and Claude. It connects to these platforms, retrieves real-time data, and makes it accessible to Claude through the MCP protocol. Once connected, you can ask Claude things like:

• "Which campaign had the highest return on ad spend last week?"

• "What was the geographic trend in website traffic after last month’s promotion?"

• "Show me products with the highest conversion rate from Meta ads."

And Claude will respond with insights drawn from your actual data—without needing you to lift a finger.

Why Use Claude Instead of ChatGPT?

While ChatGPT remains a powerful tool, we understand that many users prefer Claude for its data analytical capabilities, reasoning style, or over tone. With Adzviser’s MCP integration, you don’t have to choose—you can bring your marketing data to whichever LLM works best for your team.

So, if you’re a Claude user and want to make data-driven decisions faster, without toggling between dashboards or exporting CSVs, Adzviser on MCP is made for you.
