Introduction to MCP and Adzviser on Claude
Adzviser is now a fully supported MCP (Model Context Protocol) server. We give digital marketers and ecommerce shop owners direct access to their marketing and sales reporting data on Claude.ai. You can also use Adzviser with ChatGPT, Gemini CLI, Perplexity, Manus, and OpenClaw.
However, what does this actually mean?
What is MCP?
MCP, or Model Context Protocol, is an open protocol that allows AI tools like Claude to securely connect to external data sources. Think of it as a standardized way for large language models to fetch the latest available 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 can request the latest data available from each source); source processing and attribution delays still apply.
-
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 the latest available reporting 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.
