Analyzing bol.com data with AI: how to use MCP

You can ask an AI why a campaign is performing less well. Without data about that campaign you mainly get general advice. With an MCP connection a suitable AI client can retrieve allowed data from your software and use it in its answer.

For bol.com sellers Zoloo MCP makes such a connection with Zoloo possible. What your client can request depends on your account, your rights and the available tools. That requires a different workflow than pasting an export into a chat: you first choose the access and then check what the AI does with the data.

In this guide you start with a read-only question. The example questions are meant for you to test yourself; they are not results from a real customer account.

What is MCP?

MCP stands for Model Context Protocol. It is an open standard that lets AI clients use data and functions from other software. The client sends a request to an available tool. The MCP server checks that request, executes it and returns a response.

The AI client then creates an explanation or proposal from that. The server is therefore not the AI model, and a connection does not automatically make the model’s conclusion correct.

With Zoloo MCP it is about access to Zoloo. The rights of your connection determine which tools the client sees, and your role in the account remains valid. A question in plain language cannot add rights that your account or connection does not have.

On the page about the Zoloo MCP server for bol.com data you can read what the connection does. It is a Zoloo connection; bol.com does not publish this server itself.

First choose one question about your store

A broad request like “optimize my business” gives little guidance. You don’t know which period the AI looks at, which data it needs or when the answer is complete.

Prefer a question whose source you can verify. For example start with the performance of your Sponsored Products campaigns. Specify a period and ask first for an overview, not for adjustments.

Summarize the available campaign performance of the past seven days. Mention the period used and data source. Indicate which data are missing. Which campaigns deserve further investigation? Change nothing.

This question forces the AI to make the limits of the answer visible. You want to know whether it has full campaign data, a limited selection or no access at all. A tool error should remain an error message, not a fabricated summary.

Then check in Zoloo whether you are looking at the same period and campaigns. When comparing, also pay attention to the moment data are updated. A difference in reporting period can already be enough for two overviews to tell different stories. If you first want to understand how the main advertising metric works, read what ACoS is and how to calculate it.

Use inventory data as a signal, not as ordering advice

A second use case is organizing your inventory data. Let the AI first describe what is available before you ask it for a conclusion.

Show the available inventory data of my listings. Sort by the lowest stock. Identify missing data and change nothing.

This does not yet give you a purchasing recommendation. To determine how much to order you need more: sales velocity, lead time, expected demand and stock that may already be in transit. Not every connection has all that information.

Therefore ask the AI to clearly state which data are missing for the next step. “Insufficient data to determine an order quantity” is more useful than an exact number without justification.

Distinguish between measurements and estimates

In product research, estimates sit alongside measured data. For example, the monthly sales of a tracked product is an estimate, while the price is a measured value. That difference should remain in the summary.

Summarize the available data about my tracked products. Distinguish between estimates and measured figures. Mention the period and indicate which information is missing.

An AI can combine multiple sources into one smooth paragraph. That reads well, but can hide that one value is an estimate and the other comes from your own account. Ask to keep that provenance explicit. How you track product sales data you can read in the guide about the bol.com sales tracker.

Also pay attention to the purpose of your question. An estimate can be useful for comparing products without being suitable for your accounting. That does not change just because an AI adds a convincing explanation.

Give the client as few rights as possible

Start with read-only permissions for the application you want to test. A question about ad performance does not need access to your finances or orders.

In Zoloo you see under Settings → AI-agents (MCP) which keys and connected apps you have, and you can adjust the rights per component for each key. Claude Desktop and Claude Code log in with your Zoloo account; you then approve the connection on a page of Zoloo. Other clients use an MCP key, which you place in the configuration field or the secret storage of the client.

Never paste passwords, bol.com API secrets or MCP keys into a regular chat. A key belongs only in your client’s settings, not in a message to the AI.

Revoke access when you no longer use the connection or see something unexpected. Also consider that data the client has already received falls under the data policy of your AI provider. Stopping future access is not the same as deleting previous conversations with that provider.

The Zoloo MCP setup guide describes how to connect per client.

An analysis is not an instruction to change anything

Reading and modifying each require their own decision. You can ask an AI which campaign deserves attention without instructing it to adjust a budget, bid or setting.

Let a proposal be explained first:

• What problem does the AI see in the available data?
• Based on which period and source is that?
• What information is still missing?
• What exactly would the proposed change do?

Changing via Zoloo MCP is only possible where Zoloo has enabled it for your account and your key or connection has rights for it. Even then a change happens in two steps: first a preview, then a separate confirmation. For your first test, reading is enough.

Check your first answer before proceeding

Use a small test that you can recalculate or retrieve in Zoloo. Verify the account, the selected period and the source data. Then see whether the AI honestly names missing information and does nothing beyond your instruction. In Zoloo you also see under AI-agents (MCP) which tools your client has invoked.

An empty answer does not automatically mean you have no sales or campaigns. It can also mean that the requested information is unavailable, the tool is not permitted, or the connection is not working. If in doubt, ask to show the error or limitation and resolve that cause first.

If this is correct, expand the application step by step. That way you build a workflow you can verify, instead of handing all daily decisions over to a new integration immediately.

Frequently asked questions about AI and bol.com data

Do I need an MCP server to use AI?

No. You can also use AI without integration, for example for general explanations or for an export you share intentionally. MCP is handy when you want to give a suitable client access to permitted tools and data, without having to manually provide the same information for each question again.

Does every AI client work with Zoloo MCP?

Not automatically. Logging in with your Zoloo account works in Claude Desktop and Claude Code. Other clients can connect with an MCP key if they support MCP over Streamable HTTP with their own Authorization header. Follow the setup guide and check in Zoloo what is available for your account.

Is MCP the same as the bol.com Retailer API?

No. An API is an interface that allows software to use data and functions. MCP is a standardized way for an AI client to invoke tools. Zoloo MCP determines which Zoloo capabilities are available through that connection; it is not unlimited access to the bol.com Retailer API.

Can AI guarantee my sales figures or predict my profit?

An integration provides access to information, not a guarantee of an accurate prediction or better results. Check the source, the period and the assumptions. Treat estimates as estimates and evaluate decisions against your own situation.

Where do I start?

Check what Zoloo MCP does, verify your access and follow the setup guide for your AI client. Then choose one read-only question whose answer you can verify yourself in Zoloo.
