# How connectors work

Connectors are the MCP servers powering your assistant. They decide what it can find — products, availability, anything else you expose.

<figure><img src="/files/PkNZ0BDFsBSJ9M1iME5a" alt="The Connectors tab — connector list on the left, the selected connector&#x27;s tools on the right"><figcaption><p>Connectors — the list on the left, the selected connector on the right</p></figcaption></figure>

Your connectors are listed on the left. Select one and it opens on the right, where you turn it on or off and choose which of its tools the assistant may call.

## Priority order

Connectors are an ordered list. **When two connectors expose a tool with the same name, the one higher in the list wins.** Drag a connector by the handle at the left of its row to reorder.

That is the mechanism for overriding a default — put your own connector above Maker MCP and expose a tool with the same name.

## Turning things off

Each connector has an `OFF` / `ON` toggle at the top of its pane. You can turn Maker MCP off entirely and run only on your own connectors.

To keep a connector but narrow it, leave it on and disallow the tools you don't want — see [Controlling tool access](/maker-greatstore/connectors/tool-access.md).

{% hint style="warning" %}
Turning off every connector leaves the assistant with no catalogue to search. It will still answer from [Adding sources](/maker-greatstore/knowledge/adding-sources.md), but it cannot find products.
{% endhint %}

## Revalidating

The refresh button beside **Add connector** re-checks every connector — useful after changing credentials, or after deploying a change to a server you run. Revalidating is also how a newly added tool shows up in the list.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.maker.co/maker-greatstore/connectors/how-connectors-work.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
