# FAQ

<details>

<summary>What is Gemini CLI?</summary>

Gemini CLI is Google's command-line AI tool that lets you interact with Gemini directly from your terminal. You can ask questions, analyze data, and get insights without leaving the command line. When connected to Coupler.io, Gemini CLI can access your business data from any supported source.

</details>

<details>

<summary>How does my data get to Gemini CLI?</summary>

Coupler.io creates a connector that Gemini CLI accesses through the MCP (Model Context Protocol) pattern. When you run a data flow with Gemini CLI as the destination, Coupler.io makes the data available through this connector. Gemini CLI then fetches the data on demand when you ask questions about it — no files are written to disk or stored locally.

</details>

<details>

<summary>Can I send data from multiple sources to Gemini CLI in one flow?</summary>

Yes. A single Coupler.io data flow supports multiple sources, and you can combine them using **Join** or **Append** transformations before the data reaches Gemini CLI. This is useful when you want to correlate data from different platforms — for example, combining Google Ads spend with TikTok Ads performance in a single session.

</details>

<details>

<summary>Do I need any special credentials to set up the Gemini CLI destination?</summary>

No. The Gemini CLI destination in Coupler.io does not require database credentials, OAuth, or API keys on the destination side. You just select Gemini CLI as your destination and run the flow. Authentication happens on the Gemini CLI side through your Google account.

</details>

<details>

<summary>How do I keep Gemini CLI's data up to date without re-running manually?</summary>

Once your data flow has completed a successful manual run, you can set up a **schedule** in Coupler.io to refresh the data automatically — hourly, daily, or at a custom interval. Gemini CLI will then have access to fresh data whenever you start a new session.

## 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.coupler.io/destinations/categories/ai/gemini/faq.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.
