# ChatGPT Web

### Note on ChatGPT support

> **INFO**
> Full support for MCP client access is currently in **beta** in ChatGPT. At the moment, it's only available in **Developer mode** for **Pro and Plus accounts on the web.**

While it's in beta, we recommend being as **explicit and precise as possible** in your prompts. For example:

- Mention the **Ahrefs MCP** directly.
- Specify the **tool or endpoint** to use.
- Indicate which **fields to pull** and how to **sort the results.**
- Excplicitly ask ChatGPT **not to use the web search.**

Better results often come from structured prompts like this:

*"Using the Ahrefs MCP connector and the `keywords-explorer-matching-terms` action, pull the top 10 keywords related to "marketing" in Brazil, sorted by search volume."*

instead of a vague prompt like:

*"What are the top keywords related to marketing in Brazil?"*

For the latest details, see the official [ChatGPT Developer Mode docs](https://platform.openai.com/docs/guides/developer-mode)
