```
» do a Web Search for HF inference providers on Brave Search and open the first result and then give me the list of the inference providers supported on Hugging Face

To accomplish this task, I'll follow these steps:

1. Navigate to the Brave Search website.
2. Perform a search for "HF inference providers".
3. Open the first result from the search.
4. Identify the section on the page that lists the inference providers supported by Hugging Face.
5. Extract the list of inference providers from that section.

Let's start by navigating to the Brave Search website.
browser_navigate {"url": "https://search.brave.com"}
...
Now that we're on the Brave Search homepage, let's type in the search query "HF inference providers" and submit the search.

browser_type {"element": "Search", "ref": "e22", "text": "HF inference providers", "submit": true}

It looks like we've encountered a CAPTCHA. To proceed, we need to solve the CAPTCHA. However, solving CAPTCHAs automatically is not allowed due to ethical and legal reasons.

Could you please help by solving the CAPTCHA manually? Once you've done that, let me know so I can continue the search and extract the information you need.
» I see that the CAPTCHA has been solved. Let's proceed by taking a snapshot of the search results page to identify the first result and then navigate to it.

It seems the CAPTCHA is still present, and the error message indicates that the server is responding with a status of 429, which means there are too many requests. This might be causing the CAPTCHA to reappear.

Could you please confirm if the CAPTCHA has been solved manually and if the page has loaded the search results? If not, you might need to solve it again. Once you have solved the CAPTCHA, let me know so I can capture the search results and proceed.

Start by opening the Unit 1 MCP Clients page linked in the report and reproducing the Brave Search flow. Check the exercise instructions around the CAPTCHA response; done means the documented task can proceed to the first result and retrieve the supported inference-provider list without stopping at this failure.
