Suggested change

	# Create virtual environment and activate it
	uv venv
	source .venv/bin/activate # On Windows use: .venv\Scripts\activate

There's no need to explicitly create and activate the virtual environment, uv takes care of that implicitly. See https://docs.astral.sh/uv/concepts/projects/layout/#the-project-environment

[tadeodonegana]

Thank you for your comment, @taha-yassine. I added it because the official MCP docs explicitly mention the virtual environment. It might be a good idea to review those docs as well.

I have removed the explicit creation of the virtual environment in this PR in order to proceed. Thanks!

Why would you need httpx? It's a dependency of mcp already.

[tadeodonegana]

Thank you for your comment, @Kludex.

I originally added it because the official MCP docs explicitly mention it—likely due to the example provided in the documentation.

Since, as you mentioned, the dependency isn’t needed to run the python-sdk, I’ve removed it from this PR. Gracias!

I appreciate the effort. I don't think we need additional instructions to create a project. If we want to go down the path, we should skip the explicit creation of the .venv, since uv run will manage this for us, and I don't want to confuse people with additional instructions about venv management.

[tadeodonegana]

I have applied the requested changes. @dsp-ant, I would appreciate another review of these changes to see if we can move forward. Thanks!
