Requirement name mcp matches project name mcp

[SHTechBoBo]

When I run the first step uv add "mcp[cli]",

it said:
error: Requirement name `mcp` matches project name `mcp`, but self-dependencies are not permitted without the `--dev` or `--optional` flags. If your project name (`mcp`) is shadowing that of a third-party dependency, consider renaming the project.

I guess something wrong in pyproject.toml, but I don't know how to solve it.

Well, it says what you have to do 😄.
Your own project may not be called "mcp" if you add a dependency called "mcp".
Solution: Rename your own project to something else. (-> change project.name in pyproject.toml)

This is a genuine issue though no? If you pull the project and follow the installation instructions you get an error right off the bat

Try:
uv add "mcp[cli]" --dev
