Remote file support for `mcp run`

[uhinze]

Description

I have a tiny MCP server published on Github (20 lines of Python). Instead of putting in 100x more plumbing work to get it published to PyPi, then have people clone/install, I'd rather just say: here is the uvx command to run it from the raw Github file.

uvx itself supports this kind of feature using the --from syntax, so a possible interface would be:

uvx --with "mcp[cli]" mcp run --from https://raw.githubusercontent.com/uhinze/domain-mcp/refs/heads/main/main.py

Hi @uhinze thank you for this submission.

@joshuazhou744's PR #1501 prompted me to re-evaluate this original issue a little more carefully.

I don't think the SDKs responsibility should be to support such "package manager"-y stuff and managing downloads. It seems like your example could be shared relatively easily with:

git clone https://github.com/uhinze/domain-mcp
cd domain-mcp
uv run mcp run main.py

Which doesn't feel terrible?
