Documentation for mcp command flags

[alnickle]

Is your feature request related to a problem? Please describe.
The documentation doesn't mention the -t, --transport command flag for mcp run <filename>.py. I was unable to get Cursor to connect to my locally-running MCP server correctly without explicitly setting the transport flag, which I only discovered from reading the code (running in Ubuntu).

Describe the solution you'd like
The -t, --transport flag (and all other flags for mcp commands) should be documented in the README.md so that devs and LLMs alike can have the necessary context to connect.

Fair feedback - looking at the README there's scarcely any documentation on the CLI, seems important to add.

I'd like to work on this. Added a CLI command flags reference section to README.v2.md documenting all flags for mcp run, mcp dev, and mcp install, including the -t/--transport flag.
