Installation readme is a bit misleading and points to the wrong version

[Aviglik91]

Hi Team,

Describe the bug
The project's readme suggests using FastMCP server (merged into mcp version 1.2.0rc1) but pypi offers mcp1.1.2 version which doesn't support FastMCP yet.

To Reproduce
Steps to reproduce the behavior:

1. uv add "mcp[cli]" # install mcp==1.1.2 version from pypi (the official version)
2. mcp dev server

Expected behavior
Relevant docs need to clearly indicate that FastMCP server feature requires version 1.2.0rc1 which is not yet available on PyPI by default . Users following the readme are currently unable to use the documented FastMCP features with the stable PyPI version.

Screenshots

Desktop (please complete the following information):

• OS: macOS Sonoma
• Package Version: mcp 1.1.2

Smartphone (please complete the following information):
N/A

Additional context
The documentation should either indicate that FastMCP server features are only available in the RC version (1.2.0rc1) or provide instructions for installing the RC version if users want to use these features. This would prevent confusion for users following the readme.

To install the 1.2.0rc1 locally:

uv add "mcp[cli]===1.2.0rc1"
