When I try to install crewai’s mcp-functionality using:

pip install crewai_tools[mcp]

I get following output:

At the end, only crewai_tools-0.0.1 is installed which is far beyond the current version and which does not include mcp.

Currently the Version 0.150.0 from crewai is installed, and I use the python version 3.13.5 with Windows.

Now I solved this issue by considering following changes to my original setup:

  • switching from Python 3.13 to 3.11
  • installing Visual Studio Build Tools: Due to my personal setup this was not possible at first; then I switched to PortableBuildTools.
