How to use mcp server in adk cli

I added mcp server and it's working in adk web.

The final line in agent.py file looks like (from the documentation) 
root_agent = create_agent ()

This function returns the root agent

But I'm unable to call this through adk run command in cli.

For normal tools, I'm able to call the same script in adk web and adk run.
How to enable adk run for mcp tools?
