Your Question

I'm trying to get started with writing a client. But I'm stuck with setting up the barebones example.

I saved the FastMCP Echo-Server Example as example_server.py and start the server with mcp run example_server.py. But when I run the Writing MCP Clients Example, the script hangs at "Initialize the connection".

Any pointers? This is most likely a communication problem, but I'd like to start with a simple running example.
