How do you initialize a new MCP server with the Python SDK?

The Python MCP SDK makes server creation straightforward. You can initialize a new MCP server with just a single line of code that creates a server instance you can then attach tools, resources, and prompts to. For a document management example, you might also set up a simple in-memory data structure, like a dictionary where the keys are document identifiers and the values are the document contents. That dictionary is your storage for the lifetime of the server. Once the server instance exists, you decorate Python functions to register them as tools, and the SDK wires everything up automatically when the server starts.
