Migrating from mcp to fastmcp

[yarnabrina]

Hi, I was doing some personal POC to explore wghat is MCP and what are different features and created a repository here: github.com/yarnabrina/learn-model-context-protocol

Now, I am curious to try out fastmcp as I heard a lot of it from colleagues, but having some difficult time to migrate even mcp server, ignoring clients for now. One of the very simple areas I am struggling is where I am declaring tools but not using decorators. In mcp, @tool decorator and .add_tool method work similarly, but that does not seem to be same in fastmcp v3, where add_tool expect a Tool object and I couldn't find what to use to create that without switching to private properties.

Will appreciate some guidance.
