MCP python-sdk vs. FastMCP 2.0

[martimfasantos]

Hello,

I’m starting to build a production-ready MCP server and I’m trying to choose between two frameworks - FastMCP 2.0 and python-sdk.

Does anyone have solid, experience-based opinions on them?

I’m already aware of the Prefect vs. Anthropic situation and what happened in V1, but I’d like to base my decision on practical differences between the two options.

For instance, I built a simple server example using OAuth with the python-sdk, and it didn’t seem like much was missing compared to what FastMCP 2.0 provides. Since OAuth support is one of the features FastMCP claims to offer on top of the official SDK, I’m wondering if I’m overlooking something.

I’m currently leaning toward FastMCP, but the “official” SDK feels more promising and potentially easier to adopt for a production environment.

Any insights would be appreciated!
