Whatever you do do not simply put 1 to 1 rest apis to mcp tools. Really think about common workflows users want and make good abstractions for good chunks of work.

> FastMCP is the standard framework for building MCP applications Standardized by whom? In an era where technology exists that can lend the appearance of legitimacy to just about anyone, that kind of statement needs to be qualified.

I still dont fully understand the point of MCP servers. What do they provide that a skill doesnt? Maybe I've just used too many poorly written ones. Is there some sort of tool that can be expressed as an MCP and but not as an API or CLI command? Obviously we shouldnt map existing apis to MCP tools, but why would I used an MCP over just writing a new "agentic ready" api route?

Well it sure took "FastMCP" long enough. And the announcement lands at a time when its looking increasingly like CLI is the preferred method vs MCP. I'm sure in a few months time, even that will be out of date

Have FastMCP become the standard sdk? The docs is great, honestly way better than the official website modelcontextprotocol which most if its pages is ”under construction”.

MCP earns its keep in specific cases: when the agent has no shell access, when you need to keep credentials out of the prompt context, or when you want runtime tool discovery across teams. But I've built a few MCP servers and half of them would've been simpler as a CLI script the agent calls directly.
