Everything
The reference MCP server — exercises every primitive (tools, resources, prompts, sampling) at once. The one to point your client at first.
Everything is exactly what it sounds like — the MCP server that demonstrates every primitive in the protocol at once. Tools, resources, prompts, sampling, the lot. If you're learning MCP, this is the one you point your client at first. If you're building MCP, this is the one you test against. The reference, not a tutorial — and that's the right way around.

Git
