description: z.optional(z.string()),

To Reproduce

N/A

Expected behavior

We should be able to create a resource on a server with a description, so that the LLM knows what to do with the resource. A workaround is to stuff this into the name but this is inconsistent with tools.

Additional context

I haven't checked yet if this is true for prompts too but it should be checked there as well.

Occasionally the SDK will trail additions to the spec. Pull requests welcome!
