I can work on this!

I took a look at the attached PR.
Following are my findings:

1. we have an implementation of ToolAnnotations here.
2. In the attached PR it is said that we want ToolAnnotations to extend DisplayAnnotations, however I did not find DisplayAnnotations in schema.ts anymore

If you could give me some clarity on next step it would be helpful!

@AishwaryaKalloli thanks for offering to jump in! ToolAnnotations support was actually added in #482 (release 1.7.0), so this one's done (per your findings 😁 ) - closing the task.
