Can you suggest best automation tools for seo?

There are no automated SEO tools but the closest thing to it is self-replicating backlinks. If you visit one website and ask them to provide a link to your website then you will receive one backlink from your effort.

If you write a great article with useful content that people can use then people will continue to link to it. Multiple backlinks for much less effort.

Places like SEMRush and Ahrefs have automated reports emailed to you telling you what to do though that is just as helpful.
