View with context filter

Hello,
i am using kickstart 2.16 and metatags rc2. I am talking about the view "Collection products" from commerce.
I try to add the description from the content type or from the vocabulary term to the meta description tag.

I'm not familiar with this, but I think I miss a token like
[term:description]
[content-type:description]
maybe somehow in conjunction with the context filter variable %1
In this case the content-type and the vocabulary-term are equal %1

Is this missing? Or am i doing something wrong?
Or is there another way? I can't search any longer :-(
Thanks
