Sheldon is right. If you use the R code that we provide with the release of the Pipeline for Cancer Inference, it will fetch all the clinical information that you need. The code has a lot of comments, and you should be able to find where we extract the MSI/MSS clinical status from TCGA data

Can I get TCGA somatic mutation vcf files or maf files for MSI - H, MSI-L - MSS samples?
I mean open access without any special access and authorizations?
You can get some data from GDC portal: https://portal.gdc.cancer.gov/analysis_page?app= and https://portal.gdc.cancer.gov/analysis_page?app=Downloads
Most of sensitive data types (VCF) are going to require permission.
