Your use-case is a little unusual. MVT format was intended to efficiently deliver vector information from a server to a mapping client, usually something like OpenLayers or Leaflet running in a browser. Is there a specific reason you want to have Mapserver read the data?

I'm trying to add an MVT layer to my Mapfile, but it doesn't work and I ran out of ideas. Some info about the layer I'm trying to add: https://support.regrid.com/articles/using-the-tileserver/ This is my LAYER definition in my Mapfile (based on the guidance of https://gdal.org/drivers/vector/mvt.html and https://mapserver.org/input/vector/ogr.html) LAYER NAME "Parcel" TYPE POLYGON CONNECTIONTYPE OGR CONNECTION "MVT:https://tiles.regrid.com/api/v1/parcels/{z}"; DATA "parcels" STATUS ON END By debugging the layer I get the following logs: [Thu Dec 30 12:17:42 2021].906000 msOGRFileOpen(MVT:https://tiles.regrid.com/api/v1/parcels/{z})...

I'm expecting this to work because the following ogrinfo command runs without any issues: ogrinfo "MVT:https://tiles.regrid.com/api/v1/parcels/14/3579/6522.mvt"; parcels I couldn't find a single example online about adding an MVT layer to a Mapfile. Is there anyone who could prompt me in the right direction or just have a working example?
