This is duplicate of another ticket (a feature request) where is asked to allow use WCS layer as input layers for Processing tools, at the moment they are not supported.

Actually they work for native QGIS algorithms, just not the gdal based ones

mapserver wcs layers do not show as input for qgis core tools. GDAL tools give an error like "FAILURE: No target dataset specified.".

Hmm - that's a bug in itself. They do work, they are just filtered from the GUI. I'll fix.

Actually I can't confirm this - if I add a WCS layer I can pick it as an input for native tools like "Raster Surface Volume", "Reclassify by table", etc. It's slow, but that's expected when working directly with a remote source like WCS...

you are right, I tried again and it seems to work here too... weird, probably I hit a glitch.
