Meaning of that tag is unclear[1] and it is dubious whatever it should be present on any object.

In it is defined as "Current urban area central place indicator" and restricted to be string of length 1.

In OSM database values tiger:CPI=Y and tiger:CPI=N clearly dominate[2] what suggests that it may be boolean value. Though it is not clear whatever yes/no applies to "Current" part, "urban" part or some other segment of definition.
