Just use supers:
(supers (class {}))
=> #{clojure.lang.AFn java.lang.Iterable java.lang.Runnable
clojure.lang.IPersistentMap clojure.lang.IEditableCollection
clojure.lang.IObj clojure.lang.MapEquivalence java.io.Serializable
clojure.lang.IKVReduce clojure.lang.IMapIterable java.util.Map
clojure.lang.APersistentMap clojure.lang.IPersistentCollection
clojure.lang.IFn clojure.lang.Associative clojure.lang.Counted
clojure.lang.Seqable java.lang.Object clojure.lang.IHashEq
clojure.lang.IMeta clojure.lang.ILookup java.util.concurrent.Callable}
When in doubt, you can also experiment with other stuff found perusing The Clojure CheatSheet. For example:
(parents (class {})) =>
#{clojure.lang.IEditableCollection clojure.lang.IObj
clojure.lang.IKVReduce clojure.lang.IMapIterable
clojure.lang.APersistentMap}
(ancestors (class {})) =>
#{clojure.lang.AFn java.lang.Iterable java.lang.Runnable
clojure.lang.IPersistentMap clojure.lang.IEditableCollection
clojure.lang.IObj clojure.lang.MapEquivalence java.io.Serializable
clojure.lang.IKVReduce clojure.lang.IMapIterable java.util.Map
clojure.lang.APersistentMap clojure.lang.IPersistentCollection
clojure.lang.IFn clojure.lang.Associative clojure.lang.Counted
clojure.lang.Seqable java.lang.Object clojure.lang.IHashEq
clojure.lang.IMeta clojure.lang.ILookup java.util.concurrent.Callable}
(bases (class {})) =>
(clojure.lang.APersistentMap
clojure.lang.IObj
clojure.lang.IEditableCollection
clojure.lang.IMapIterable
clojure.lang.IKVReduce)
; Mostly synonyms
(class {}) => clojure.lang.PersistentArrayMap
(type {}) => clojure.lang.PersistentArrayMap

These are interfaces, not protocols. This won't cover any protocols you extend to a type after the type is already defined.

@akond I was referring more to the answer itself than your comment on it. If you're only looking at superclasses you might as well filter for interfaces, but either way you'll miss protocols extended after type definition.
