Is SNMP an option?

You can look at CISCO-VTP-MIB::vlanTrunkPortDynamicStatus to find out
the trunking status of an interface.  vlanTrunkPortVlansEnabled* will
give you a bitmask of the vlans that are permitted on a trunk.
vtpVlanName and vtpVlanState will tell you the basic info on a given
vlan.

CISCO-VLAN-MEMBERSHIP-MIB::vmVlan will show you vlans assigned to
access ports.
