You can use the adapter directive for this.

class IHeaderProvider(zope.contentprovider.interfaces.IContentProvider):
    """Header provider."""

class HeaderProvider(object):
    """Header content provider."""

    zope.interface.implements(IHeaderProvider)
    zope.component.adapts(zope.interface.Interface, IMySkinBrowserLayer,
zope.interface.Interface)

<zope:adapter
    name="IHeaderProvider"
    factory=".header.HeaderProvider"
    />
