Coconut oil and/or other oils contain pure fats. Technically speaking, anything that has calories, even if it is a tiny amount break your fast. However, fat has little to no effect on insulin, blood glucose, or any of the other measurements that indicate a “broken fast.” For this reason, it could be considered as part of fasting, as popularized by Bulletproof fasting.

If you prefer 'clean' fasting though (something we recommend for our 21 Day Intermittent Fasting Challenge), you should try to sustain from consuming any oils and/or butter, and hence sustain from Bulletproof coffee during your fasting hours. Also, note that fats are extremely high in calories hence you should keep this in mind if you are trying to lose weight.
