sending files via MFT

MFT isn't just a protocol, like SFTP or HTTPS, it's a solution that includes a more-or-less standardized set of steps to ensure the security of data transfer. I really recommend you read the description on Wikipedia.

So, no, CF isn't able to provide an MFT client by changing the CFFTP tag to CFMFT or something like that. But you could build a complete MFT solution with CF, if it still uses a standard file transfer protocol like SFTP wrapped in non-repudiation, logging, external authentication & authorization, and whatever else is in MFT. You'd want to spend some time learning about the specific MFT solution you need to work with.
