FME can read and write the Mercator MCF format.
Overview
The Mercator MCF format is a collection of different types of data which include lines, areas, points, text, externals, and jobs. Each type of data is stored in a separate file, often with all the files of a particular dataset residing in the same folder. The files are stored in DTO format, have the extension .dto and are named <dataset name>_<file type identifier>.dto. The file type identifier is “l” for lines, “a” for areas, “p” for points, “e” for externals, “t” for text, and “j” for jobs.

Reader Overview
FME considers a Mercator MCF dataset to be a set of files in the same folder with the same dataset name. The reader produces FME features for all feature data held in files that reside in a particular folder.
The MCF reader extracts features one at a time and passes them on to the rest of the FME for further processing. When the file is exhausted, the reader starts on the next file. When all MCF files in the folder have been read, the reader is closed.
MCF uses an upper-left origin for its coordinates and FME uses a bottom-left origin. To compensate for this, all y values are multiplied by -1 to “flip” them over the x-axis.
