# MRCM Maintenance Tool

The MRCM Maintenance Tool supports browsing, creation, testing, review and publication of MRCM rules used in the SNOMED CT Authoring Platform and included in SNOMED CT releases for conformance checking.

  The SNOMED International Content Team will use the tool to review, create, modify, inactivate and promote MRCM rule changes.
