This project provides a Model Context Protocol (MCP) server that equips AI assistants with tools to effectively work with NIST's Open Security Controls Assessment Language (OSCAL). It addresses the challenge of AI agents alone producing inconsistent results related to OSCAL by offering authoritative guidance and enabling GRC workflow automation.
