Executive Summary

ColaFlow is a next-generation AI-powered project management system built on the Model Context Protocol (MCP). It aims to revolutionize team collaboration by making AI a first-class team member that can safely read, write, and manage project data while maintaining human oversight and control.

Vision Statement

"Flow your work, with AI in every loop."

Mission
