dreamgraph

Overview

DreamGraph is a comprehensive MCP server that combines a daemon, CLI, VS Code extension, and dashboard with a persistent knowledge graph. It maintains structured relationships between features, workflows, data models, and architecture decisions, allowing the system to answer from accumulated project understanding rather than just single file reads. It supports multi-repo systems, database introspection, and plugin development through its SDK.
