sayou is an open-source, file-system-inspired MCP (Model Context Protocol) server that provides persistent, versioned context storage for AI assistants and agents. It exposes a suite of tools for managing versioned files, semantic and keyword search, key-value storage, knowledge graph building, and advanced querying. sayou integrates with Claude, Cursor, Windsurf, and any MCP-compatible client or agent, and functions through command-line, Python library, and optional REST API. It's aimed at developers, AI power users, and organizations seeking a persistent, auditable context/knowledge base for AI workflows across sessions and tools.
