OpenViking

OpenViking is an open-source context database for AI agents that organizes memory, resources, and skills into a navigable directory.

OpenViking is a context database designed to unify agent memory, knowledge RAG, and skills into a navigable directory structure using viking:// paths. It helps developers and teams organize unstructured data, memories, and skills so that AI agents can read and write within explicit permissions. The system features an outer filesystem interface for active I/O and an inner automatic pipeline that parses, summarizes, indexes, and extracts memories. Supported tools include Claude Code, Codex, Cursor, TRAE, OpenCode, OpenClaw, Hermes, and MCP clients. It supports macOS and Linux environments with Node.js and curl, and offers cloud storage options via Volcengine.
