How to use OpenViking: what you can do with it

What is OpenViking? OpenViking is an open-source context database for AI agents that keeps knowledge, memory and skills in one virtual filesystem under viking:// paths. Directories carry generated one-sentence abstracts and overviews so agents can judge relevance before reading full files, and search can be scoped to a directory. Sessions are archived as Markdown memories you can read and edit. A memory plugin connects Claude Code, Codex, Cursor and OpenCode.

How do I use it? Have an OpenViking server running (self-hosted or the hosted service); then run curl -fsSL https://openviking.ai/install | bash and pick your tools and server when asked; use a user key, not a root key. Full steps below.

    Moved the OpenViking memory backend for his Hermes agent from a laptop Docker container into a k3s homelab

    OpenViking stored and recalled memories across sessions for the author's Hermes profile, but ran on a MacBook bound to 0.0.0.0:1933 with a shell script as monitoring. He moved it into his homelab k3s cluster and wrote the steps up as a copy-paste tutorial.

  • Built withGitHub

    Indexed about 2,000 local docs into OpenViking so Claude Code can search them over MCP

    A documented production setup maps an Obsidian vault (109 docs), a work directory (1000 docs) and personal projects (867 docs) into viking:// resources, and Claude Code queries them through MCP tools that return tiered L0, L1 and L2 summaries instead of whole files.

Quick start with OpenViking

  1. Check you have what it needs: uv and Python for a self-hosted server, or the hosted OpenViking Service; A model provider for the server (Volcengine, OpenAI, Codex OAuth, Kimi, GLM or local Ollama); A user key for the memory plugin (a root key cannot read or write memories).
  2. Open volcengine/OpenViking on GitHub and read the README and license.
  3. Have an OpenViking server running (self-hosted or the hosted service)
  4. Run curl -fsSL https://openviking.ai/install | bash and pick your tools and server when asked
  5. Use a user key, not a root key
  6. Restart your agent as the installer instructs, then follow the onboarding guide

These steps come from our top use case, Give Claude Code, Codex or Cursor memory across sessions, which also has a copy-paste agent prompt.
