OpenViking - Context Database for AI Agents
OpenViking is ByteDance's open-source Context Database designed for AI Agents — a next-generation RAG system that replaces flat vector storage with a filesystem paradigm for managing memories, resources, and skills.
Key Features:
- Filesystem paradigm: Organize context like files with URIs (
viking://resources/...) - Tiered context (L0/L1/L2): Abstract → Overview → Full content, loaded on demand
- Directory recursive retrieval: Better accuracy than flat vector search
- MCP server included: Full RAG pipeline via Model Context Protocol
Quick Check: Is It Set Up?
test -f ~/code/openviking/examples/mcp-query/ov.conf && echo "Ready" || echo "Needs setup"
curl -s http://localhost:2033/mcp && echo "Running" || echo "Not running"
If Not Set Up → Initialize
Run the init script (one-time):
bash ~/.openclaw/skills/openviking-mcp/scripts/init.sh
This will:
- Clone OpenViking from
https://github.com/volcengine/OpenViking - Install dependencies with
uv sync - Create
ov.conftemplate - Pause for you to add API keys (embedding.dense.api_key, vlm.api_key)
Required: Volcengine/Ark API Keys
| Config Key | Purpose |
|---|---|
embedding.dense.api_key |
Semantic search embeddings |
vlm.api_key |
LLM for answer generation |
Get keys from: https://console.volcengine.com/ark
Start the Server
cd ~/code/openviking/examples/mcp-query
uv run server.py
Options:
--port 2033- Listen port--host 127.0.0.1- Bind address--data ./data- Data directory
Server will be at: http://127.0.0.1:2033/mcp
Connect to Claude
claude mcp add --transport http openviking http://localhost:2033/mcp
Or add to ~/.mcp.json:
{
"mcpServers": {
"openviking": {
"type": "http",
"url": "http://localhost:2033/mcp"
}
}
}
Tools Available
| Tool | Description |
|---|---|
query |
Full RAG pipeline — search + LLM answer |
search |
Semantic search only, returns docs |
add_resource |
Add files, directories, or URLs |
Example Usage
Once connected via MCP:
"Query: What is OpenViking?"
"Search: machine learning papers"
"Add https://example.com/article to knowledge base"
"Add ~/documents/report.pdf"
Troubleshooting
| Issue | Fix |
|---|---|
| Port in use | uv run server.py --port 2034 |
| Auth errors | Check API keys in ov.conf |
| Server not found | Ensure it's running: curl localhost:2033/mcp |

- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install openviking - After installation, invoke the skill by name or use
/openviking - Provide required inputs per the skill's parameter spec and get structured output
What is OpenViking?
RAG and semantic search via OpenViking Context Database MCP server. Query documents, search knowledge base, add files/URLs to vector memory. Use for document Q&A, knowledge management, AI agent memory, file search, semantic retrieval. Triggers on "openviking", "search documents", "semantic search", "knowledge base", "vector database", "RAG", "query pdf", "document query", "add resource". It is an AI Agent Skill for Claude Code / OpenClaw, with 4941 downloads so far.
