What he knows
Full query-language syntax and semantics — verifiable, cited.
Deployment, clustering, backup, security.
Algorithms, embeddings, pipelines, projections.
The real procedures. No inventions.
Vector indexes, embeddings, similarity functions.
Modeling foundations done right.
Language drivers and integration patterns.
Managed-cloud specifics and limits.
Oscar ingests new machine-learning research around the clock — 38,000+ documents so far, woven into a knowledge graph of 720,000+ nodes and 1,000,000+ relationships. GraphRAG, agent memory, graph ML — his knowledge moves with the field, not a training cutoff.
Quickstart
claude mcp add oscar -- npx -y github:theastraway/oscar
Free tier needs no signup, no key. Pro users add OSCAR_API_KEY. Full docs on GitHub.
Pricing
$20/month is what developers already pay for a serious AI assistant — Oscar is the one that specializes. A human Neo4j consultant bills more than this per quarter hour.
Why he exists
Every agent we ship at Astra AI gets reviewed by an internal expert — a scholarly, slightly ruthless AI librarian who checks their work against actual documentation, not vibes. That's Oscar. He runs our lab: grading agents daily, opening tickets on what's weak, and maintaining the models and ontology everything else relies on.
He made our agents smarter. Now he can make yours smarter too. Backed by MIND, Astra AI's persistent memory and knowledge-graph platform, Oscar remembers your project context across sessions — the second conversation starts where the first one ended.
