CKG-NVIDIA-AI
NVIDIA AI Developer Stack as Compressed Knowledge Graph (CKG) - 20 domains, 998 notes, agents traverse typed dependency edges instead of scanning docs.
Documentation
MCP — CKG-NVIDIA-AI
MCP server — Compressed Knowledge Graph (CKG) for the full NVIDIA AI developer stack.
4× F1 · 11× fewer tokens · 998 nodes · deterministic traversal.
Read-only. This MCP server never writes, mutates, or executes. Every response is a declared graph traversal — not inference, not retrieval, not generation.
The problem every AI team hits
More agents. More retrieval. More context. And accuracy drops.
This is the intelligence paradox: the more AI you add, the more tokens you burn re-discovering structure your system already knows — or could know. Research finds 73% of enterprise tokens are redundant context. In multi-agent pipelines, context efficiency collapses from 18.2 in Q1 to 1.6 by Q4 — 91% degradation with no model change.
The model is not the bottleneck. The context is.
Every time your agent calls out to ask what TensorRT-LLM requires to run on Hopper, it spends ~2,982 tokens re-inferring a relationship that could be declared once and traversed in 269. That difference compounds across every query, every agent, every boundary crossing.
The fix is not a better model. It is structured context.
What this package does
A CKG is a layer — a fast, inexpensive way to convert a large volume of domain documentation into structured, agent-traversable knowledge. Instead of retrieval, the agent traverses. Instead of inference, it reads declared relationships.
This package gives your agent the NVIDIA AI developer stack as its first layer: 20 domains, 998 nodes, every prerequisite chain declared and typed.
Layers stack. Context windows open.
| Layer | What your agent gains |
|---|---|
| NVIDIA AI docs (this package) | Platform prerequisites, deployment chains, hardware dependencies |
| Your domain | Company knowledge, internal APIs, product relationships |
| Competitive / market | Competitor stack, pricing, positioning — structured for traversal |
| Regulatory / compliance | Policy graphs, requirement chains, audit trails |
Each additional CKG layer costs your agent fewer tokens to operate, not more. Structured context is model augmentation — it does not replace what the model knows, it makes what it knows precise and auditable.
query_ckg("TensorRT-LLM", "nvidia-tensorrt-triton", depth=3)
→ TensorRT-LLM requires:
CUDA Toolkit → CUDA Driver API, cuBLAS
FP8 / FP4 Quantization → Hopper SM90 Architecture
TensorRT-LLM enables:
Triton Inference Server → NIM Microservice Runtime
That traversal cost 269 tokens. A RAG call over the same question costs ~2,982. The graph doesn't guess — it traverses.
Explore the graph
Once installed, paste this into Claude, Cursor, or any MCP client and see what comes back:
You have access to the nvidia-ai CKG. I want to understand what it actually takes to deploy
a real-time speech AI pipeline on NVIDIA Jetson at the edge — not the marketing version,
the real dependency chain.
Start here:
get_prerequisites("Riva ASR", "nvidia-riva")
Then follow the chain into the inference layer:
query_ckg("TensorRT-LLM", "nvidia-tensorrt-triton", depth=3)
Then map the edge hardware:
get_prerequisites("Jetson Orin NX", "nvidia-jetson")
Present the result as a layered architecture map — foundation at the bottom, application at the
top, typed edges (REQUIRES / ENABLES) labeled between layers. Show where the three domains share
prerequisites. Flag anything that would block a cold-start deployment.
The graph will traverse four domains, surface shared prerequisites, and show you exactly what stands between an idea and a running system — no hallucination, no guessing, just declared relationships. See what it gives you.

System prompt snippet
You have access to the nvidia-ai MCP server — a typed dependency graph of 20 NVIDIA AI domains
(NIM, NeMo, TensorRT, CUDA, Isaac, Cosmos, Riva, and 13 more). When answering questions about
NVIDIA infrastructure, prerequisites, or deployment, call query_ckg() or get_prerequisites()
before responding. Do not guess dependency chains — traverse the graph instead.
Accuracy model
Every edge was declared by a human reviewer. The graph is in active development — corrections arrive from the community weekly.
Three-state confidence:
| State | Meaning | How to use |
|---|---|---|
confidence: high | Reviewed, cross-referenced with NVIDIA docs | Trust for planning |
confidence: null | Plausible, not yet audited | Scaffold — verify before production |
confidence: low | Flagged as uncertain | Treat as a hint, not a fact |
Typed edges — semantic precision:
| Type | Meaning | Agent use |
|---|---|---|
REQUIRES | Hard prerequisite | Plan sequencing, gap detection |
ENABLES | Unlocks a capability | Optimization paths |
RELATES_TO | Conceptual proximity | Disambiguation, context |
IMPLEMENTS | Concrete instantiation | Architecture mapping |
If an edge isn't declared, the traversal returns nothing rather than hallucinating a path. That silence is signal.

Benchmark
Evaluated on KRB Benchmark v0.6.2 — open dataset, reproducible methodology, fixed baselines.
| System | Macro F1 | Tokens/query | Cost/1K queries |
|---|---|---|---|
| CKG | 0.471 | 269 | $7.81 |
| RAG (text-embedding-3-small) | 0.123 | 2,982 | $76.23 |
| GraphRAG (MS global mode) | 0.120 | — | — |
4× F1 · 11× fewer tokens · 5-hop F1 0.772 vs 0.170 · auditable by design
5-hop reasoning is where the gap compounds: retrieval degrades with each hop; graph traversal does not.
How the graph is built
Each domain is a DAG stored as typed edge CSV — human-authored and human-reviewed:
ConceptID, ConceptLabel, Dependencies, TaxonomyID
1, TensorRT-LLM, "", Framework
2, CUDA Toolkit, "", Platform
3, FP8 Quantization,"2:REQUIRES", Optimization
4, Hopper SM90, "2:REQUIRES", Architecture
5, Speculative Dec.,"1:REQUIRES|4:REQUIRES",Optimization
No embeddings. No vector index. No probabilistic retrieval. The graph is the compressed form — built once, reviewed once, traversed forever.
Why context efficiency collapses — and how CKG reverses it
Liu et al. (arXiv:2606.30986) formally quantify Context Transaction Cost (CTC): the compound tax paid every time context crosses an agent boundary. In multi-agent pipelines, CTC efficiency falls from 18.2 in Q1 to 1.6 by Q4 — 91% collapse with no model change.
CKG attacks all three root causes:
| CTC component | What it is | CKG's response |
|---|---|---|
| Token Latency Burden (τ) | Compute cost of transmitting context | 269 tokens instead of 2,982 |
| Handoff Cost (H) | Serialization loss at agent boundaries | get_prerequisites() replaces re-retrieval |
| Compression Loss (C) | Information destroyed when context is summarized | The graph is the compressed form — done once, offline |
Structured context doesn't consume your context window. It opens it.
The alternative to fine-tuning
When task-specific data is scarce, fine-tuning is often the first instinct — and frequently the wrong one. Fine-tuning requires thousands of labeled examples, a training budget, and a retraining cycle every time your domain shifts. By the time a large enterprise model project completes, the knowledge it was trained on is often already stale.
CKG encodes domain knowledge once as a typed graph. When the knowledge changes — new regulations, new product, new market — you update the graph. Not the model.
Directional intelligence, deployed today, updatable tomorrow — at 11× lower token cost.
The commercial case in three parts:
| Fine-tuning | CKG | |
|---|---|---|
| Speed | 6-month cycle before you see results | One session to deploy |
| Adaptability | Retrain when knowledge shifts | Update the graph, not the model |
| Sustainability | Expensive to run at scale | 269 tokens/query — 10,000 questions vs 1,000 |
The opponent isn't just fine-tuning — it's the perfectionism-as-procurement-strategy trap: 18 months and significant budget chasing the last few accuracy points while competitors ship directional answers at $7.81/query. Fine-tuning handles the final mile of specialization. CKG handles the knowledge architecture the fine-tuned model still needs to operate correctly.
Enterprise risk coverage:
| Risk | CKG response |
|---|---|
| Drift without version control | Typed, declared edges don't drift — every change is a graph update |
| Institutional knowledge lock-in | Human-readable, portable CSV — not vendor-locked |
| Provenance reconstruction failure | Every edge has a declared source and type — inherently auditable |
| New hire / auditor onboarding | CKG as runbook — traversable by anyone, not just the team that built it |
Corrections welcome
Spotted a wrong edge? A RELATES_TO that should be REQUIRES? A missing concept in Riva or Isaac?
Edge corrections are the highest-value contribution. The graph gets more useful with every fix. Open an issue or PR — see CONTRIBUTING.md for the review format.
