VeritasGraph
Provides an MCP bridge integration for Unity, allowing AI agents to interact with Unity applications or data through the VeritasGraph server.
๏ปฟ# VeritasGraph โ The Governed, On-Prem GraphRAG & Agent Framework
Stop chunking blindly. Combine Tree-Search structure with Knowledge-Graph reasoning โ and wire it into governed AI agents. Runs 100% locally or in the cloud.
๐ฏ Traditional RAG guesses based on similarity. VeritasGraph reasons based on structure. Don't just find the document โ understand the connection, then act on it with governed agents.

๐ ๏ธ VeritasGraph Studio โ Build, wire & test governed agents locally
Studio is a local Agent Build Workspace (FastAPI + single-page UI) that lets you build a knowledge graph from your own documents and wire it into agents alongside tools, memory, data logging, guardrails, and headroom-style context budgeting โ then chat with those agents live and watch every stage of the orchestration pipeline. Everything runs 100% locally against Ollama.
๐ฎ Try the Studio Live โ stable URL that always redirects to the current running studio tunnel.
Run it:
pip install -r requirements.txt

๐ก What you're seeing: a query triggers multi-hop reasoning across the knowledge graph. Nodes light up as connections are discovered, showing exactly how the answer was found โ not just what was found.
๐ MCP Server โ connect your IDE agent to VeritasGraph
VeritasGraph ships a dedicated Model Context Protocol server โ the first zero-trust, air-gapped Enterprise GraphRAG server for MCP. Connect Claude Desktop, Cursor, VS Code, Windsurf, Cline, or Continue directly to the GraphRAG engine over JSON-RPC 2.0 stdio, with zero external data egress.
python -m veritasgraph_mcp # from repo root (needs local Ollama for ingest/query)Tools: veritasgraph_ingest_document, veritasgraph_query (multi-hop answers with [doc#chunk] citations), veritasgraph_search_entities, veritasgraph_get_graph, veritasgraph_clear_graph. See veritasgraph_mcp/README.md for IDE registration snippets.

GraphRAG is brilliant at describing what your documents say. But enterprise questions like "Which purchase orders violated our Segregation-of-Duties policy last quarter?" are rule-evaluation problems over structured records โ not similarity search.
For those, VeritasGraph ships a sister module: VeritasReason โ a deterministic reasoning engine (forward-chaining + Rete + SPARQL) that fires policy rules over a triplet store and returns auditable answers with W3C PROV-O provenance.

Compliance answer + violators table + clause citations30-second smoke test (no install, stdlib only)
python tests/test_policy_compliance_demo.pySeeds a fake ERP into a tiny in-memory triple store, evaluates four SoD rules from rules/sod_policy.yaml, and prints violators with citations:
โ Reasoner fired. Detected 4 violation(s):
po:PO-2204 SOD-01 Approved & paid by emp:E118
po:PO-2301 SOD-02 Requested & approved by emp:E091
po:PO-2317 SOD-03 $48,750.00 approved by emp:E091 (role:Manager, not Director)
po:PO-2402 SOD-04 Vendor vendor:V77 related to approver emp:E140Or install and run the packaged demo:
pip install veritas-reason
veritasreason-policy-demoThe same pattern applies to leave-policy violations (HRIS attendance), expense-report fraud (ledger + receipts), clinical protocol breaches (EHR + guidelines), or KYC/AML (transactions + watchlists). Define the SQL โ triple mapping in ingest_structured.py, write rules in rules/*.yaml, and ask in plain English. See veritas-reason/plan.md for a full walk-through.
๐ Interactive Graph Visualization
VeritasGraph includes an interactive 2D knowledge-graph explorer (PyVis) that visualizes entities and relationships in real time.

Feature | Description |
Query-aware subgraph | Shows only entities related to your query |
Community coloring | Nodes grouped by community membership |
Red highlight | Query-related entities shown in red |
Node sizing | Bigger nodes = more connections |
Interactive | Drag, zoom, hover for entity details |
Full graph explorer | View the entire knowledge graph |
โ๏ธ Provider Support (OpenAI-compatible)
VeritasGraph works with any OpenAI-compatible API โ mix and match cloud and local:
Provider | API Base | API Key | Example Model |
Ollama (default) |
|
|
|
OpenAI |
|
|
|
Groq |
|
|
|
Together AI |
| your-key |
|
LM Studio |
|
| (model loaded in LM Studio) |
Also supported: Azure OpenAI, OpenRouter, Anyscale, LocalAI, vLLM.
cd graphrag-ollama-config
cp settings_openai.yaml settings.yaml
cp .env.openai.example .env # edit with your provider settings
python -m graphrag.index --root . --config settings_openai.yaml
python app.pyโ ๏ธ Embeddings must match your index. If you indexed with
nomic-embed-text(768 dims), you must query with the same model โ switching embedding models requires re-indexing. Full details in OPENAI_COMPATIBLE_API.md.
๐ณ Deployment
Five-Minute Magic Onboarding (Docker)
Run a full stack (Ollama + Neo4j + Gradio) with one command:

Automated Knowledge Graph construction โ chunk documents into
TextUnits, extract(head, relation, tail)triplets, assemble nodes + edges in a graph DB (e.g. Neo4j).Hybrid retrieval engine โ vector search finds entry nodes, multi-hop traversal uncovers hidden relationships, pruning & re-ranking keeps the most relevant facts.
LoRA-tuned reasoning core โ a locally hosted, LoRA-tuned open model generates attributed answers with efficient fine-tuning for reasoning + attribution.
Attribution & provenance layer โ propagates source IDs, chunks, and graph nodes into a structured, traceable JSON output.
Hardware: 16+ CPU cores ยท 64GB+ RAM (128GB recommended) ยท NVIDIA GPU with 24GB+ VRAM (A100 / H100 / RTX 4090).
Software: Docker & Docker Compose ยท Python 3.10+ ยท NVIDIA Container Toolkit.
Copy .env.example โ .env and populate with environment-specific values.
Why VeritasGraph?
โ Fully on-premise & secure โ 100% control over your data and models.
โ Verifiable attribution โ every claim traces back to its source.
โ Advanced graph reasoning โ answers complex, multi-hop questions.
โ Hierarchical tree + graph โ PageIndex-style TOC navigation with graph flexibility.
โ Governed agents โ guardrails, memory, tools, and context budgeting wired together in Studio.
โ Open-source & sovereign โ MIT-licensed, no vendor lock-in.
Who is it for? Engineers building enterprise search, compliance assistants, research copilots, scientific literature explorers, and agent memory systems โ anywhere "the answer" depends on how facts connect, not just whether they appear near each other in a vector index.
