VingolfThe Hall of Living Knowledge
Built for serious AI engineers
Not another GPT wrapper. Vingolf combines GraphRAG retrieval, fine-tuned extraction models, and type-safe agent orchestration into a cohesive intelligence platform.
The Records
Neo4j graph + Qdrant vectors. Query by similarity, traverse by relationship.
The Guests
PydanticAI agents with structured outputs. CrewAI for parallel research.
The Gatekeeper
Custom RBAC with scoped API keys. SHA-256 hashing. Rate limiting.
- FastAPI Gateway
- Cloud Run / GKE
- MCP Server
- Neo4j (Graph Floor)
- Qdrant (Vector Floor)
- Embeddings
- Researcher Agent
- Analyst Agent
- Synthesizer Agent
What lives in The Hall
GraphRAG Retrieval
Vector similarity finds relevant nodes. Graph traversal expands context with 2-hop relationships.
Fine-tuned Extraction
Llama 3.2 trained with Unsloth converts unstructured text into Cypher triples.
Type-safe Agents
PydanticAI ensures structured outputs. No more parsing JSON from prompts.
MCP Integration
Expose The Hall as tools for Claude Desktop, Cursor, or any MCP client.
Logfire Observability
Deep traces of every LLM call, agent decision, and retrieval operation.
Multi-tenant Ready
Scoped API keys, rate limiting, and usage tracking per organization.
