Auto Ontology MCP Overview

auto-ontology-mcp brings NVIDIA Auto Ontology concepts to MCP clients for querying databases and managing a personal knowledge base. It lets the client model business terms, inspect relationships, validate SQL, and run read-only queries against local SQLite files. Documents can be converted into stored facts, linked concepts, searchable passages, and source references while originals remain in an Obsidian vault. Reach for it when an agent needs grounded analytical answers or traceable notes without configuring a separate LLM API key.

Primary Use Cases for Auto Ontology MCP:
  • Validate agent-generated SQL against reviewed joins and stored values
  • Answer business questions from a locally modeled database
  • Store document facts, concepts, passages, and source references
  • Search saved notes and export them as an Obsidian knowledge base
