Auto Ontology is an open-source project on GitHub in the Developer category, listed by Mindket. It is free. This is version 1, last updated on 2026-11-05. Install it from GitHub as its README says. Get Mindket’s setup notes on your Mindket account, as a zip. Made by NVIDIA ## About ### What it is Auto Ontology is a library that builds a semantic layer from enterprise metadata to provide agents with trusted business meaning. It generates ontologies, reconciles definitions across systems, and exposes these to agents through MCP, CLI, and API. ### Who it suits It is designed for developers who need to ground their agents in certified business logic and metadata. ### Where to use it This tool functions through a web interface, CLI, REST API, or as an MCP server. ### How to set it up You need Docker with Compose v2, the uv package manager, and an NVIDIA API key from the NVIDIA API catalog. 1. Clone the repository and create your .env file. 2. Set your API key and internal passwords in the .env file. 3. Start the database service and run the seed script to load sample data. 4. Build and launch the stack using Docker Compose. 5. Open the web interface, sign in, and enable semantic compilation in the settings. ```bash docker compose up -d --build ``` ### How to use it You interact with the system by asking questions in the web chat, through the REST API, or by using MCP tools in compatible agents. ### Example The agent returns the answer, the generated SQL code, and the steps it took to reach that result. ### For newcomers and experts For those new to this, the system acts as a bridge that teaches your AI company-specific terms and data relationships. Experts can use the system to build knowledge graphs, validate generated queries against certified definitions, and expose these through an agent harness. ### Good to know - Supports ten database engines including PostgreSQL, MySQL, Databricks, and Snowflake. - Requires configuration of separate model roles for reasoning, entity extraction, and embeddings. - Does not accept external code contributions. - License: Apache License 2.0. ## README ````markdown # Auto Ontology Builds and manages semantic, graph-based knowledge layers from enterprise metadata to ensure reliable AI agent interactions.
