Open semantic layer that grounds AI agents in your data

Auto-Ontology builds a reviewed context layer over your databases so AI agents query the right data. It drafts an ontology from schemas, profiles and query history (business terms, relationships, reusable SQL), lets people certify it, then turns questions into checked SQL and returns the answer with its query and reasoning, or says when the data can't answer. Ten engines, from Postgres to Snowflake. Web UI, REST API and MCP server. Apache-2.0.

    Text-to-SQL demos look great until the agent picks the wrong table. Auto-Ontology adds the missing step: a semantic layer humans review before agents rely on it, and an honest 'can't answer' when the data isn't there. Worth a look if you put agents on company data.
