AI-native ontology engineering with 39 MCP tools backed by an in-memory Oxigraph triple store. Build, validate, query, and govern RDF/OWL ontologies using a generate-validate-iterate loop. Supports SPARQL querying, SHACL validation, OWL-RL reasoning, Terraform-style lifecycle management (plan/enforce/apply/monitor/drift), data ingestion from CSV/JSON/XML/XLSX/Parquet, clinical terminology crosswalks (ICD-10, SNOMED CT, MeSH), and ontology alignment with self-calibrating confidence.

Security audit

Not scanned yet. We audit npm-published capabilities for known advisories, install-time scripts and permission surface; this one has no npm package we can resolve, or has not reached the queue.

You searched for one. Check the rest of your stack:

npx tashan-cli doctor

Reads the config already on your machine and names what is dead, deprecated or running code at install time. No account, nothing uploaded.

Everything on this page is public evidence and free. What it cannot know is whether you run this — check your whole config, free, in the browser. tashan Pro adds the series behind each row and names a replacement for anything dying.

Already running this? Check your whole config — free, in your browser, nothing installed. Or npx tashan-cli doctor locally, which sends nothing at all.
