ralfbecher/orionbelt-analytics
Ontology-based MCP server that analyzes database schemas (PostgreSQL, Snowflake, ClickHouse, Dremio) and generates RDF/OWL ontologies with SQL mappings for fan-trap-free Text-to-SQL.
Implements GraphRAG for intelligent relationship discovery across up to 12 hops in database graphs, combined with ChromaDB vector embeddings for semantic similarity search, enabling LLMs to autonomously discover schema structure and create OBML semantic models. Operates as a FastMCP server with connection-scoped RDF stores, SPARQL 1.1 query support via Oxigraph, and R2RML mapping generation aligned to W3C standards for interoperable Text-to-SQL execution.
Available on PyPI.
