Canner/wren-engine
🤖 The Semantic Engine for Model Context Protocol(MCP) Clients and AI Agents 🔥
Provides semantic modeling through MDL (Modeling Definition Language) to capture business definitions, metrics, relationships, and governance rules that agents can reason over—moving beyond raw schema discovery. Built as an MCP server with connectors to 15+ data sources (Snowflake, BigQuery, PostgreSQL, DuckDB, etc.) and designed for embedding in agent workflows, Claude Desktop, and developer IDEs. Uses Apache DataFusion for query planning and execution, enabling agents to translate natural language into governed, contextualized data access rather than ad hoc SQL generation.
