wren-engine

Wren Engine is an open context engine for AI agents that transforms business data into agent-usable context. It captures business definitions, metrics, relationships, and access rules, enabling agents to understand models and generate accurate queries. The engine supports MCP, HTTP APIs, and can be embedded into various agent workflows.

wren-engine sits in the Dev Tooling category, so it is usually better judged by workflow fit, deployment style, and team needs than by isolated features alone. Based on the available metadata, it leans most clearly toward Semantic modeling with MDL for business context. A representative use case is Natural language analytics with trusted business definitions. The listed license is Apache-2.0. GitHub stars are currently 660. Relevant tags include agent, agentic-ai.
