About WrenAI

WrenAI is an MCP server in the Other category: ⚡️ GenBI (Generative BI) queries any database in natural language, generates accurate SQL (Text-to-SQL), charts (Text-to-Chart), and AI-powered business intelligence in seconds.

Install

From source
git clone https://github.com/Canner/WrenAI

This server has no ConduID identity, so agent calls to it are not receipted. Pin the version you install and review the source before granting it credentials.

README

📣 2026-05-07 — Wren Engine has merged into this repo under core/. The previous Canner/wren-engine repo is archived. The previous WrenAI GenBI app is preserved on the legacy/v1 branch (tag v1-final). Read the announcement →

Why WrenAI?

AI agents fail on business data not because they can't write SQL — they fail because they don't know what your warehouse means. Overlapping tables, inconsistent naming, metric definitions scattered across dashboards and SQL files: an LLM with raw database access guesses just as badly as a new hire on day one.

WrenAI is the open context layer that fills that gap. You model your business in MDL (Modeling Definition Language) — entities, relationships, calculations, governed access patterns — and any agent (Claude, Cursor, ChatGPT, internal copilots, customer-facing apps) queries through the same layer your analysts already use.

A Rust engine powered by Apache DataFusion translates the modeled SQL and runs it against 20+ data sources (PostgreSQL, BigQuery, Snowflake, Spark, etc.). Use it as a Python SDK, a CLI, a WASM module in the browser, or as building blocks for agent skills.

Quick start

The fastest path is to let an AI coding agent (Claude Code, Cursor, Aider, etc.) drive the install:

# Install WrenAI skills into your AI agent
npx skills add Canner/WrenAI --skill '*'

Start a new agent session and ask:

Use the wren-onboarding skill to install and set up Wren AI Core.

The wren-onboarding skill walks the agent through environment checks, package install, project scaffolding, the first data source connection, and a first query.

Full CLI guide and manual install steps: core/wren/README.md. Installable extras for each connector are listed there.
