AI Data Analyst

A data distribution platform for AI analytical systems. It pulls data from configured sources, converts it to Parquet format, and distributes it to analysts who query it locally using Claude Code and DuckDB.

How It Works

flowchart TB
    subgraph Sources["Data Sources"]
        A[(Keboola)]
        B[(CSV Files)]
        C[(BigQuery / Snowflake)]
        style C stroke-dasharray: 5 5
    end

    subgraph Broker["Data Broker Server"]
        D[Source Adapter]
        E[Parquet Converter]
        D --> E
    end

    subgraph Analyst["Analyst Machine"]
        F[Parquet Files]
        G[(DuckDB)]
        H((Claude Code))
        F --> G
        G --> H
    end

    A --> D
    B --> D
    C -.->|planned| D
    E -->|rsync over SSH| F

1. The server fetches data from a configured source using the appropriate adapter.
2. Raw data is converted to typed, columnar Parquet files.
3. Analysts sync Parquet files to their machines over SSH (rsync).
4. Claude Code queries the local DuckDB database and returns results with insights.

Features

• Pluggable data sources -- adapter interface supporting Keboola out of the box, CSV import, and extensible to BigQuery, Snowflake, and others.
• Automatic Parquet conversion -- source data is converted to typed, partitioned Parquet files for efficient local querying.
• SSH-based distribution -- analysts sync data securely via rsync; no cloud credentials leave the server.
• Claude Code as analyst interface -- natural language queries against DuckDB, powered by Claude.
• Claude Code as installer -- the CLAUDE.md file guides Claude Code through automated project setup for new analysts.
• Self-service webapp -- web UI for user onboarding, SSH key management, sync settings, and data catalog browsing.
• Corporate Memory -- shared knowledge base that aggregates analyst insights and distributes approved rules back to the team.
• Configurable per-instance -- a single config/instance.yaml controls branding, authentication, data source, user mapping, and more.
• Access control -- role-based permissions with standard analyst, privileged analyst, and admin tiers.

Quick Start

See docs/QUICKSTART.md for full setup instructions.

The short version:

# 1. Clone the repository
git clone https://github.com/your-org/ai-data-analyst.git
cd ai-data-analyst

# 2. Copy and edit configuration
cp config/instance.yaml.example config/instance.yaml
cp config/data_description.md.example config/data_description.md
# Edit both files for your environment

# 3. Deploy the server
# See docs/DEPLOYMENT.md for detailed server setup

# 4. Analysts connect via the webapp and sync data
bash server/scripts/sync_data.sh

Supported Data Sources

Adapter	Status	Description
Keboola Storage	Available	Pulls tables via the Keboola Storage API
CSV	Planned	Imports local or mounted CSV files
BigQuery	Planned	Google BigQuery adapter
Snowflake	Planned	Snowflake adapter

Adding a new adapter means implementing the DataSource interface in src/adapters/ and setting data_source.type in config/instance.yaml. See src/adapters/base.py for the contract.

Using with Claude Code

Once data is synced, open Claude Code in the project directory and ask questions in natural language:

What are the top 10 customers by revenue this quarter?

Show me the trend in support ticket volume over the last 6 months.

Claude Code will connect to the local DuckDB database, write and execute SQL, and return results with analysis.
