Rich metadata context engine for AI-driven data analytics

DataRaum Context Engine

A rich metadata context engine for AI-driven data analytics.

Traditional semantic layers tell BI tools "what things are called." DataRaum tells AI "what the data means, how it behaves, how it relates, and what you can compute from it."

The core insight: AI agents don't need tools to discover metadata at runtime. They need rich, pre-computed context delivered in a format optimized for LLM consumption.

Quick Start — MCP Server

The most common way to use DataRaum is as an MCP server inside Claude Desktop (or any MCP-compatible client).

# Install
pip install dataraum

# Or with uv
uv pip install dataraum

Add to your Claude Desktop config (claude_desktop_config.json):

{
  "mcpServers": {
    "dataraum": {
      "command": "dataraum-mcp"
    }
  }
}

Then in Claude Desktop:

Add the CSV files in /path/to/my/data and measure data quality

The server runs a 17-phase analysis pipeline and makes these tools available:

Tool	Description
begin_session	Start an investigation session with a contract
add_source	Register a data source (CSV, Parquet, JSON, or directory)
look	Explore data structure, relationships, and semantic metadata
measure	Measure entropy scores, readiness, and data quality
query	Natural language query against the data
run_sql	Execute SQL directly with export support
end_session	Archive workspace and end the session

Typical Workflow

add_source(name="accounting", path="/path/to/data")
  → begin_session(intent="explore data quality", contract="exploratory_analysis")
  → look()                    # Understand the data
  → measure()                 # Check quality scores and readiness
  → query("total revenue?")   # Ask questions
  → run_sql(sql="...", export_format="csv", export_name="report")
  → end_session(outcome="delivered")

Quick Start — CLI

# Run analysis pipeline (writes metadata.db + data.duckdb to ./pipeline_output)
dataraum run /path/to/data

# Inspect what was produced
dataraum dev context ./pipeline_output

See CLI Reference for all options.

What It Produces

DataRaum analyzes your data and generates:

• Statistical metadata — distributions, cardinality, null rates, patterns
• Semantic metadata — column roles, entity types, business terms (LLM-powered)
• Topological metadata — relationships, join paths, hierarchies
• Temporal metadata — granularity, gaps, seasonality, trends
• Quality metadata — rules, scores, anomalies
• Entropy scores — uncertainty quantification across all dimensions
• Ontological context — domain-specific interpretation (financial, marketing, etc.)

LLM Configuration

Semantic analysis requires an Anthropic API key:

export ANTHROPIC_API_KEY="sk-..."

Configure the LLM provider in config/llm/config.yaml. See Configuration for details.
