README

Claude + Teradata ClearScape Analytics via Model Context Protocol (MCP)


What Is This?

This project demonstrates how Claude AI can be connected directly to Teradata to enable:

  • 🔍 Natural language data exploration — Ask Claude about your data in plain English
  • 🤖 In-database ML — Run KMeans clustering inside Teradata via Claude, no data movement
  • 📊 Progressive segmentation — Show how richer features reveal richer customer segments
  • 🔗 MCP as a data engineering framework — A reusable pattern for AI + enterprise data

The Business Story

"We started with 50,000 customers and 2 years of transactions. By asking Claude natural language questions, we profiled our data, identified quality issues, and ran customer segmentation — all without writing a single line of SQL manually. Everything ran inside Teradata. No data left the platform."

Three Phases of Segmentation

Phase Features Used What It Reveals
1. Behavioral RFM (Recency, Frequency, Monetary) How customers transact
2. + Risk RFM + Credit Score Who is financially at-risk
3. + Demographics RFM + Risk + Age + Income Full customer identity

Each phase finds a different optimal number of clusters — proving that richer data = richer insight.

Quick Start

Prerequisites

1. Clone the repo

git clone https://github.com/YOUR_USERNAME/teradata-mcp-poc.git
cd teradata-mcp-poc

2. Install dependencies

pip install -r requirements.txt

3. Configure credentials

cp config.example.yaml config.yaml
# Edit config.yaml with your Teradata host, username, and password

4. Connect Claude Desktop to Teradata

Add this to your Claude Desktop config file:

  • Mac: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json
{
  "mcpServers": {
    "teradata": {
      "command": "python",
      "args": ["C:\\path\\to\\teradata-mcp-poc\\mcp\\server.py"]
    }
  }
}

Restart Claude Desktop — you'll see teradata appear in Settings → Connectors.

5. Talk to your data

Open Claude Desktop and ask:

List all my Teradata databases
Show me the tables in demo_user
Profile the transactions table
Check for data skew on the customer_demographics table
Run a data quality check on demo_user.credit_risk

6. Run the notebook

jupyter notebook notebooks/01_poc_walkthrough.ipynb

Example Conversations with Claude

Data exploration:

"Profile the transactions table and tell me if there are any data quality issues"

Segmentation:

"Run a KMeans experiment on segmentation_rfm_scaled using monetary_scaled, frequency_scaled, recency_scaled for k=2 to 8"

Performance:

"Check if the customer_demographics table has any skew issues and review its Primary Index"

Lineage:

"Find everything that references the transactions table"


Dataset

The PoC uses a synthetic customer dataset with:

  • 799,477 transactions across 50,000 customers (Jan 2023 – Dec 2024)
  • Customer demographics: age, income, employment years
  • Credit risk: credit score (400–849), loan exposure, late payments
  • Pre-built features: RFM aggregations, multiple scaled tables for clustering
