Ask the question you have always wanted to ask.

Or pick one of ours. You will be talking to Claude wired into Precisian's Data Lake, about a model retail operation.

MCP is what gives an AI access to data. Without it, Claude answers in the dark: it knows nothing about your orders, your spend or your stock. Connecting is not a months-long project. It is pasting one credential.

START HERE
  1. Copy the MCP credentialIt is what gives Claude read access to the lake.
  2. Paste it into the chat below and sendIn the demo's message box, right below this. That gesture is what connects Claude to the lake.
  3. Ask anythingType your question or click one of the suggestions.

In your own operation it is the very same gesture. Your team pastes the MCP credential into Claude, into ChatGPT or into an agent of their own, and queries the company's data with the calculation in plain sight. No spreadsheet exports. Access is what you authorised, and every query is logged.

Simulation with fictional data. The model operation is a retailer with e-commerce and 28 stores; no number here belongs to a real client. Queries run on that demo base. In production it is Precisian's MCP server that answers, over your own lake.
