Pull your quants numbers directly with Claude / ChatGPT in Excel (with MCP).

Published: March 7, 2026

Ask in plain English: "Pull all stats for Apple, Google, Microsoft past 10 years".

Get back 81 metrics - returns, sharpe, sortino, drawdowns - the whole bucket load.

Powered by Ran Aroussi's (creator of yfinance python library) QuantStats library.

Works with Claude in Excel, ChatGPT in Excel, Claude Desktop, Cursor, n8n, or any MCP client.

MCP Server URL: qrep-api.tigzig.com/mcp

The server is free to use (rate limits apply). Just add that URL as custom connector and you are set.

This is the public version. No API key. No auth. For production use, always use OAuth / SSO (see links below).

At the same time, my standard MCP advice still stands - don't connect to unknown MCP servers blind. Use servers from reputed providers, or ones you deploy yourself. If you'd like to implement, easiest way - paste this message to your AI Coder. It knows what to do.

Full source code is open. Single Python file. Clone it, inspect it, deploy your own.

Web version of QREP: qrep.tigzig.com
