In simple English
This tool lets you talk to your AI assistant about the stock market. It pulls live prices and historical charts from Yahoo Finance without needing an API key. You can track your personal stock portfolio and watchlists in a local database. It also runs backtests to see how trading strategies performed in the past. The core features cost nothing to run on your own computer.
What it is
MaverickMCP is a Model Context Protocol (a standard that lets an AI assistant call external tools) server written in Python. It provides dozens of tools for stock data, technical indicators, screening, portfolio risk, and optional backtesting or web research.
