investor-agent: A Financial Analysis MCP Server

Overview

The investor-agent is a Model Context Protocol (MCP) server that provides comprehensive financial insights and analysis to Large Language Models. It leverages real-time market data, fundamental and technical analysis to deliver:

• Market Movers: Top gainers, losers, and most active stocks with support for different market sessions
• Ticker Analysis: Company overview, news, metrics, analyst recommendations, and upgrades/downgrades
• Options Data: Filtered options chains with customizable parameters
• Historical Data: Price trends and earnings history
• Financial Statements: Income, balance sheet, and cash flow statements
• Ownership Analysis: Institutional holders and insider trading activity
• Earnings Calendar: Upcoming earnings announcements with date filtering
• Market Sentiment: CNN Fear & Greed Index, Crypto Fear & Greed Index, and Google Trends sentiment analysis
• Technical Analysis: SMA, EMA, RSI, MACD, BBANDS indicators (optional)

The server integrates with yfinance for market data and automatically optimizes data volume for better performance.

Architecture & Performance

Robust Caching & Error Handling Strategy:

1. yfinance[nospam] → Built-in smart caching + rate limiting for Yahoo Finance API
2. hishel → HTTP response caching for external APIs (CNN, crypto, earnings data)
3. tenacity → Retry logic with exponential backoff for transient failures

This multi-layered approach ensures reliable data delivery while respecting API rate limits and minimizing redundant requests.
