# 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](https://pypi.org/project/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.

## Prerequisites

- **Python:** 3.12 or higher
- **Package Manager:** [uv](https://docs.astral.sh/uv/). Install if needed:
  ```bash
  curl -LsSf https://astral.sh/uv/install.sh | sh
  ```

### Optional Dependencies

- **TA-Lib C Library:** Required for technical indicators. Follow [official installation instructions](https://ta-lib.org/install/).

## Installation

# Core features only
uvx investor-agent

# With technical indicators (requires TA-Lib)
uvx "investor-agent[ta]"
```

uv sync --group dev

# Set up your API key
export OPENAI_API_KEY="your-api-key"  # or ANTHROPIC_API_KEY, GEMINI_API_KEY, etc.

# Optional: Set custom model (defaults to openai:gpt-5-mini)
export MODEL_IDENTIFIER="your-preferred-model"

# Run the chat interface
python chat.py
```

For available model providers and identifiers, see the [pydantic-ai documentation](https://ai.pydantic.dev/models/).
