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 help users obtain:

Detailed ticker reports including company overview, news, key metrics, performance, dates, analyst recommendations, and upgrades/downgrades.
Options data highlighting high open interest.
Historical price trends for stocks.
Essential financial statements (income, balance sheet, cash flow).
Up-to-date institutional ownership and mutual fund holdings.
Earnings history and insider trading activity.
Current and historical CNN Fear & Greed Index data and trend analysis.
Technical indicator calculations (SMA, EMA, RSI, MACD, BBANDS).
Prompts related to core investment principles and portfolio construction strategies.

The server integrates with yfinance for market data retrieval and fetches Fear & Greed data from CNN. It automatically caches yfinance API responses for an hour in a local yfinance.cache file to improve performance and reduce redundant API calls.

Combine this with an MCP server for placing trades on a brokerage platform such as tasty-agent to place trades on tastytrade platform. Make sure to also enable web search functionality if you would like to incoporate latest news in your analysis.

Prerequisites

Python: 3.12 or higher

Package Manager: uv. Install if you haven't:

curl -LsSf https://astral.sh/uv/install.sh | sh

Optional: TA-Lib C Library

Required if you need the calculate_technical_indicator tool. Follow the official installation instructions for your operating system.

Installation

Quick Start (Run without Installing)

The easiest way to run the agent is using uvx, which fetches and runs the package without installing it globally or in a specific environment:

# Run with core features only
uvx investor-agent

If you need the calculate_technical_indicator tool (and have the prerequisite TA-Lib C Library installed), you can include the optional dependencies:

# Run with technical indicator features included
uvx "investor-agent[ta]"

Note: Using uvx "package[extra]" requires a recent version of uv (0.7.0 or later). Note: Using uvx with [ta] requires the TA-Lib C library to be properly installed and discoverable on your system beforehand.
