Time Series Quant Finance MCP Server

An MCP (Model Context Protocol) server built using FastMCP that calculates technical analysis indicators for financial stock tickers using yfinance and pandas-ta.

This server provides LLMs with access to real-time financial market data and quantitative analysis tools, enabling them to analyze stock trends, momentum, volatility, and key moving averages.

Features

• Automatic Baseline Trends: Always includes 50-day Simple Moving Average (SMA) and 200-day SMA to establish baseline trends.

• Multiple Technical Indicators: Support for:

  • RSI (Relative Strength Index)

  • MACD (Moving Average Convergence Divergence)

  • BBANDS (Bollinger Bands)

  • ATR (Average True Range)

  • SMA (Simple Moving Average with custom lengths)

  • EMA (Exponential Moving Average with custom lengths)

• Robust Multi-index Handling: Programmatically flattens yfinance multi-level indices to prevent Pandas crashes.

• JSON Output: Returns the last 5 trading days of historical and calculated data, cleaned and formatted for easy consumption by an LLM.

Installation & Setup

Prerequisites

• Python >= 3.12

• uv (recommended package manager) or standard pip

1. Clone & Install Dependencies

Using uv (recommended):

# Install dependencies using uv
uv sync

Or using standard pip and virtual environments:

# Create and activate a virtual environment
python3 -m venv .venv
source .venv/bin/activate

# Install dependencies
pip install -r requirements.txt

Running and Debugging

Running via FastMCP Dev Inspector

FastMCP includes a built-in development inspector that lets you interact with and test the server in a web UI.

# Using uv
uv run fastmcp dev server.py

# Or using standard python
python server.py dev

Alternatively, you can use the official MCP Inspector:

npx -y @modelcontextprotocol/inspector uv run server.py
