◈ Quick Start

Get up and running in under 2 minutes:

Prerequisites: You must have QuantConnect credentials (User ID and API Token) before running the server. The server will not function without proper authentication. See Authentication section for details on obtaining these credentials.

Install with uvx (Recommended)

One-Click Claude Desktop Install (Recommended)

1. Download: Grab the latest quantconnect-mcp.dxt from the “Releases” page

2. Install: Double-click the file – Claude Desktop opens and prompts you to Install

3. Configure: In Claude Desktop → Settings → Extensions → QuantConnect MCP, paste your user ID and API token

4. Use it: Start a new Claude chat and call any QuantConnect tool

Why DXT?

Desktop Extensions (.dxt) bundle the server, dependencies, and manifest so users go from download → working MCP in one click – no terminal, no JSON editing, no version conflicts.

2. Set Up QuantConnect Credentials (Required)

The server requires these environment variables to function properly:

3. Launch the Server

4. Interact with Natural Language

Instead of calling tools programmatically, you use natural language with a connected AI client (like Claude, a GPT, or any other MCP-compatible interface).

"Add GOOGL, AMZN, and MSFT, then run a PCA analysis on them for 2023."

◈ Natural Language Examples

This MCP server is designed to be used with natural language. Below are examples of how you can instruct an AI assistant to perform complex financial analysis tasks.

Factor‑Driven Portfolio Construction Pipeline

“Build a global equity long/short portfolio for 2025:

1. Pull the constituents of QQQ, SPY, and EEM as of 2024‑12‑31 (survivor‑bias free).

2. For each symbol, calculate Fama‑French 5‑factor and quality‑minus‑junk loadings using daily data 2022‑01‑01 → 2024‑12‑31.

3. Rank stocks into terciles on value (B/M) and momentum (12‑1); go long top tercile, short bottom, beta‑neutral to the S&P 500.

4. Within each book, apply Hierarchical Risk Parity (HRP) for position sizing, capped at 5 % gross exposure per leg.

5. Target annualised ex‑ante volatility ≤ 10 %; solve with CVaR minimisation under a 95 % confidence level.

6. Benchmark against MSCI World; report annualised return, vol, Sharpe, Sortino, max DD, hit‑rate, turnover for the period 2023‑01‑01 → 2024‑12‑31.

7. Export the optimal weights and full tear‑sheet as pdf + csv.

8. Schedule a monthly rebalance job and push signals to the live trading endpoint.”

Robust Statistical‑Arbitrage Workflow

“Test and refine a pairs‑trading idea: • Universe: US Staples sector, market cap > $5 B, price > $10. • Data: 15‑minute bars, 2023‑01‑02 → 2025‑06‑30. • Step 1 – For all pairs, calculate rolling 60‑day distance correlation; keep pairs with dCor ≥ 0.80. • Step 2 – Run Johansen cointegration (lag = 2) on the survivors; retain pairs with trace‑stat < 5 % critical value. • Step 3 – For each cointegrated pair:    – Estimate half‑life of mean‑reversion; discard if > 7 days.    – Compute Hurst exponent; require H < 0.4. • Step 4 – Simulate a Bayesian Kalman‑filter spread to allow time‑varying hedge ratios. • Entry: z‑score crosses ±2 (two‑bar confirmation); Exit: z = 0 or t_max = 3 × half‑life. • Risk: cap pair notional at 3 % NAV, portfolio gross leverage ≤ 3 ×, stop‑loss at z = 4. • Output: trade log, PnL attribution, bootstrapped p‑value of alpha, and Likelihood‑Ratio test for regime shifts.”

Automated Project, Backtest & Hyper‑Parameter Sweep

“Spin up an experiment suite in QuantConnect:

1. Create project ‘DynamicPairs_Kalman’ (Python).

2. Add files:    • alpha.py – signal generation (placeholder)    • risk.py – custom position sizing    • config.yaml – parameter grid:        yaml        entry_z: [1.5, 2.0, 2.5]        lookback: [30, 60, 90]        hedge: ['OLS', 'Kalman']        

3. Trigger a parameter‑sweep backtest labelled ‘GridSearch‑v1’ using in‑sample 2022‑23.

4. When jobs finish, rank runs by Information Ratio and max DD < 10 %; persist top‑3 configs.

5. Automatically launch out‑of‑sample backtests 2024‑YTD for the winners.

6. Produce an executive summary: tables + charts (equity curve, rolling Sharpe, exposure histogram).

7. Package the best model as a Docker image, push to registry, and deploy to the live‑trading cluster with a kill‑switch if 1‑day loss > 3 σ.”

Statistical Analysis Workflow

"Are Coca-Cola (KO) and Pepsi (PEP) cointegrated? Run the test for the period from 2023 to 2024. If they are, analyze their mean-reversion properties with a 20-day lookback."

Project and Backtest Management

"I need to manage my QuantConnect projects. First, create a new Python project named 'My_Awesome_Strategy'. Then, create a file inside it called 'main.py' and add this code: ...your algorithm code here.... After that, compile it and run a backtest named 'Initial Run'. When it's done, show me the performance results."

Live Trading Deployment & Monitoring

"Deploy my compiled algorithm to live trading using Interactive Brokers paper trading. Set up the brokerage configuration with my IB credentials, then monitor the runtime statistics including equity, holdings, and net profit. If the algorithm shows a loss greater than 5%, automatically liquidate all positions and stop the algorithm."

Live Algorithm Management

"Show me all my currently running live algorithms. For each one, display the runtime statistics, recent logs from the last 100 lines, and current portfolio holdings. If any algorithm has been running for more than 24 hours without trades, flag it for review."
