QuantConnect

Exposes QuantConnect project creation as an MCP tool that LLMs can invoke directly, allowing Claude or o3 Pro to programmatically scaffold new algorithmic trading projects with boilerplate code, asset classes, and data feeds pre-configured. The MCP server translates natural language intent (e.g., 'create a momentum strategy for SPY') into QuantConnect API calls that initialize project structure, set resolution/universe parameters, and wire up data subscriptions without manual UI interaction.

Allows LLMs to submit strategy code and parameter ranges to QuantConnect's backtesting engine via MCP, receiving backtest results (Sharpe ratio, max drawdown, returns) that feed back into LLM reasoning loops for iterative optimization. The server handles code submission, job queuing, result polling, and JSON parsing of backtest metrics, enabling the LLM to autonomously evaluate strategy variants without manual result inspection.

Enables LLMs to deploy backtested strategies to QuantConnect's live trading environment by pushing strategy code, configuring live parameters (broker, account, position sizing), and triggering execution via MCP tools. The server handles code validation, live algorithm instantiation, and order routing setup, allowing autonomous agents to move from backtest → live trading without manual deployment steps.

Exposes live portfolio state (positions, P&L, Greeks for options, margin utilization) as MCP tools that LLMs can query to make real-time trading decisions. The server polls QuantConnect's live trading API and caches portfolio snapshots, allowing LLMs to reason about current market exposure, hedge requirements, and rebalancing needs without manual dashboard inspection.

Analyzes submitted strategy code for performance bottlenecks, risk violations, and optimization opportunities using static analysis and backtest metrics. The MCP server parses Python code, identifies common anti-patterns (e.g., look-ahead bias, excessive rebalancing), and suggests refactorings that improve Sharpe ratio or reduce drawdown based on historical performance data.

Allows LLMs to compose portfolios from multiple backtested strategies, allocate capital across them, and trigger rebalancing based on performance drift or market conditions. The MCP server manages strategy weights, tracks composite portfolio metrics, and executes rebalancing orders across all deployed strategies simultaneously, enabling autonomous multi-strategy portfolio management.

Provides LLMs with access to historical backtest results, equity curves, and trade logs for strategies, enabling post-hoc analysis and comparison. The MCP server queries QuantConnect's backtest archive, parses results, and surfaces key metrics (Sharpe, drawdown, trade statistics) that LLMs can use to reason about strategy performance across different time periods or market conditions.

Enforces user-defined risk constraints (max drawdown, max leverage, sector concentration limits) on live trading algorithms by intercepting orders and rejecting those that violate thresholds. The MCP server maintains a risk model that tracks current exposure, calculates constraint violations, and provides LLMs with real-time feedback on whether proposed trades are allowed.

Enables LLMs to define parameter search spaces (e.g., moving average windows, momentum thresholds) and automatically generate and backtest strategy variants across the grid. The MCP server orchestrates parallel backtest submissions, collects results, and ranks strategies by performance metrics, allowing LLMs to discover optimal parameters without manual iteration.
