How to choose
Match the tool to your core workload: trading engines like Lean or StockSharp for quant work, unity-mcp for game dev, or OfficeCLI for document automation. Check language support first—only Lean and StockSharp explicitly highlight C# alongside other languages. Watch for narrow use cases such as game-specific bots or media indexers that may not generalize. Avoid tools with very low engagement unless they solve an exact niche problem you face.
