Windsurf & the MCP Server

The `calculate_roas` tool gives you a weighted average of your ad performance using just media spend and source revenue figures. It provides an accurate, immediate picture of which channels are actually making money for you. You can then chain that into a full analysis. For instance, run the `get_target_benchmark` to see what similar businesses aim for. This lets you compare your real-time data against industry norms without lifting a finger.

Figure Out Break-Even Points

Need to know where you stand financially? The `calculate_break_even_roas` tool determines the minimum ROAS required just to cover costs, based on your contribution margin. It pinpoints your break-even point so you don't waste capital. This is critical when setting a budget. You can immediately tell if your current spending trajectory is safe or if you're heading for losses. The MCP Server handles all the math in a zero-trust sandbox, keeping your keys safe.

Multi-Step Ad Budgeting

You don't have to prompt Windsurf for every step. Set a goal—say, 'Maximize ROAS while staying profitable.' The agent can then plan and execute the sequence itself. It will first run `calculate_break_even_roas`, then feed that result into `calculate_roas` for optimization. It's designed to handle multi-step finance tasks autonomously. Windsurf reads the context, figures out the necessary tools, runs them, and shows you the final answer without stopping to ask if you want to proceed.
