Run Both Credit Methods

The IRS gives you two ways to calculate your R&D credit: the Regular method and the Alternative Simplified Credit (ASC) method. Most people just pick one and stick with it, often leaving money on the table. This MCP lets you calculate both. You can run the numbers for the ASC method with `calculate_asc_method_credit` and compare it directly against the Regular method using `calculate_regular_method_credit`. The math doesn't lie.

Automated Strategy with Windsurf

Here's the thing. You don't need to run those calculations one by one. Just tell Windsurf's Cascade, 'Find my best R&D tax strategy for these expenses.' That's it. Cascade will automatically call the necessary tools, compare the results, and use `recommend_optimal_tax_strategy` to tell you which method saves you more money. You get the final answer, not a list of intermediate steps.

From Calculation to Code

Getting the number is just the first step. You need to document it, maybe build it into an internal dashboard or a report. Windsurf makes this part easy. Once Cascade determines the optimal credit, you can immediately instruct it to use that output. For example: 'Create a new React component that displays this tax credit amount.' Windsurf will generate the code, pulling the data directly from this MCP's output.

Common questions about R&D Tax Credit Calculator MCP in Windsurf

You give Cascade a high-level goal, like 'calculate the best R&D tax credit for my Q3 expenses.' Cascade automatically chains the tools from this MCP to compare the Regular and ASC methods and gives you the single best strategy. You don't have to prompt each step.

Yes, that's exactly what it's for. This R&D Tax Credit Calculator has separate tools for both methods. Better yet, you can just ask Windsurf to recommend the optimal strategy, and it will run the comparison for you automatically.

No. You can add it with one click from the MCP Marketplace inside Windsurf. Or, you can add the server URL manually in your settings. Cascade discovers the tools instantly.

You can provide qualified research expenses, including wages for qualified services, costs for supplies used in research, and amounts paid for contract research. The tools use these inputs to determine your credit.

Your expense data is sent to the MCP for the calculation but is not stored. The connection is encrypted, and Vinkius's infrastructure ensures that your financial inputs are only used for the transaction and then discarded.
