Works with Claude, ChatGPT, Cursor, and more

The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.

This connection provides 3 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.

Tax strategy used to be an educated guess.

Right now, figuring out where to put your retirement savings feels like a guessing game. You look at tax forms and account brochures, trying to figure out if you should prioritize the 401k match or dumping money into an HSA. You end up doing manual math in spreadsheets, constantly cross-referencing current rates against projected future rates—a process that's tedious, error-prone, and leaves you guessing about true tax savings.

With this MCP, your AI agent handles the heavy lifting. You provide the inputs, and it returns a clear strategy. It doesn't just tell you *what* to do; it tells you the most efficient order of funding accounts so you actually save money at every step.

determine_optimal_sequence

The key manual steps that disappear are the comparison charts and the marginal tax rate calculations. You don't have to spend hours comparing a handful of account options; the system weighs your current income against future needs automatically.

It’s precise. You get an actionable, prioritized checklist for funding your money. It makes complex financial planning feel like following directions.

What your AI can actually do with this

Figuring out the best way to fund retirement accounts can feel impossible because every decision—from which account you hit first to how much you contribute—affects your taxes years down the line. This MCP gives you specialized insight into tax arbitrage strategies. It analyzes your current income against projected future rates, telling you the most efficient order for funding accounts like 401k and HSA.

You can calculate exactly how much tax money you save by following a specific plan or project what your total portfolio balance will look like over decades. Because this is so complex, Vinkius hosts it as an MCP, letting your AI client connect directly to the engine without needing complicated setups.

Questions you might have

What should I use determine_optimal_sequence for? +

You use determine_optimal_sequence when you need to know the most tax-efficient order of operations. It weighs your current and projected tax brackets against all available accounts like 401k, HSA, and IRA.

How do I estimate my total savings with calculate_tax_savings? +

You use calculate_tax_savings to quantify the dollar value of your tax shield benefits. It gives you a solid number for annual or cumulative tax avoidance based on your plan.

Can I project my future wealth using project_wealth_growth? +

Yes, that's what project_wealth_growth does. You input your contribution amount and timeframe, and it forecasts the total size of your portfolio after decades.

Is determine_optimal_sequence better than using a financial advisor? +

It’s a powerful tool for immediate analysis. It models tax law mechanics instantly, giving you data to take to an advisor or use as a starting point yourself.

What specific inputs are required for `calculate_tax_savings` to run an accurate model? +

You must provide your current marginal tax rate, expected contribution amounts, and the account type (e.g., pre-tax vs. Roth). The MCP uses these variables to calculate the true tax shield benefit across different years.

If my income changes yearly, can `determine_optimal_sequence` handle fluctuating tax brackets? +

Yes, you don't have to assume a flat rate. You input projected tax scenarios for each year or decade. This allows the tool to build an optimal contribution sequence that adapts to anticipated changes.

Is the optimization strategy provided by `determine_optimal_sequence` limited only to US-based retirement accounts? +

This MCP is specialized for U.S. tax code, covering standard vehicles like 401k, IRA, and HSA. It cannot model international or foreign pension structures.

What are the recommended time limits when running `project_wealth_growth`? +

The tool works best projecting wealth over typical retirement timelines, usually 20 to 50 years. Keep inputs focused within this range for the most reliable forecast.

How does the optimizer decide which account to fund first? +

The engine follows a strict hierarchy: it always prioritizes Employer Match first, followed by HSA eligibility. Then, it uses determine_optimal_sequence to compare your current and future tax rates to decide between Traditional or Roth vehicles.

Can I use this for HSA planning? +

Yes. The tool checks your hasHsaEligibility and prioritizes HSA contributions due to their triple tax advantage.

What inputs do I need for wealth projection? +

For project_wealth_growth, you will need your annual contribution amount, years until retirement, expected return rate, and a breakdown of how much to allocate to each account.
