Built on the Model Context Protocol (MCP) for 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 planning used to mean endless tab switching and spreadsheets., Solved with Vinkius AI Gateway

Today, figuring out tax-loss harvesting requires hopping between rate tables, checking different country's regulatory calendars, and manually running loss/gain scenarios. You copy numbers from one spreadsheet into another, hoping you haven't mixed up US state law with EU guidelines.

With this MCP, the process is direct. Instead of juggling multiple documents, your agent handles the complexity. It delivers a single, actionable report showing exactly how much tax you avoid and what the net savings are.

The Tax Loss Harvesting Calculator gives you certainty.

You no longer have to manually confirm if your intended sale period violates a wash sale rule. The MCP checks this specific window, which is often the trickiest part of compliance.

Now, you get immediate confirmation on regulatory status and projected savings in one pass. It's about reliable, accurate data when filing taxes.

What your AI can actually do with this

Tax loss harvesting is complex, involving specific rules about timing and jurisdiction that change constantly. This connector provides specialized tools to calculate exactly how much tax you can avoid by strategically selling assets. You use it to determine avoided taxes and net savings after factoring in reinvestment costs. Need to know if a sale triggers a wash sale rule? It checks the compliance window for you, regardless of where you are located.

Plus, you can retrieve current capital gains rates based on your income band and location. When building out financial workflows with Vinkius, this MCP adds deep tax intelligence directly into your process, letting you focus on strategy instead of compliance rules.

Questions you might have

How does the Tax Loss Harvesting Calculator use `evaluate_harvesting_opportunity`? +

It calculates your potential tax benefits and net economic impact. You input your losses and fees, and it spits out the total avoided taxes minus any reinvestment friction cost.

What does `get_wash_sale_window` tell me? +

This tool determines the specific regulatory window for wash sale compliance. It tells you if a sale is allowed right now based on your chosen jurisdiction.

Do I need to use `retrieve_tax_rate_by_jurisdiction` first? +

Yes, always. You must confirm the correct capital gains rate for both your location and income band before calculating any tax savings or planning a harvest.

Can I check multiple countries in one go using Tax Loss Harvesting Calculator? +

The MCP is designed to handle comparisons. You can use the jurisdiction tools to compare rules between areas like the USA and Germany efficiently.

When calculating losses, how does `evaluate_harvesting_opportunity` account for transaction fees? +

The tool requires you to input any associated fees. It automatically factors these costs into the calculation, giving you the net savings figure after commissions or other friction costs.

If I check a country using `get_wash_sale_window` that is outside its supported regions, what happens? +

It returns an explicit error detailing unsupported geography. You must use the tool only for jurisdictions listed in its documentation; it won't guess or provide approximations.

Does `retrieve_tax_rate_by_jurisdiction` need my exact income figures to work? +

No, you just need your jurisdiction and an approximate income band. This is enough information for the tool to retrieve the applicable capital gains rate range.

What if I have a complex tax situation that crosses multiple state lines when running `evaluate_harvesting_opportunity`? +

The MCP handles single-jurisdiction calculations. For complicated, multi-state scenarios, you'll need to run separate calculations for each relevant jurisdiction and sum the results yourself.

How do I calculate my potential tax savings? +

Use the evaluate_harvesting_opportunity tool by providing your current positions, the applicable tax rate, and any reinvestment friction costs.

What is the wash sale rule window for the USA? +

For the USA, the get_wash_sale_window tool confirms a 30-day period surrounding the transaction where you must avoid repurchasing substantially identical securities.

Can I retrieve tax rates for European countries? +

Yes, use retrieve_tax_rate_by_jurisdiction to get the flat capital gains rate for supported EU nations.
