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.

The headache of manual water system design

Right now, sizing a hot water system means juggling multiple spreadsheets. You pull occupancy data into one sheet, check the fuel type in another, and then cross-reference plumbing codes to determine if your calculated flow rate even matches the recommended tank volume. It's slow, it’s complex, and you always worry about missing a critical variable.

With this MCP, those separate steps disappear. You tell your agent the variables—occupancy, use case, fuel—and get back three numbers: the required First Hour Rating (FHR), the minimum tank capacity in gallons, and an efficiency comparison chart. It’s all done automatically.

Calculating with `get_efficiency_comparison`

Today, determining if a gas unit beats a heat pump requires logging into three different manufacturer sites and comparing EF specs manually. This is tedious work that eats up hours of your week.

Now you just run `get_efficiency_comparison`. It gives you the side-by-side benchmark instantly. You know exactly where the energy savings are without opening a single new tab.

What your AI can actually do with this

When you're designing a new building or updating an existing one, getting the right size water heater system is mission-critical. Too small, and the whole place runs out of hot water during peak hours. Too big, and the client just hates paying for unnecessary infrastructure. This MCP gives you precise calculations for sizing systems based on occupant demand and fuel technology.

It calculates the necessary First Hour Rating (FHR) using factors like how many people are in the building and if it's commercial or residential use. You can then determine the minimum tank volume needed in gallons, which accounts for usage patterns. Plus, you get a side-by-side view comparing energy factor benchmarks across gas, electric, and heat pump setups.

This is essential data that plumbing professionals rely on to design efficient hot water delivery systems. If you manage your technical catalogs through Vinkius, this MCP plugs directly into your existing workflow.

Questions you might have

How do I use calculate_fhr_requirement to start my design? +

You need to input the building's usage type, total occupant count, and if it’s residential or commercial. The tool outputs the necessary First Hour Rating (FHR) needed for peak demand.

Does calculate_tank_capacity account for fuel type? +

It focuses on occupancy patterns to recommend minimum volume in gallons. However, you should use get_efficiency_comparison alongside it to ensure the chosen fuel supports that capacity efficiently.

What is the best way to compare gas vs electric heaters? +

Just run get_efficiency_comparison. It gives a clear, comparative view of the Energy Factor (EF) for all three technologies you list in your prompt.

Can I use calculate_fhr_requirement and calculate_tank_capacity together? +

Yes. First, run calculate_fhr_requirement to establish peak flow demand. Then, feed that data into calculate_tank_capacity to ensure the tank volume matches your required throughput.

Does calculate_tank_capacity require me to input local building codes? +

Yes, it is best practice to include your specific regional plumbing code requirements. The minimum tank volume calculation depends heavily on whether you are designing for residential or commercial standards.

What happens if I use calculate_fhr_requirement with extremely high usage metrics? +

The tool will return the highest possible FHR rating allowed by code. If inputs exceed physical limits, it flags an error and suggests increasing system capacity or re-evaluating demand sources.

Should I run get_efficiency_comparison before using calculate_fhr_requirement? +

No, you can execute them separately. Use the efficiency comparison first to select your ideal technology, then feed that choice into calculate_fhr_requirement for accurate sizing.

Does get_efficiency_comparison factor in regional climate variations? +

The tool provides general national Energy Factor benchmarks. For areas with extreme temperature swings, you must manually adjust the resulting EF values based on local usage patterns.
