What standards does this MCP use?

This MCP uses simplified Manual J standards for thermal load calculations.

Can I use this with Claude or Cursor?

Yes, you can connect this MCP to any MCP-compatible client including Claude, Cursor, and Windsurf.

What units of measurement are provided?

The capability provides heating loads in BTU/h and cooling loads in both BTU/h and Tons.

How do I check if an AC unit is big enough?

You use the validate_equipment_capacity capability to compare a unit's rated capacity against your calculated load.

Does it account for people in the room?

Yes, the calculation includes internal heat gains from occupancy.

What does the calculate_heating_demand capability do?

It determines the total heating capacity required (in BTU/h) by considering the conditioned area, insulation level, and IECC climate zone.

How can I check if my HVAC unit is large enough?

Use the validate_equipment_capacity capability by providing the required heating load, required cooling load, and the nominal BTU capacity of your unit.

Does the cooling calculation include solar gain?

Yes, the calculate_cooling_demand capability accounts for solar radiation through window areas in all four cardinal directions.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through HVAC Load Calculator.

01
Calculate cooling demand
This capability calculates the cooling load in BTU/h and Tons. It handles the math for heat gain to determine how much cooling capacity a space needs.
02
Validate equipment capacity
This capability checks if a specific HVAC unit's rated capacity is enough for your calculated loads. It tells you if a unit is underpowered for the space.
03
Calculate heating demand
This capability determines the heating load in BTU/h. It calculates the heat loss required to maintain temperature in a residential space.

Real work

What teams actually run

Residential Load Estimation

Calculate the heating and cooling needs for a new home build based on square footage and insulation.

Equipment Validation

Verify if a customer's existing HVAC unit is sufficient for the calculated thermal load.

Solar Gain Assessment

Determine how window orientation affects the cooling load of a specific room.

Climate Zone Planning

Adjust heating demand calculations based on specific climate zone requirements.

Automate a task

Put HVAC Load Calculator to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

HVAC Load Calculator works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put HVAC Load Calculator to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of HVAC Load Calculator, so you can see the experience inside your AI.

It does not authenticate your account with HVAC Load Calculator. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
