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.

Curated set · 3 capabilities

We ship only the actions that matter.

Capability set01 / 01

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.

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 3 capabilities arrive ready to run.

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.

Who it's for

Built for the work HVAC Load Calculator owners hand off.

This MCP is built for professionals working in residential HVAC design and thermal analysis.

  • 01

    HVAC Technicians

    They hand off room measurements and insulation data to get quick capacity estimates.

  • 02

    Residential Designers

    They use the capability to verify that proposed HVAC systems match the thermal needs of a room.

  • 03

    Building Inspectors

    They use the calculations to check if installed equipment meets the required load standards.

FAQ

Questions HVAC Load Calculator owners ask.

  • 01

    What principles does this MCP use for calculations?

    The MCP uses simplified Manual J principles to estimate residential thermal loads.

  • 02

    Can I use this with Claude or Cursor?

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

  • 03

    What data do I need to provide for a load calculation?

    You need to provide room dimensions, insulation quality, window orientation, and climate zone information.

  • 04

    Does it calculate both heating and cooling?

    Yes, it has specific capabilities to calculate both cooling loads and heating loads.

  • 05

    How do I know if my input data is correct?

    You can use the validate_room_configuration capability to ensure your dimensions and environmental factors are logically consistent.

  • 06

    How accurate are these calculations?

    The calculations use simplified Manual J principles to provide reliable residential estimates based on standard thermal resistance and climate zone data.

  • 07

    What is the purpose of the validation capability?

    The validate_room_configuration capability ensures that your room dimensions and window counts are logically consistent before you perform any load calculations.

  • 08

    Can I account for different insulation qualities?

    Yes, you can specify insulation as poor, average, or good to adjust the thermal load requirements accordingly.
