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.

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.
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.
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.
01-03
3 capabilities in this set.
Part of 3 available through Thermal Mass Estimator.
- 01
Estimate thermal behavior
This capability estimates the thermal lag and amplitude damping factor for a specific wall layer.
- 02
Calculate u value
Use this capability to calculate the thermal transmittance, or U-value, for a single material layer.
- 03
Get material properties
This capability retrieves fundamental thermal properties like conductivity and density for building materials.
Real work
What teams actually run
Envelope Design
Calculate how a specific wall thickness will impact the thermal transmittance of a building.
Thermal Mass Analysis
Predict the time delay and temperature damping for heavy materials like concrete.
Material Comparison
Compare the thermal properties of different materials to optimize energy efficiency.
Climate Response Modeling
Estimate how much a structure will dampen external temperature swings.
Automate a task
Put Thermal Mass Estimator 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
Thermal Mass Estimator 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.

Le ChatBuilding your own app? The connector is yours to use.
You don't need a client to put Thermal Mass Estimator 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.

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 Thermal Mass Estimator, so you can see the experience inside your AI.
It does not authenticate your account with Thermal Mass Estimator. 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 Thermal Mass Estimator owners hand off.
This MCP is designed for professionals working in building science and sustainable construction.
- 01
Building Scientists
They hand off material property lookups and thermal behavior modeling to their agent.
- 02
Architects
They use the capability to check how different wall thicknesses affect thermal performance.
- 03
Energy Consultants
They rely on U-value calculations to verify insulation and envelope efficiency.
FAQ
Questions Thermal Mass Estimator owners ask.
- 01
What can this MCP calculate?
It calculates thermal lag, amplitude damping, and U-values for building materials and wall layers.
- 02
Which materials are supported?
The capability can retrieve properties for common building materials like brick and concrete.
- 03
How do I use this with Claude?
You connect to the Vinkius hosted MCP once, and then your agent can call the capabilities directly in your chat.
- 04
Does it provide material density?
Yes, the get_material_properties capability provides density, conductivity, and specific heat.
- 05
Can I calculate U-values for multiple layers?
The calculate_u_value capability is designed for a single layer of material at a time.
- 06
What materials are supported?
The server currently supports brick, concrete, wood, and drywall.
- 07
How is the U-value calculated?
The U-value is calculated as the ratio of the material's thermal conductivity to its thickness in meters.
- 08
What does thermal lag represent?
Thermal lag represents the time interval between peak external temperature and peak internal temperature.
