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

01-03

3 capabilities in this set.

Part of 3 available through Concrete Calculator.

  1. 01

    Calculate rebar

    This capability calculates the total weight and length of steel reinforcement you need. It uses your specified spacing and bar diameter to get the math right.

  2. 02

    Calculate volume

    This capability determines the total concrete volume required for your project. You can include a customizable waste safety margin to account for spillage or uneven subgrades.

  3. 03

    Estimate materials

    This capability calculates the quantity of bags or truckloads required for a pour. It also provides the specific weights of cement, sand, gravel, and water for on-site mixing.

Real work

What teams actually run

01

Slab Foundation Planning

Calculate the exact volume and rebar weight for a new residential slab.

02

On-site Batching

Get the weight of raw materials like sand and gravel for mixing concrete by hand.

03

Truckload Scheduling

Determine if a job requires multiple truckloads or just a few bags of pre-mix.

04

Reinforcement Verification

Check the total weight of steel needed for a specific volume and spacing configuration.

One connector, every AI

Concrete 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 Concrete 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.

Connect your client

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 Concrete Calculator, so you can see the experience inside your AI.

It does not authenticate your account with Concrete 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 Concrete Calculator owners hand off.

This MCP is built for professionals who need to move from dimensions to material orders without manual math errors.

  • 01

    Construction Project Managers

    They hand off dimensions to the AI to quickly generate material orders and budget estimates.

  • 02

    Structural Engineers

    They use the capability to verify reinforcement weights and volume requirements for structural designs.

  • 03

    Site Foremen

    They use it to calculate on-site mixing weights and bag counts for small pours.

FAQ

Questions Concrete Calculator owners ask.

  • 01

    How accurate are the concrete volume calculations?

    The calculations are deterministic, meaning they follow strict mathematical formulas for the dimensions you provide. You can also include a waste margin to account for real-world variables.

  • 02

    Can I use this for on-site mixing?

    Yes. The estimate_materials capability provides the specific weights of cement, sand, gravel, and water needed for mixing.

  • 03

    Does this MCP work with my existing AI capabilities?

    Yes. It works with any MCP-compatible client like Claude, Cursor, Windsurf, or VS Code.

  • 04

    Can it calculate rebar requirements?

    Yes. The calculate_rebar capability determines the total weight and length of steel reinforcement based on your spacing and bar diameter.

  • 05

    Do I need to host this myself?

    No. Vinkius hosts and manages the MCP for you. You just connect your client and start using the capabilities.

  • 06

    How does the capability handle waste?

    The calculate_volume capability includes a waste factor parameter, allowing you to add a safety margin (typically 5-10%) to the theoretical volume to account for spillage or uneven surfaces.

  • 07

    Can I calculate materials for on-site mixing?

    Yes, by using estimate_materials with the 'bagged' delivery method or by reviewing the raw material weights (cement, sand, gravel, water) provided in the output.

  • 08

    What foundation types are supported?

    The capability supports calculations for slabs, footings, piers, and walls.
