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 · 4 capabilities
We ship only the actions that matter.
01-04
4 capabilities in this set.
Part of 4 available through Concrete Joint Spacing.
- 01
Analyze load transfer capacity
This capability checks if your proposed joint geometry provides enough load transfer across the joint.
- 02
Calculate optimal spacing
Use this to find the ideal horizontal distance between contraction joints to stop uncontrolled cracking.
- 03
Determine joint geometry
This capability calculates the necessary depth for a contraction cut based on slab thickness and structural needs.
- 04
Estimate sealant needs
Get an estimate of the total sealant volume required to fill joints for your specific project area.
Real work
What teams actually run
New Slab Planning
Calculate the spacing and depth for a fresh concrete pour to ensure the slab stays intact.
Material Procurement
Determine how much sealant to order before the crew arrives on site.
Structural Auditing
Check if a proposed joint design meets load transfer requirements.
Site Estimating
Get quick jointing specs for a specific slab thickness and reinforcement percentage.
One connector, every AI
Concrete Joint Spacing 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 Concrete Joint Spacing 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 Concrete Joint Spacing, so you can see the experience inside your AI.
It does not authenticate your account with Concrete Joint Spacing. 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 Joint Spacing owners hand off.
This MCP is built for professionals managing concrete pours and structural layouts.
- 01
Civil Engineers
Use it to verify structural integrity and joint spacing requirements.
- 02
Construction Managers
Use it to estimate sealant quantities and plan cutting schedules.
- 03
Concrete Contractors
Use it to determine the exact depth and spacing for on-site execution.
FAQ
Questions Concrete Joint Spacing owners ask.
- 01
How does this MCP prevent concrete cracking?
It uses the calculate_optimal_spacing capability to find the ideal horizontal distance between joints to prevent uncontrolled cracking.
- 02
Can I use this to estimate sealant costs?
The MCP provides the volume and linear meters of sealant needed via the estimate_sealant_needs capability, which you can use for your cost estimates.
- 03
Does it account for reinforcement?
Yes, you can include reinforcement percentages in your prompts to get accurate spacing and load transfer results.
- 04
What clients can I use this with?
You can use this MCP with any compatible client like Claude, Cursor, Windsurf, or VS Code.
- 05
How do I know if my joint depth is enough?
The analyze_load_transfer_capacity capability evaluates if your proposed joint geometry provides sufficient load transfer.
- 06
How do I determine the spacing between joints?
You can use the calculate_optimal_spacing capability. Provide the slab thickness, concrete type, reinforcement ratio, base friction, and the expected temperature range.
- 07
Can I estimate sealant volume?
Yes, the estimate_sealant_needs capability calculates both the total linear meters and the total volume in liters required for your specific slab area and joint dimensions.
- 08
How is load transfer capacity assessed?
The analyze_load_transfer_capacity capability evaluates the remaining un-cut thickness of the slab against the reinforcement density to ensure structural stability.
