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 Development Length.
- 01
Query confinement effect
This capability evaluates how concrete cover and surrounding reinforcement impact development length. It helps you understand how confinement affects the bond strength.
- 02
Query development length
This capability calculates the fundamental development length and all individual modification factors. It's the primary way to get base embedment values.
- 03
Query rebar summary
This capability provides a complete summary of all calculated parameters for a specific bar configuration. It's useful for a quick check of all design variables.
- 04
Query splice requirement
This capability determines the necessary overlap length required when joining two reinforcing bars. Use it to calculate lap splice requirements.
Real work
What teams actually run
Rebar Splicing
Calculate the exact lap splice length needed when joining two bars of a specific diameter.
Embedment Verification
Determine the required depth for reinforcing steel in a new concrete pour.
Cover Assessment
Check if the specified concrete cover is enough to prevent splitting for a given bar size.
Design Summaries
Generate a full list of calculated parameters for a specific rebar configuration.
One connector, every AI
Concrete Development Length 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 Development Length 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 Development Length, so you can see the experience inside your AI.
It does not authenticate your account with Concrete Development Length. 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 Development Length owners hand off.
This MCP is built for professionals working in structural design and civil engineering. It allows them to offload repetitive code-based calculations to their AI agents.
- 01
Structural Engineer
Uses the MCP to verify rebar embedment and splice lengths during the design phase.
- 02
Civil Engineer
Employs the capability to check reinforcement requirements against ACI standards.
- 03
Construction Designer
Uses the calculations to ensure rebar placement meets structural integrity needs.
FAQ
Questions Concrete Development Length owners ask.
- 01
What standards does this MCP use for calculations?
This MCP uses ACI standards to determine development length and other reinforcement requirements.
- 02
Can I calculate splice lengths for rebar?
Yes, you can use the query_splice_requirement capability to find the necessary overlap length for joining bars.
- 03
Does it account for epoxy coatings on rebar?
Yes, the calculations include modification factors for epoxy coatings and other specific bar conditions.
- 04
How do I use this with Claude or Cursor?
You connect once through Vinkius, and the capabilities become available as functions your AI client can call directly.
- 05
Can it check if my concrete cover is sufficient?
Yes, the capability can evaluate how concrete cover affects development length and helps prevent splitting.
- 06
What standards does this capability follow?
The calculations are based on ACI (American Concrete Institute) standards for development length.
- 07
How do I calculate the overlap for two bars?
You can use the query_splice_requirement capability, providing the bar diameter and the previously calculated development length.
- 08
Does it account for epoxy-coated rebar?
Yes, the query_development_length capability includes a specific factor for epoxy coatings to account for reduced bond strength.
