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 Rebar Fabrication Service.
- 01
Calculate total cut length
This capability determines the final length of the bar that needs to be cut from your raw stock.
- 02
Get bend allowance
Use this to find the centerline arc length for a specific bend.
- 03
Get hook length
This capability calculates the extra steel required to create a specific end hook.
- 04
Get bend deduction
This capability calculates the length to subtract from total segments to account for material stretch during bending.
Real work
What teams actually run
Fabrication Shop Cut Lists
Generate precise cutting instructions for complex rebar shapes including bends and hooks.
Material Ordering
Determine the total amount of raw steel stock required for a specific reinforcement project.
Quality Control
Verify that bending math used on the shop floor matches theoretical structural requirements.
Design Verification
Check that hook lengths and bend allowances meet specific engineering standards.
One connector, every AI
Rebar Fabrication Service 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 Rebar Fabrication Service 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 Rebar Fabrication Service, so you can see the experience inside your AI.
It does not authenticate your account with Rebar Fabrication Service. 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 Rebar Fabrication Service owners hand off.
This MCP is built for professionals working with reinforcement steel and structural components.
- 01
Rebar Fabricators
They hand off complex shape requirements to the AI to get precise cut lists.
- 02
Structural Engineers
They use the capability to verify that fabrication measurements align with design specifications.
- 03
Construction Estimators
They use the calculations to determine exact material quantities for steel orders.
FAQ
Questions Rebar Fabrication Service owners ask.
- 01
How does this MCP handle material stretch?
It uses the get_bend_deduction capability to calculate the exact amount of length to subtract from segments to account for stretch during bending.
- 02
Which AI clients can I use with this MCP?
You can use any MCP-compatible client, including Claude, Cursor, Windsurf, and VS Code.
- 03
Can I calculate total steel needed for a single piece?
Yes, the calculate_total_cut_length capability determines the exact raw stock length required for a finished bar.
- 04
Does this capability work for different rebar sizes?
Yes, the calculations are based on the specific diameter and geometry you provide to your agent.
- 05
Do I need to host the MCP myself?
No, Vinkius hosts and manages the MCP for you, so it is ready to use as soon as you connect your client.
- 06
How does this capability account for steel stretching?
The capability uses get_bend_deduction to calculate the length lost due to material stretch during the bending process, ensuring the final dimensions are correct.
- 07
What hook types are supported?
It supports standard and seismic hooks, such as 90_DEGREE and 135_DEGREE, via the get_hook_length capability.
- 08
Can I calculate the total length in one step?
Yes, use the calculate_total_cut_length capability to get the total cut length, bend deduction, hook length, and allowance in a single response.
