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 · 4 capabilities

Capability set01 / 01

01-04

4 capabilities in this set.

Part of 4 available through Rebar Estimator.

  1. 01

    Calculate longitudinal reinforcement

    This capability calculates the quantity of primary bars running the length of a structural element.

  2. 02

    Calculate transverse reinforcement

    Use this to find the total amount of stirrups or ties needed for an element.

  3. 03

    Estimate total project rebar

    This capability provides a high-level summary of all reinforcement for a single structural element.

  4. 04

    Get element type details

    This capability retrieves standard reinforcement characteristics for specific element types like slabs or beams.

Real work

What teams actually run

01

Beam Reinforcement

Input beam dimensions and bar spacing to get the exact weight of steel required.

02

Column Steel Estimation

Calculate the number of longitudinal bars needed based on column width, depth, and cover.

03

Slab Material Planning

Use standard slab characteristics to estimate reinforcement needs for floor systems.

04

Project Bidding

Generate quick material summaries to build up cost estimates for structural steel.

One connector, every AI

Rebar 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.

Building your own app? The connector is yours to use.

You don't need a client to put Rebar 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.

Connect your client

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 4 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 Rebar Estimator, so you can see the experience inside your AI.

It does not authenticate your account with Rebar 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 Rebar Estimator owners hand off.

This MCP is built for professionals in the construction and structural engineering space who need to move from design dimensions to material quantities quickly.

  • 01

    Structural Engineers

    Hand off design dimensions to the agent to get rapid reinforcement counts.

  • 02

    Quantity Surveyors

    Use the agent to generate material estimates for project bidding and procurement.

  • 03

    Construction Managers

    Verify steel requirements against site plans using the agent's calculations.

FAQ

Questions Rebar Estimator owners ask.

  • 01

    What structural elements can this MCP calculate?

    The MCP is designed for elements like beams, columns, and slabs.

  • 02

    Does the rebar estimate include waste and lap lengths?

    Yes, the estimate accounts for concrete cover, lap lengths, and waste factors.

  • 03

    Can I use this with Claude or Cursor?

    Yes, you can connect this MCP to any compatible client like Claude, Cursor, or Windsurf.

  • 04

    How does it handle standard reinforcement factors?

    The agent can use the get_element_type_details capability to pull standard characteristics for specific elements.

  • 05

    Does this provide the total weight of the steel?

    Yes, the estimate_total_project_rebar capability provides a summary of both total weight and total length.

  • 06

    What structural elements are supported?

    The server supports standard elements including beams, columns, slabs, and footings via the get_element_type_details capability.

  • 07

    How is the total weight calculated?

    Total weight is calculated by determining the effective length of bars (subtracting concrete cover), adding required lap lengths, and applying the steel density constant.

  • 08

    Can I include a waste factor in my estimate?

    Yes, all calculation capabilities allow for an optional wasteFactor to account for cutting losses and site handling.
