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 Plumbing Fixture Units.

  1. 01

    Estimate minimum pipe diameter

    This capability finds the smallest pipe diameter that safely handles a specific drainage or water supply load. It checks the load against allowed thresholds for different pipe types.

  2. 02

    Aggregate building implements

    This capability sums up fixture loads from multiple rooms. It calculates the total cumulative load for an entire building.

  3. 03

    Calculate room fixture load

    This capability calculates the combined DFU and WSFU for a single room. It multiplies fixture values by their quantities and sums them for a final total.

Real work

What teams actually run

01

Residential Bathroom Design

Calculate the exact fixture load for a single bathroom to ensure proper sizing.

02

Multi-Unit Building Planning

Sum the loads from every apartment to find the total building demand.

03

Pipe Sizing Verification

Check if a specific pipe diameter is large enough for a calculated load.

04

Code Compliance Audits

Verify that your calculated pipe diameters meet IPC or UPC standards.

Automate a task

Put Plumbing Fixture Units to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

Plumbing Fixture Units 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 Plumbing Fixture Units 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.

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 Plumbing Fixture Units, so you can see the experience inside your AI.

It does not authenticate your account with Plumbing Fixture Units. 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 Plumbing Fixture Units owners hand off.

Plumbing engineers and designers use this to automate repetitive load calculations.

  • 01

    Plumbing Engineer

    Hands off fixture lists to the AI to get rapid DFU and WSFU totals.

  • 02

    MEP Designer

    Uses the capability to quickly size branches and stacks during the design phase.

  • 03

    Construction Estimator

    Provides load data to verify material requirements for plumbing systems.

FAQ

Questions Plumbing Fixture Units owners ask.

  • 01

    What plumbing standards does this MCP follow?

    The calculations are based on IPC and UPC standards.

  • 02

    Can I use this to size vertical stacks?

    Yes, you can use the pipe diameter capability to find the minimum size for vertical stacks based on the load.

  • 03

    How do I calculate the total load for a whole building?

    You use the aggregate capability to sum the loads from all individual rooms.

  • 04

    Does this work with Cursor or VS Code?

    Yes, it works with any MCP-compatible client including Cursor, Windsurf, and VS Code.

  • 05

    What is the difference between DFU and WSFU?

    DFU refers to Drainage Fixture Units and WSFU refers to Water Supply Fixture Units, both of which this MCP calculates.

  • 06

    How do I calculate the load for a single room?

    Use the calculate_room_fixture_load capability by providing a JSON array of fixtures, where each object includes the fixture type and its quantity.

  • 07

    Can I calculate the total load for an entire building?

    Yes, use the aggregate_building_load capability by passing in the results from your individual room calculations.

  • 08

    How does the pipe diameter estimation work?

    The estimate_minimum_pipe_diameter capability compares your current DFU or WSFU load against standard capacity limits for both horizontal branches and vertical stacks to find the smallest required diameter.
