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 · 3 capabilities
We ship only the actions that matter.
01-03
3 capabilities in this set.
Part of 3 available through Plumbing Pipe Sizing.
- 01
Calculate demand flow
This capability calculates the expected Gallons Per Minute (GPM) required for a specific total fixture load.
- 02
Get fixture unit reference
This capability retrieves the specific fixture unit value for any plumbing fixture you name.
- 03
Size pipe diameter
This capability determines the minimum pipe diameter required to meet demand while staying within your pressure limits.
Real work
What teams actually run
Residential Water Supply Design
Calculate the necessary pipe diameters for a single-family home based on the fixture count.
Commercial Plumbing Layouts
Determine GPM requirements for large buildings using fixture unit conversions.
Pressure Drop Analysis
Select pipe sizes that maintain required pressure over specific distances.

One connector, every AI
Plumbing Pipe Sizing 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 Plumbing Pipe Sizing 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.

Who it's for
Built for the work Plumbing Pipe Sizing owners hand off.
This MCP is built for professionals who need to move quickly from fixture counts to pipe specifications.
- 01
Plumbing Engineers
They hand off fixture lists to the AI to get rapid sizing results.
- 02
Construction Project Managers
They use the capability to verify pipe requirements against project specs.
- 03
Mechanical Designers
They use the calculations to inform their system layouts.
FAQ
Questions Plumbing Pipe Sizing owners ask.
- 01
What code does this MCP follow?
This MCP follows the International Plumbing Code (IPC) for all sizing calculations.
- 02
How does it handle simultaneous water use?
It uses Hunter's Curve to convert fixture units into GPM, which accounts for simultaneous demand.
- 03
Can I use this with Cursor or VS Code?
Yes, you can connect this MCP to any MCP-compatible client like Cursor, Windsurf, or VS Code.
- 04
Does it account for pipe length?
Yes, the pipe sizing capability factors in pipe length and available pressure to find the right diameter.
- 05
What information do I need for pipe sizing?
You need the required GPM, the available pressure, and the length of the pipe run.
- 06
How do I find the fixture unit value for a specific item?
You can use the get_fixture_unit_reference capability to retrieve the standard IPC unit value for any recognized plumbing fixture.
- 07
What is Hunter's Curve used for in this capability?
Hunter's Curve is used by the calculate_demand_flow capability to convert the total sum of fixture units into a realistic demand flow rate in GPM, accounting for simultaneous usage.
- 08
Can I specify a maximum pressure drop?
Yes, when using size_pipe_diameter, you can provide an optional targetPressureDropMax to ensure the selected pipe size stays within your preferred pressure limits.
