Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “connection_route”: Work out which ENA connection procedure a domestic installation of solar panels, batteries or both falls under: connect first and notify the.”
“Use “heat_pump_noise”: Calculate the sound pressure level an air source heat pump produces at an assessment position, and whether it meets the 37 dB(A) permitted d.”
“Use “heat_pump_running_cost”: Compare what a household spends heating on its current fuel with what the same heat would cost from a heat pump. The heat demand is worked.”
“Use “heat_pump_size”: Estimate the heat pump a UK house needs, and what it would cost to run against the fuel it burns now. IMPORTANT: MIS 3005-D requires a heat.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Ampworth calculators holds up.
Operated by Ampworth calculators (ampworth.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
This server only exposes public data — no account and no credentials are involved when you connect.
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
If Ampworth calculators adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Choose Ampworth calculators in the gate directory. No sign-in needed.
Ampworth calculators's tools are live in every AI client you've connected — with rules and logging built in.
