Ask the engine yourself
WattShed's pricing engine has an address anyone can use. An AI assistant asks it what a kilowatt is worth and what a fund buys in a county instead of doing the arithmetic itself, and every answer carries the engine's own notes.
The address
https://wattshed.co/mcp
The address is for an assistant, not for a browser. Opened in a browser, it brings you back to this page.
How to add it
- In an assistant
- In an AI assistant that supports custom MCP connectors, such as Claude, add a connector and paste the address. It asks for no login and no key.
- In Claude Code
- Run this one line:
claude mcp add --transport http wattshed-engine https://wattshed.co/mcp
What you can ask
Ask in plain English. The assistant picks the tool and repeats the engine's notes with the answer.
- A county
- What would a $50 million fund do in Sullivan County, Indiana?
- A price
- What is a kilowatt worth over 20 years at 6 percent?
- The case study
- What does a $10 million fund at $5,200 per kW buy in Mitchell County?
The four tools
- List counties
- Finds a county in a state and shows what the engine knows about it.
- Fund study
- What a fund buys in one county: the kilowatts and bill savings per home, the rebate, and how many homes the money reaches.
- Case study
- The Mitchell County case study, recomputed live for any fund size and price per kW.
- Price one kilowatt
- What a kilowatt is worth to a funder over a number of years at a discount rate.
What it does not do
- Read-only
- It answers questions and changes nothing. There is no login, it stores nothing, and it holds no household data.
- Price per kW
- Outside Mitchell County, the price per kW uses a state average industrial retail price, not a site's own rate, and the answer says so.
- Job cost
- No job cost is assumed unless a contractor's quote is given. The case study is the one exception: it uses the modelled cost of the job, and says so.
