Calculate Pool in ChatGPT, Claude and other AI assistants

The calculators on this site also work inside AI assistants. Ask ChatGPT or Claude how many gallons your pool holds or how much chlorine to add, and the answer is computed with the same code as the pages here, not guessed.

How to connect

ChatGPT: once the Calculate Pool app is listed in the ChatGPT app directory, add it from there and pick it in a chat. Until then, with developer mode switched on, add a custom app with the address https://calculatepool.com/mcp.

Claude: in Settings → Connectors, choose "Add custom connector" and enter https://calculatepool.com/mcp?src=claude. No sign-in is needed.

Other MCP clients: use https://calculatepool.com/mcp?src=mcp (remote MCP server, Streamable HTTP, JSON-RPC over POST, no authentication). It is listed in the MCP Registry as com.calculatepool/calculatepool.

Heater BTU per hour to raise the water a number of degrees in a set time, with a buffer for heat loss.
Standard pool sizes in gallons
pool_facts
The standard-sizes table: gallons of common inground and above-ground pools.

Every tool only reads and calculates. None of them changes anything, stores anything or needs an account.

Same numbers as the site

The server imports the same calculation modules as the calculator pages, and the automated tests check both against known answers before every release. For example:

Things to ask

Privacy and limits

The assistant sends the server only the numbers a calculation needs: dimensions, depths, gallons, chemical levels, hours and degrees. It never needs names, addresses or photos, and our code does not store or log what it receives. Your conversation itself is processed by the assistant's provider under its own privacy policy. Details: privacy policy, terms of use.

Results are estimates. Test the water before dosing, follow the product label, and add one chemical at a time. The server names no products or prices and links only to pages of this site.
