Cloud cost data for your AI assistant
An MCP server that gives Claude, Cursor or any MCP client verified cloud rates and the same cost models behind the calculators on this site — with the vendor source and verification date attached to every answer.
No account. No API key. No email.

}It reaches nothing
No network calls at all — every rate and model is compiled into the bundle, so it works offline. It holds no customer data and cannot reach an account. Finitizer’s authenticated MCP server is a separate product that shares no code with this one.
Every answer is attributable
Each response carries the vendor URL the rate came from, the date a human last read it, and a link to the page showing the working. An assistant can tell you how current a figure is instead of guessing.
Same models as the site
These are the engines behind the calculators here, not a simplified copy — including the parts that make the numbers come in lower than a vendor calculator’s, and honest.

Rates are compiled in at publish time and each carries a verification date. The oldest AWS rate in the current build was read on 4 Aug 2026, across 11 rate groups. The publishing repo runs a build gate that fails on anything past its limit, so a stale package is one that has not been republished rather than one with quietly wrong numbers — and list_rate_freshness lets an assistant check before it answers.
This one answers from a rate card. The product answers from your bill.
Everything here is list prices and models. Finitizer connects read-only and keyless to your actual accounts, applies your negotiated rates, and finds the specific resources costing money — then ships the fix as a Terraform PR or a Jira ticket. There is an authenticated MCP server for that too.
