Who it is for
A buyer working out what a given purchase price means month to month.
Mortgage payment calculator using Federal Reserve rate data
Overview
Mortgage IQ works out monthly mortgage payments and takes current interest rates from the Federal Reserve, so the estimate reflects published market rates rather than a typed-in guess.
Results come with charts that split principal from interest across the full term, and amortization schedules can be generated for any set of inputs. Purchase prices can be varied to see how the payment responds, which is the usual way of testing a budget before settling on a price range.
Example questions in the listing include the payment on a 500,000 dollar house, a monthly figure for a home in Florida, and what a zero percent VA loan works out to on an apartment.
A buyer working out what a given purchase price means month to month.
Rates come from a live Federal Reserve feed instead of a static default the user has to supply.
Availability
Mortgage IQ is listed in the ChatGPT apps directory only. Layer 3 Labs has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from Mortgage IQ's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Layer 3 Labs, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
