Who it is for
People running a monthly household budget who want to test purchases against it before spending.
Budget review, spend tracking, and affordability checks
Overview
Granite reports on a connected budget: what remains available, recent transactions, spend by category, and how fast money is going out compared with earlier periods. Recurring bills are projected forward, and a prospective purchase can be tested against the current month to see what it would leave behind.
Results arrive as compact widgets rather than as narrated text, so figures are laid out in structure.
Two qualifications belong in the record. Onboarding happens before any personal data is reached, and individual capabilities apply only where the connected account supports them, so not every feature is present in every setup.

Spend velocity and purchase impact scenarios push past reporting into forward projection.
Availability
Granite Finance is listed in the ChatGPT apps directory only. Granite Finance 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 Granite Finance'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 Granite Finance, 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.
