Work out car loan payments, compare loan terms and see what car price fits your monthly budget.
Connects to a US auto loan calculator. Muse can compute monthly payments, total interest and total cost for a car loan, compare two to four loan scenarios side by side, find the highest vehicle price that fits a monthly budget, and show a yearly or monthly amortization schedule.
Try asking Muse: "If I put $4,000 down on a $28,000 car at 6.5% for 60 months, what would my monthly payment be?"

CarLoanMath is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
