Can Claude check mortgage rates today?

Yes with web search, with one caution. Rates change every week, so from memory alone Claude cannot know this week's number. With web search on, Claude can find a rate, but sites mix lender ads, daily indexes and the weekly survey, often without the date. Connect the free Mortgage Rates Today server and Claude reads the Freddie Mac Primary Mortgage Market Survey file when you ask, with the week date, the change from last week and the rate a year ago, and works out the payment on your loan amount. These are national averages, not a quote and not advice. A lender quotes your own rate from your credit, down payment and points.

A real call to the live server

We sent this to the hosted server on 2026-11-05. The answer below is the server's own text, not a mock-up. Live values will differ when you ask.

You ask

What are mortgage rates today?

Tool call

get_mortgage_rates_today {}

Server answer

The Freddie Mac average 30-year fixed mortgage rate is 7.24% for the week of 2026-10-29 (down 0.08 points from the week before, 6.17% a year ago). The 15-year fixed average is 6.60%. These are national averages for well-qualified borrowers, released on Thursdays; the next release is due 2026-11-05. Source: Freddie Mac Primary Mortgage Market Survey (PMMS), U.S. weekly averages.

Run on 2026-11-05 before that day's Thursday release, so the newest week was 2026-10-29. The server reads the newest week each time you ask.

You ask

What is the payment on a $400,000 loan at today's 30-year rate?

Tool call

calculate_mortgage_payment {"loan_amount":400000}

Server answer

A $400,000.00 30-year fixed loan at 7.24% (Freddie Mac PMMS 30-year average, week of 2026-10-29) costs $2,725.99 a month in principal and interest, $581,357.32 of interest over the full term. At 6.17% (the average a year earlier) it would be $2,442.09, a difference of $283.90 a month. Taxes, insurance and PMI are not included.

Questions

Can Claude check mortgage rates today?
Yes with web search, with one caution. Rates change every week, so from memory alone Claude cannot know this week's number. With web search on, Claude can find a rate, but sites mix lender ads, daily indexes and the weekly survey, often without the date. Connect the free Mortgage Rates Today server and Claude reads the Freddie Mac Primary Mortgage Market Survey file when you ask, with the week date, the change from last week and the rate a year ago, and works out the payment on your loan amount. These are national averages, not a quote and not advice. A lender quotes your own rate from your credit, down payment and points.
Is this the rate I will get?
No. PMMS is a national average for well-qualified borrowers with 20 percent down. Your rate depends on credit, down payment, points, loan type and lender. Ask several lenders for a Loan Estimate.
When does the number update?
Freddie Mac publishes PMMS on Thursdays, or on Wednesday when a holiday falls on Thursday. The server reads the file at call time.
Is the server free?
Yes. The Mortgage Rates Today server is free at its hosted URL with no token, key or account. The source is open on GitHub.
