Why let Claude query Ratehub's mortgage rates
Shopping for a mortgage in Canada means comparing fixed and variable offers from the big banks and other lenders, then redoing the exercise when your situation changes. With this connector, you describe your case in plain words and Claude asks Ratehub for matching rates, then lays them side by side so you can discuss the trade-offs in the same conversation.
Price a first purchase. You give the home price and the down payment: get_purchase_rates brings back matching rates, and Claude sets fixed and variable options side by side; the directory says results can be tailored by home price, down payment and location.
Prepare a renewal. To renew or extend a mortgage you already hold, get_renewal_rates fetches renewal rates to set against your lender's offer.
Weigh breaking the mortgage. Breaking and replacing an existing loan is priced with refinance rates from get_refinance_rates, while a line of credit against home equity goes through get_heloc_rates.
What it will not do: the connector looks up rates, it does not apply for a mortgage, contact a lender or lock a rate for you. It does not watch the market either; Claude only fetches rates when you ask during a conversation. We have no n8n, Make or Zapier page for Ratehub; our Integrations hub lists the platforms we cover, and the Claude connectors page gathers the others.
Five words before you connect
The Claude terms this page uses, in one minute.
- Connector
- The link you set up once between Claude and an outside service, so Claude can call on it while it answers you.
- Tool
- One named thing a connector lets Claude do. Claude chooses the tools it needs on its own, and the directory sheet lists them by name.
- Authorization
- The access you hand Claude on a service through that service's own screen. Ratehub's rates are public, so no personal login is involved here.
- Approval
- The confirmation Claude waits for before doing something that changes an account, shown in the conversation at the moment it matters.
- MCP
- The common standard behind connectors: it is what lets an assistant such as Claude talk to an outside service like Ratehub.
Add the Claude Ratehub Mortgage connector in three steps
- 01
Open the connector list
In Claude, open the settings, go to Customize then Connectors, and search for Ratehub Mortgage. On a Team or Enterprise workspace, an Owner or Primary Owner has to enable it for the organization before members can add it.
- 02
Click Connect on its row
Press Connect next to Ratehub Mortgage and follow whatever window the service opens. If the link breaks later, Disconnect then connect again: that is the documented way to repair it.
- 03
Check the permission screen
If a permission screen shows up, read it before you accept: it belongs to the service, not to Claude, and it defines the access. Here the tools return public rate data, so there is no personal account to hand over.
The 4 tools of the Ratehub Mortgage connector
Ratehub Mortgage gives Claude 4 tools: 4 that read your account, 0 that change something in it.
Four lookups, one per mortgage situation. All four only read rates; names stay as Claude displays them.
- 4 read
What Claude reads (4)
4 toolsFour rate lookups, each matching a different moment in the life of a Canadian mortgage.
get_heloc_rates
Brings back HELOC rates, for borrowing through a line of credit secured on the equity you already hold in your home, based on the details you give.
get_purchase_rates
Returns mortgage rates for buying a home. Ratehub's server also treats it as the fallback when you do not say which kind of mortgage you are after.
get_refinance_rates
Looks up rates for breaking your current mortgage and replacing it with a new one, based on the details you give.
get_renewal_rates
Fetches the rates on offer for renewing or extending a mortgage you already have, as a benchmark against your lender's proposal.
What Claude asks before it acts
By default, Claude stops and asks for your go-ahead before any action it would carry out on an account for you. The four Ratehub tools only fetch rates, and no source describes a confirmation tied to any one of them.
On Team and Enterprise workspaces, owners choose whether members may let some actions go through without being asked again. They can also restrict what a connector may do across the organization, for example allow reading and block writing, and no one overrides that from their own account. Claude works with the rights of the person who connected it and nothing beyond; with public rate data, that simply means what Ratehub shows any visitor.
Which Claude plans include it
Anthropic's general rule: remote connectors are open to all users on Claude, Cowork, Claude Desktop and mobile, and desktop extensions install in Claude Desktop.
On Team and Enterprise, an Owner or Primary Owner turns a connector on for the organization before members can connect. For Ratehub Mortgage's current status, the sheet in the official directory is the reference, linked from the button at the top of this page. No official source publishes plan availability connector by connector, so that sheet is the place to check.
What the Ratehub Mortgage connector does not do
This connector is documented by its publisher alone: neither the Claude help center nor Anthropic's developer docs have a page on it. What follows comes from the directory sheet and from Ratehub's own server.
A connector is not an automation: Claude calls its tools during a reply, and nothing fires on its own when rates move. The directory's verification badge is not a security audit, and Anthropic notes on every sheet that it does not control what a publisher's tools do, so only connect publishers you know. By default the sheet exposes only reading, which is an observed floor rather than a promise for later.
