# Ratehub Mortgage — AI Connector Ratehub Mortgage publishes 4 MCP tools to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/finance/ratehub-mortgage/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Finance](https://node8.ai/ai-connectors/finance/) # Ratehub Mortgage Canadian mortgage rate comparison across banks and lenders Listed in Claude · 4 published tools · Community-listed [Claude connector docs](https://api.ratehub.ca/claude-app/mortgages/api-docs/) [ratehub.ca](https://www.ratehub.ca/) Overview ## What Ratehub Mortgage does Ratehub compares mortgage rates offered by Canadian banks and other lenders. The connector answers rate questions narrowed by home price, down payment and location, so the numbers returned reflect what an applicant with those parameters would be quoted rather than a headline figure. Fixed and variable options can be set side by side. Four tools are published and four answered. The situations the publisher names are a first purchase, a renewal at term end, and a refinance, with home equity lines of credit handled separately. ### Who it is for Canadian home buyers and owners comparing mortgage options before applying. ### Tool surface The four tools map one to one onto borrowing situations rather than onto data objects: \`get\_purchase\_rates\`, \`get\_renewal\_rates\`, \`get\_refinance\_rates\` and \`get\_heloc\_rates\`. All four read published rate tables and none of them collect an application. Availability ## Where Ratehub Mortgage is listed Ratehub Mortgage is listed in the Claude connectors directory only. Ratehub.ca has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them. The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one. Claude listing ## In the Claude connectors directory Ratehub Mortgage publishes 4 tools to Claude, a deliberately narrow surface; only 17.2% of the 1,253 Claude-listed connectors expose fewer. The median Claude-listed connector filed under Finance publishes 12, so this one sits 8 tools below its bucket's median, 140th of 159. It falls in the 4-6 tools band, which holds 16.2% of the Claude directory. ### Measured against the live endpoint A direct call to the endpoint returned 4 tools, matching the 4 the listing publishes. Probed 2026-08-07. #### Tools the server actually returns - `get_heloc_rates` - `get_purchase_rates` - `get_refinance_rates` - `get_renewal_rates` Ratehub Mortgage publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally. Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there. Publisher Ratehub.ca Verification Community-listed (61.5% of the Claude directory) Filed under Financial Services Endpoint `https://api.ratehub.ca/claude-app/mortgages/mcp` Documentation [Publisher setup docs](https://api.ratehub.ca/claude-app/mortgages/api-docs/) Published tools 4 · 4-6 tools band Depth rank in Finance 140 of 159 Snapshot August 2026 Ratehub Mortgage is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality.
