LABSCO SUMMARY

Rate queries end in a file, not a wall of text.

A rate comparison is a table, and the useful version of it is one you can open in a spreadsheet — asking for CSV saves the file locally and returns a working download link, which is why the file-management tools exist alongside the rate ones. Streaming mode exists because a full rate sweep can outlast a normal tool call, and it hands back a handle instead of failing.

What it is

A server on the RateSpot API that brings real-time mortgage rates into a conversation. Beyond rates it compares loan products, calculates monthly payments, searches foreclosure listings, and writes any result to a CSV file with a download link rather than leaving it as text in the reply.

What you get

  • get-mortgage-rates returns current rates for a scenario — ZIP code, credit score, property value, down payment
  • compare-loan-products puts loan products side by side; calculate-monthly-payment breaks down the payment
  • get-streaming-results retrieves a long-running request's results, so a slow query returns a handle instead of timing out
  • Any tool asked for format="csv" saves a timestamped file and hands back a link; list-saved-files, get-download-link and delete-csv-file manage them
  • analyze-csv-file, get-file-summary and compare-csv-files read the saved output back
  • Foreclosure listings search with interactive map display

Requirements

A RateSpot API key — sign up free at app.ratespot.io and copy the key from Account Settings. The simplest install is the Desktop Extension: download the .dxt file from the repository's releases, double-click it into Claude Desktop, and paste the key when prompted; no Node.js, terminal or config file involved. Alternatively, clone the repository and run npm install then npm run build. The local file server for CSV downloads listens on port 3001.
