Redfin MCP Server

A hosted Model Context Protocol (MCP) server that gives Claude, Cursor, Windsurf and any other MCP client two read-only Redfin tools. Search for-sale, for-rent and sold listings with the filter set Redfin shows a visitor, and read one property page in full, both as structured JSON, with no MLS licence and nothing to host.

It reads public Redfin pages that a signed-out visitor can see.

1,000 free credits every month, no card required, which is 200 Redfin calls at the 5-credit rate.

What you need

An MCP client and a HasData API key from the dashboard, free to create with no card, and the free tier covers about 200 calls a month at the 5-credit rate. This is a remote server, so the simplest path is a URL and an x-api-key header, with no container to run. A client that only speaks stdio reaches it through a thin launcher, published as @hasdata/redfin-mcp on npm and hasdata-redfin-mcp on PyPI, shown below.

Quick start

The server URL is the same for every client. We run it hands-on in Claude Code and Claude Desktop. The other blocks follow each client's own documented format for a remote server.

Clients with OAuth support can add the same URL as a connector and sign in without putting a key in a config file.

claude mcp add --transport http redfin "https://mcp.hasdata.com/api/mcp?apis=redfin" \
  --header "x-api-key: HASDATA_API_KEY"

Settings, then Connectors, then Add custom connector, then paste https://mcp.hasdata.com/api/mcp?apis=redfin and sign in.

For the config-file route, Claude Desktop loads only local (stdio) servers, so it reaches a remote server through a stdio launcher. The @hasdata/redfin-mcp package is that launcher, and it reads the key from the environment. Add this to claude_desktop_config.json:

{
  "mcpServers": {
    "redfin": {
      "command": "npx",
      "args": ["-y", "@hasdata/redfin-mcp"],
      "env": { "HASDATA_API_KEY": "YOUR_KEY" }
    }
  }
}

For Python instead of Node, swap the launcher for the PyPI package, which uvx runs without a manual install:

{
  "mcpServers": {
    "redfin": {
      "command": "uvx",
      "args": ["hasdata-redfin-mcp"],
      "env": { "HASDATA_API_KEY": "YOUR_KEY" }
    }
  }
}

~/.cursor/mcp.json for every project, or .cursor/mcp.json for one:

{
  "mcpServers": {
    "redfin": {
      "url": "https://mcp.hasdata.com/api/mcp?apis=redfin",
      "headers": { "x-api-key": "HASDATA_API_KEY" }
    }
  }
}

~/.codeium/windsurf/mcp_config.json. Windsurf calls the field serverUrl, not url:

{
  "mcpServers": {
    "redfin": {
      "serverUrl": "https://mcp.hasdata.com/api/mcp?apis=redfin",
      "headers": { "x-api-key": "HASDATA_API_KEY" }
    }
  }
}

.vscode/mcp.json in the workspace:

{
  "servers": {
    "redfin": {
      "type": "http",
      "url": "https://mcp.hasdata.com/api/mcp?apis=redfin",
      "headers": { "x-api-key": "HASDATA_API_KEY" }
    }
  }
}

Example prompts

Each of these lands on one tool, or on two in sequence when the second needs the URL the first returns.

• Find three-bedroom houses for sale in 78741 under $500,000 and sort them by price per square foot.

• What sold in Austin in the last three months, and how does that compare with what is listed now?

• Pull the full property page for this Redfin URL and summarise the condition from the description.

• Which rentals in Austin allow dogs and include in-unit laundry?

• Show me for-sale homes in the Austin Independent School District where the assigned elementary school rates 8 or better.

• Find fixer-uppers built before 1970 in this zipcode that have been on Redfin more than 30 days.

A prompt that names a market goes to the search tool. A prompt that hands you a Redfin URL goes straight to the property tool. Searching for a full street address is a third case, covered below, because it answers with one property rather than a list.

Tools

Two tools, 5 credits per successful call.

Get Redfin real estate listings

hasdata_redfin_listing_getRealEstateListings

A page of listings for a location, or one property when the location is a single address.

Two parameters are required, and the rest of the schema mirrors Redfin's own filter panel.

The filters are named after the nested structure Redfin uses internally, flattened with underscores, so they have to be passed exactly as the schema spells them. price_min_ and price_max_ are the price band, beds_min_ and beds_max_ the bedroom count, monthlyPayment_interestRate_ a mortgage assumption. A doubled underscore marks an array.

The ones worth knowing:

A market search returns searchInformation with totalResults, a properties array of 40, and pagination with currentPage, nextPage and an otherPages map. A for-sale or sold property carries id, mlsId, url, homeType, status, price, beds, baths, area, yearBuilt, daysOnSite, addressRaw, a parsed address, latitude, longitude, description, atAGlanceFacts and photos.

{
  "id": 31625298,
  "mlsId": "2190201772333567097",
  "url": "https://www.redfin.com/TX/Austin/1721-Deerfield-Dr-78741/home/31625298",
  "homeType": "House",
  "status": "FOR_SALE",
  "price": 675000,
  "beds": 3,
  "baths": 2,
  "area": 1667,
  "yearBuilt": 1963,
  "daysOnSite": 0,
  "addressRaw": "1721 Deerfield Dr, Austin, TX 78741",
  "address": { "street": "1721 Deerfield Dr", "city": "Austin", "state": "TX", "zipcode": "78741" },
  "latitude": 30.231372,
  "longitude": -97.734893,
  "atAGlanceFacts": [
    { "factLabel": "Property Type", "factValue": "Single-family" },
    { "factLabel": "Year Built", "factValue": "1963" },
    { "factLabel": "Price/Sq.Ft.", "factValue": "$405" }
  ]
}

A rental is a building rather than a home, so type: forRent returns a different shape. price, beds, baths and area each become a { min, max } object across the available units, and the entry adds propertyName, availableUnits, agentEmail and agentPhone while dropping mlsId, homeType, yearBuilt and daysOnSite.

{
  "id": "31510362",
  "propertyName": "The Sonata",
  "status": "FOR_RENT",
  "availableUnits": 12,
  "price": { "min": 745, "max": 1300 },
  "beds": { "min": 1, "max": 2 },
  "baths": { "min": 1, "max": 2 },
  "area": { "min": 474, "max": 976 },
  "addressRaw": "1070 Mearns Meadow Blvd, Austin, TX 78758"
}

Get Redfin property details

hasdata_redfin_property_getPropertyDetails

One property page in full, by its Redfin URL.

Returns a property object. On top of everything the search result carries, it adds propertyDetails, schools, nearby, agentInfo, viewsActivity, openHouseSchedule, updatedAt, a geo object and the full photos collection, which ran to 61 images on the property below.

propertyDetails is the specification block, grouped into parking, interior, exterior, utilities and publicFacts. Each group is an array of labelled sections, and each section is an array of label and value pairs, so it reads as the page presents it rather than as a typed object. Look up a fact by its label instead of by position.

schools.assignedSchools carries the catchment schools with greatSchoolsRating, parentRating, distanceInMiles and a servesHome flag, which is the field that says whether the school actually serves this address.

{
  "id": 31625298,
  "homeType": "Single Family Residential",
  "status": "COMING SOON",
  "price": 675000,
  "beds": 3,
  "baths": 2,
  "area": 1667,
  "yearBuilt": 1963,
  "geo": { "latitude": 30.231372, "longitude": -97.734893 },
  "updatedAt": "Sep 9, 2026 4:04 AM",
  "viewsActivity": { "views": 98, "favorites": 5 },
  "agentInfo": {
    "agentName": "Lilly Rockwell",
    "agentPhoneNumber": "512-413-1975",
    "brokerName": "Compass",
    "brokerPhoneNumber": ""
  },
  "propertyDetails": {
    "parking": [{ "parkingInformation": [{ "label": "Has Garage", "value": "yes" }] }],
    "utilities": [{ "utilitiesInformation": [{ "label": "Has Air Conditioning", "value": "yes" }] }]
  },
  "schools": { "assignedSchools": [{ "greatSchoolsRating": 6, "parentRating": 5, "servesHome": true }] }
}

Errors and failure paths

Plan for these rather than assuming a happy path.

soldWithinOption is currently broken and silently returns for-sale homes labelled SOLD. Passing any of its values puts the value straight into the Redfin filter, Redfin does not recognise it, and the response is the active for-sale list with status stamped as SOLD. Every listing came back identical to the plain for-sale search in our checks. Leave the parameter off. type: sold on its own works correctly and covers the last three months, which is Redfin's own default window.

The search tool returns three different shapes, and which one you get depends on the keyword. A market keyword answers with searchInformation, properties and pagination. A full street address or a named building answers with a single property object and no properties array, no searchInformation and no pagination. A rental search answers with the range-shaped entries shown above. Branch on the presence of properties before you iterate it.

totalResults tops out at 350, and that is a ceiling rather than a count. Austin and New York both report 350 while a single zipcode reports 168 and a small town 57. Pagination stops at nine pages of 40. To enumerate a large market, slice it by zipcode, price band or home type instead of paging, because there is no page ten.

Sold search does not give you sold prices as a separate field. price holds whatever the page shows for that status, so a for-sale price and a sold price arrive in the same field. Read status alongside it every time.

There is no price history, tax history or Redfin Estimate in the property response. Those sit on the page but are not in what the tool returns today. What you get instead is propertyDetails.publicFacts, which carries the assessor-style facts as label and value pairs.

nearby.pointsOfInterest is nearby places, not comparable sales. Its categories come from a third-party places dataset and are frequently wrong, so a title loan office can arrive tagged as a bar. Use the names and coordinates, and do not trust the category.

openHouseSchedule can be an array holding an empty object when the page has the section but no dates in it. Test the contents, not the length.

brokerPhoneNumber and other agent fields come back as empty strings rather than null. Treat empty string as absent.

Results that carry data also carry a requestMetadata.id worth quoting in support.

Pricing, free tier and limits

Each Redfin tool costs 5 credits per successful call. Response size does not change the price, so a 40-listing page and a single property cost the same.

The free tier is 1,000 credits every month with no card, which is 200 Redfin calls at the base rate. It renews with the billing cycle, so a low-volume agent runs on the free tier indefinitely.

Paid plans start at $49 a month for 200,000 credits, which is 40,000 calls. The unit price falls with volume, from $1.23 per 1,000 calls on the entry plan to $0.50 on Business, $0.42 on Growth and $0.37 on the largest high-volume plans.

Your plan also sets concurrency. The free tier allows 1 request at a time, Startup 15, Business 30, Growth 50, and the high-volume plans run from 200 to 1,500. Handle the overflow case defensively in anything unattended, because an agent that walks a list of properties will reach the ceiling before you do.

A request that comes back non-200 is not billed. A successful call that finds nothing is still a call.

Tool selection

Start from what the prompt gives you. A market, a zipcode or a school district goes to the search tool. A Redfin URL goes straight to the property tool. Spending a search call to reach a URL you already have is the most common waste.

Then pick by depth. The search result is enough for ranking, price sweeps and market summaries, and it already carries price, beds, baths, area, year built and days on site. The property tool is the only one that returns the specification block, the assigned schools and the listing agent, and it is worth one call per property you actually care about rather than one per row.

Filter server-side. The schema mirrors Redfin's filter panel precisely, so a query like "three beds, under $500k, built before 1970, in this zipcode" is one call with four parameters, not a page sweep followed by local filtering.

How it compares

There is no public Redfin API, so the real alternative is an MLS or IDX feed.

The row that decides it is eligibility. An MLS feed is the authoritative source and it needs a licence you cannot buy as a developer, which rules it out for research, prototypes and anything an agent does on your behalf. When you are a brokerage with a feed already, the feed is more complete and more current, and you should use it.

FAQ

Is there an official Redfin MCP server?

Redfin does not publish one, and it does not publish a public API either. This one is maintained by HasData and reads public Redfin pages.

What is a Redfin MCP server?

An MCP server exposes tools an AI client can call. This one turns Redfin search results and property pages into JSON an agent can reason over, without a browser or a scraping library in your stack.

Do I need an MLS licence or a Redfin account?

No. The only credential is your HasData key.

Why does searching an address return one property instead of a list?

Because Redfin resolves a full street address to that property's page rather than to a result set. The tool passes that through, so the response holds a single property object in the same shape the property tool returns. It is a useful shortcut when you have an address but not a URL.

How do I pull every listing in a city?

You cannot, in one sweep. Redfin caps a result set at 350 across nine pages, so a large market has to be cut into smaller queries by zipcode, price band or home type, and the slices stitched together.

Can I filter sold listings by date?

Not reliably right now. type: sold works and returns Redfin's default three-month window, but soldWithinOption is not being translated into a filter Redfin accepts, and passing it returns active listings labelled SOLD. Leave it off until that is fixed.

Does it cover rentals?

Yes, through type: forRent. Expect the range shape rather than the single-home shape, because a rental result is a building with several available units.

Can I use this together with other HasData APIs?

Yes. One key covers everything, and one endpoint serves them all through the apis parameter. Point a client at ?apis=redfin,zillow to get both tool sets in one connection, or at mcp.hasdata.com/api/mcp for the full catalogue.

Is HasData affiliated with Redfin?

No. HasData is an independent service and is not affiliated with, endorsed by, or sponsored by Redfin. Redfin is a trademark of its respective owner. The tools work with publicly available data only, and you are responsible for using the results in line with Redfin's terms and the law that applies to you.

Compliance and personal data

Listings carry agent contact details. A for-sale property returns agentInfo with a name and a direct phone number, and a rental returns agentEmail and agentPhone. Those belong to identifiable people, published in a professional capacity, which does not take them out of scope of the GDPR or the CCPA. Marketing to them is regulated separately again, and real estate agents are a common target of exactly that, so check your obligations before you build a contact list. Market analysis does not need those fields at all.

Development

The launcher is a thin stdio bridge to the remote server, so there is nothing to build.

npm install
HASDATA_API_KEY=your_key_here npm test

The tests in test/ assert the tool contract, the part that can break without a commit here. They check that ?apis=redfin returns the expected tool count, that no name changed, that every tool still declares its required parameters and carries a description, that the filter enums this README documents are still the ones the schema offers, and that the key in use is actually accepted. That last check calls a tool for real and costs 5 credits, which is the price of a canary that can fail for the right reason.

The contract suite also runs weekly on a schedule, because the upstream tool list can change without anyone touching this repository.

Contributing

A tool table, a response sample or a documented behaviour that does not match reality is worth an issue. There is a template for exactly that. Pull requests are welcome for the same, and for anything in the launcher.
