## Description
ATTOM MCP — Premium real estate data from ATTOM Data Solutions

## Tools
Capabilities this server exposes over MCP:

- **attom_property_detail** — "Property details for [address]" / "specs of [house]" / "how many bedrooms / bathrooms" / "year built" / "square footage" / "lot size" — full property characteristics for a US residential or commercial address. Returns lot size, square footage, bedrooms, bathrooms, year built, construction type, and heating/cooling systems from ATTOM Data Solutions (the premium US real estate dataset). Use whenever an agent needs structured property attributes by address.
- **attom_property_search** — "Find houses / homes / properties / real estate for sale or owned in [ZIP]" / "search properties near [coords]" / "homes in [neighborhood]" — search US residential and commercial properties by ZIP or lat/lng radius with filters (beds, baths, year built, property type). Returns matching addresses and ATTOM property IDs. Use first when you need to find candidate addresses, then call attom_property_detail / attom_avm / attom_sales_history on the picks.
- **attom_sales_history** — "When was [house] last sold" / "sale history of [property]" / "previous owners of [address]" / "what did [house] sell for last time" — complete sales/transaction history for a US property by address. Returns sale dates, prices, deed types, and buyer/seller details from public deed records via ATTOM.
- **attom_avm** — "What's [house] worth" / "home value of [address]" / "Zestimate alternative" / "estimated value of [property]" / "how much is [home] valued at" — automated valuation model (AVM) for any US residential property. Returns ATTOM's estimated market value, confidence score, and low/high range. Use for instant home-price questions; pair with attom_sales_history for recent comparable sales.
- **attom_assessment** — "Property tax / taxes on [address]" / "assessed value of [house]" / "tax bill for [property]" / "what does the county say [home] is worth" — county tax-assessor record for a US property. Returns assessed value, market value, tax amount, tax year, and historical trends from public assessor data via ATTOM.
- **attom_sales_trend** — "Housing market trends in [ZIP]" / "median home price in [area]" / "is [ZIP] heating up or cooling" / "sales volume in [neighborhood]" — aggregated real estate market trends by ZIP. Returns average/median sale price, sales volume, and price changes monthly / quarterly / yearly across a date range. Use for market-direction questions before pulling individual addresses.
- **attom_rental_avm** — "How much can I rent [house] for" / "estimated rent for [address]" / "rental income on [property]" / "rental yield of [home]" — rental AVM for a US residential property. Returns estimated monthly rent, rental yield percentage, and rental value range. Use for landlord / investor / cash-flow analysis questions.
- **attom_school_search** — "Schools near [address]" / "what school district is [house] in" / "best schools in [area]" / "public schools around [coords]" — find K-12 schools near a US location by lat/lng radius. Returns school name, type (public/private), grade levels, distance, and performance rankings. Use for relocation / family-housing questions paired with property search.

## Documentation

## What Attom MCP server does

The Attom MCP server gives MCP-compatible AI agents access to ATTOM Data Solutions property records. ATTOM covers approximately 155 million residential parcels nationally, along with commercial records in major metropolitan areas. Available data includes property details, tax records, automated valuations, comparable sales, ownership history, neighborhood demographics, and risk overlays such as flood and wildfire information.

Core property questions map to dedicated tools. `attom_avm` returns an automated valuation with a low and high range. `attom_tax_history` provides reported annual tax assessments. `attom_comps` finds recent nearby sales, while `attom_market_stats` provides broader market context. The README also references property-detail and commercial endpoints, although their complete schemas are not listed here.

This package belongs in the 🏠 Real Estate category when an agent needs structured US property data rather than general web search. It can support valuation lookups, tax research, comparable-sale analysis, and market comparisons.

## How it works

The Attom MCP server is available in two forms. The hosted option uses the Pipeworx gateway at `https://gateway.pipeworx.io/attom/mcp`. A connection to this endpoint lists the ATTOM pack tools alongside shared Pipeworx tools, including `ask_pipeworx`, `discover_tools`, `search_within`, and `remember`/`recall`. The full gateway endpoint is also available when an agent needs direct access to all packs.

A local package is available through `npx -y @pipeworx/mcp-attom`. It communicates over stdin and stdout using MCP and exposes only the ATTOM pack tools, without the gateway's shared meta-tools. The gateway's `ask_pipeworx` tool can also accept a plain-English question and route it to a suitable tool.

Address formatting affects results. Put the street portion in `address1` and the city, state, and ZIP in `address2`. For useful comparables, apply client-side filters for square footage, bedrooms, bathrooms, and sale date because the default nearby sales are not necessarily similar properties.

## Setup and configuration

The hosted connection can be added to an MCP client with the gateway URL. For local use, configure the client to run `npx` with the `@pipeworx/mcp-attom` package, or run that command directly to verify startup.

ATTOM requires a paid API key. With the bring-your-own-key option, obtain a key from ATTOM's developer portal and pass it to a tool as `_apiKey`. Alternatively, a Pipeworx Housing Vertical subscription can front the ATTOM relationship, in which case `_apiKey` is not required and usage is billed to the Pipeworx account.

## Tools and capabilities

- Look up automated property valuations with `attom_avm`.
- Retrieve annual property tax records with `attom_tax_history`.
- Find nearby recent sales with `attom_comps`.
- Compare broader market conditions with `attom_market_stats`.
- Access property, ownership, demographic, and risk data exposed by the ATTOM pack.
- Query the pack through the Pipeworx gateway or use its local stdio implementation.

## Limitations and notes

ATTOM records are commercial data and are not uniformly real-time. County assessor updates vary, with many counties reporting annually; AVMs recalibrate monthly. Recent tax records may therefore lag the current year by six to eighteen months.

The Attom MCP server may not return a match for some rural counties or tribal lands. Commercial properties can use different schemas from residential properties, and most tools default to residential data. Report both `valueLow` and `valueHigh` with an AVM result instead of presenting only its point estimate.
