Frequently Asked Questions
Last updated: January 16, 2026
What does the MCP Server do?
The MCP Server exposes ATTOM property data through a set of AI-callable tools. These tools allow agents to:
Retrieve property information
Perform searches
Access metadata without writing traditional API code.
Note: The MCP Server is designed for integration with AI agents and low-code workflows.
Does the MCP Server replace the ATTOM APIs?
No. The MCP Server provides an AI-native access layer that works with tools like Claude, n8n, and Make. Traditional applications can continue using ATTOM’s standard APIs.
What counts as an MCP request?
Each tool invocation counts as one request, regardless of how much data the tool returns.
Tip: Combining multiple tools in a single workflow will consume multiple requests.
Do I need engineering resources to use MCP?
Not necessarily. The MCP Server is designed for low-code and no-code AI workflows.
Works with Copilots, workflow automation tools, and most agent frameworks
Engineering resources are only required if embedding MCP into a custom application
Can I test MCP before purchasing?
Yes. Trial access can be provided upon request, typically with:
Limited requests (e.g., 1,000) for a limited time (e.g., 30 days)
Most tools included
What tools are available?
The MCP Server includes tools for:
Property details and profiles (
get_property_report)Ownership history (
get_property_owner)Tax and assessment history (
get_property_tax_history)Sales and mortgage history (
get_property_sales_history)Automated valuation models (AVM) (
get_property_avm/get_property_avm_history)Foreclosure/distress checks (
get_property_foreclosure_status)Comparable sales (
get_property_comparables)Parcel, lot, and building information (
get_property_geocode)Rentals and home equity (
get_rental_avm,get_home_equity)Building permits (
get_permits)
See “Overview of MCP Tools” for complete examples and prompts.
Can I use MCP for internal copilots?
Yes. MCP can be integrated with most internal AI copilots and agent systems that support tool-calling workflows.
Tip: Use separate keys and environments to reduce risk when integrating with internal tools.
Is MCP secure for enterprise use?
Yes. Security and access are enforced via:
ATTOM MCP Key credentials/Oauth
Plan entitlements
TLS / HTTPS encryption
No MCP server data is stored; it acts as a real-time broker between your agent and the ATTOM API.
Does MCP enforce rate limits?
Yes. The MCP Server enforces rate limits according to your plan entitlements and will throttle requests if limits are approached.
Exceeding your quota will return a
429 Too Many Requestserror.For high-volume workflows, implement retry logic with exponential backoff to prevent failures and avoid overloading the server.
Tip: Monitor your usage regularly to stay within your monthly or daily limits.
Does MCP support batch or multi-property operations?
The MCP Server requires a property identifier to reconcile data in the ATTOM database. This can be:
An ATTOM ID
A full property address (including ZIP code for best accuracy)
Geocoordinates (latitude/longitude)
You can also query properties around a subject property (e.g., comparables) and then retrieve detailed information for those properties.
Important:
Each tool call counts as one request toward your plan limit.
Plan your workflows efficiently to avoid exceeding quotas.
Does MCP store or retain my data?
No. MCP does not persist requests or responses.
It acts as a real-time broker
Only the agent receives the retrieved data
Can I add custom tools or internal data sources?
Not currently. MCP exposes ATTOM’s standard toolset.
What happens if data is missing for a property?
The MCP tool will return the data it has.
Missing fields (e.g., no AVM, permits, or sales history) will be indicated clearly.
Agents should summarize available data and note gaps.
Which addresses work best for MCP queries?
Use full street address with ZIP code for higher accuracy
If a property cannot be found, try nearby or alternative addresses or APN (parcel number)
Can I integrate MCP with workflow automation tools?
Yes. MCP works with:
n8n
Zapier (via HTTP module)
Most AI agents that support tool-calling or API request workflows
Can MCP data be used for investment decisions?
MCP provides data analysis and valuation estimates (AVMs, comparables, tax history, equity).
It does not provide investment advice
Always recommend professional appraisal or consultation for critical decisions
