MCP server for the ATTOM Real Estate API

ATTOM API MCP Server

An MCP server for the ATTOM API, providing real estate data via the MCP protocol. This server acts as middleware, exposing the ATTOM API endpoints as MCP tools that can be used by AI agents.

Features

• MCP interface for ATTOM API endpoints
• Comprehensive API coverage for property data, valuations, assessments, and sales
• Structured error handling and logging
• Configurable via environment variables
• Packaged as a Python CLI tool for easy deployment

Prerequisites

• Python 3.11 or higher
• uv for dependency management
• An ATTOM API key

Installation

Using UVX (Recommended)

The easiest way to install and run the ATTOM API MCP Server is via uvx:

uvx mcp-server-attom --help

This will download and run the tool directly without requiring a permanent installation.

To install it permanently:

uv tool install mcp-server-attom

Local Development

1. Clone this repository:

git clone https://github.com/nkbud/mcp-server-attom.git
cd mcp-server-attom

2. Install dependencies:

uv sync --locked --all-extras --dev

3. Create a .env file with your ATTOM API key:

cp .env.example .env
# Edit .env and add your ATTOM API key

Usage

Running as a CLI Tool

Start the server using the mcp-server-attom command:

# If installed via uv tool install
mcp-server-attom --port 8000 --host 0.0.0.0

# Or run directly via uvx
uvx mcp-server-attom --port 8000 --host 0.0.0.0

Available command-line options:

• --host: Host to bind the server to (default: 0.0.0.0)
• --port: Port to bind the server to (default: 8000)
• --log-level: Logging level (debug, info, warning, error)
• --reload: Enable auto-reload on code changes

Running Locally During Development

Start the server during development:

python -m src.server

This will start the server on http://localhost:8000.

Making Requests

The server exposes MCP tools for various ATTOM API endpoints. Here's an example of using the property_detail tool:

await mcp.tools.property_detail(
    attom_id="145423726"  # OR
    # address="123 Main St, New York, NY 10001"  # OR
    # address1="123 Main St", address2="New York, NY 10001"  # OR
