What is the MCP MCP server?

MCP MCP server exists for a simple reason — assistants are far more useful when they can act on MCP directly instead of describing what you should do. MCP server for the ATTOM Real Estate API.

What you get

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.

  • 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

What the assistant can call

Once MCP is connected, these are the calls the assistant has available:

  • Linting — The Linting tool exposed by this server

Setting it up

Installation goes through your MCP client rather than a global install: point it at @modelcontextprotocol/inspector on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

Configuration and credentials

You will need 4 environment variables: ATTOM_API_KEY, PYPI_TOKEN, ATTOM_HOST_URL, YOUR_PYPI_TOKEN. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

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

Choosing this one

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. MCP's toolset — Linting — is a fair guide to whether it matches your workflow.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the mcp mcp server does with a few real requests.

Frequently asked questions

It connects MCP to MCP-compatible AI assistants such as Claude and Cursor, exposing 1 tool (Linting) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with MCP directly.
