MCP Overview - ARIS

The ARIS MCP server gives AI agents direct access to real estate tools — listing search, mortgage calculator, showing requests, and the full ARIS conversational AI — as native agent capabilities.

What is MCP?

MCP is a protocol that lets AI agents call external tools. When you add ARIS as an MCP server, your AI coding assistant can search MLS listings, calculate mortgages, and answer real estate questions directly in your conversation.

Two connection methods

Local (stdio)

npx on first use. Best for Cursor and Claude Desktop.

Hosted (HTTP)
