Search SimplyRETS MLS listings and open houses; read listing and market analytics.
The publisher's own server: Ably MCP by usefulapi
Hosted MCP server that lets an assistant search SimplyRETS MLS listings and open houses and read listing and market analytics.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.usefulapi%2Fsimplyrets/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Use SimplyRETS from Claude, Cursor, or any MCP client — search MLS listings and open houses from your SimplyRETS feed, read single listings, agents and offices (agents and offices need the respective SimplyRETS API add-ons), plus listing and market analytics (all read-only). Hosted, no local install: connect with your SimplyRETS API key and secret.
