Read IDX Broker leads, agents, listings and MLS data; create and update leads and notes.
The publisher's own server: Ably MCP by usefulapi
Hosted MCP server for IDX Broker accounts: read leads, agents, listings and MLS data, and create or update leads and notes.
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%2Fidx-broker/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 IDX Broker from Claude, Cursor, or any MCP client — look up leads and what they viewed, searched and saved, agents and offices, your account's own featured, sold, off-market and supplemental listings, saved links, widgets and MLS metadata, and create or update leads and add lead notes (each write needs an explicit confirmation). Hosted, no local install: connect with an IDX Broker access key.

Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your IDX Broker credentials.
