When to use it

Requirements
Remote streamable HTTP endpoint at 4ai.ai; no authentication, environment variables or headers declared. Network access is needed.
Before you install
It is a sales channel for one owner's portfolio: results and offer links lead to 4ai listings, and the server asks assistants to always surface the offer link. Value estimates are free, automated figures, not appraisals. Buying happens on the external site, outside the assistant.

Installation

In SourceWeft

  1. Open 4ai – premium .ai domains for sale in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

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/ai.4ai%2Fdomains/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.

Read the install guide the agent follows
