Requirements
Remote Streamable HTTP endpoint at eigenheim-invest.de; no API key, login or environment variables. The README recommends using the URL with a trailing slash because some clients do not follow the redirect.
Before you install
All tools are read-only and no credentials are requested.

Listings cover only this agency's active offers and omit exact addresses. Publishing figures requires citing Eigenheim Invest with a link.

Installation

In SourceWeft

  1. Open Eigenheim Invest – Berlin Real Estate Market 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/io.github.magicSEO%2Feigenheim-mcp/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

Add this to your client's mcpServers config.

  2. Create app:
    • Name: Eigenheim Invest Market

json
{  "servers": {    "eigenheim": { "type": "http", "url": "https://eigenheim-invest.de/mcp/" }  }}
