Propstack MCP Server

Connect AI assistants (Claude, ChatGPT) to your Propstack real estate CRM.

Verbinden Sie KI-Assistenten mit Ihrem Propstack-CRM — Kontakte verwalten, Objekte durchsuchen, Deals pflegen, Besichtigungen planen und Suchprofile erstellen, alles per Sprache oder Chat.

What you can do / Was Sie damit machen koennen

• Contact management — search, create, update, and tag contacts with GDPR tracking
• Property search & management — filter by price, rooms, area, status; create and update listings
• Deal pipeline — create deals, move through stages, track win/loss rates
• Buyer matching — create search profiles from natural language ("3-Zimmer in Berlin, bis 400k, mit Balkon") and auto-match to new listings
• Task & calendar — log call notes, set follow-up reminders, schedule viewings
• Email — send templated emails linked to contacts and properties
• 360-degree contact view — get a complete briefing before every call
• Pipeline dashboards — deal counts and values per stage, stale deal alerts
• Lead intake — one-call workflow: dedup, create contact, log notes, create deal, set reminder

Data protection (DSGVO): Using this server sends personal data from your Propstack CRM into the LLM you connect (Claude, ChatGPT, …). You — the Propstack customer — remain the data controller. See Datenschutz (DSGVO) for responsibility, legal basis, the fields data-minimization parameter, and notes on automated decisions.

Quick Start

1. Set your API key

export PROPSTACK_API_KEY=your_api_key_here

2a. Claude Desktop

Add to your Claude Desktop config (claude_desktop_config.json):

{
  "mcpServers": {
    "propstack": {
      "command": "npx",
      "args": ["-y", "propstack-mcp-server"],
      "env": {
        "PROPSTACK_API_KEY": "your_api_key_here"
      }
    }
  }
}

2b. Claude Code (CLI)

Add to your project's .mcp.json:

{
  "mcpServers": {
    "propstack": {
      "command": "npx",
      "args": ["-y", "propstack-mcp-server"],
      "env": {
        "PROPSTACK_API_KEY": "your_api_key_here"
      }
    }
  }
}

2c. ChatGPT and claude.ai (web / mobile)

These clients only connect to remote MCP servers over an HTTPS URL. They cannot start a local npx command, so this server can't be added to them directly — use Claude Desktop, Claude Code, Cursor or another local client instead.

If you need ChatGPT or the claude.ai apps, the server has to run behind an authenticated HTTPS endpoint. Do not expose it through an open tunnel or an unauthenticated stdio-to-HTTP bridge: anyone with the URL would get full read/write access to your CRM with your API key. Open an issue if you need a hosted setup.

2d. Cursor IDE

1. Open Settings (Ctrl+,) → search "MCP"
2. Edit MCP Servers JSON, or add mcp.json in project root / .cursor/

Option A — local project (after npm run build):

{
  "mcpServers": {
    "propstack": {
      "command": "node",
      "args": ["./dist/index.js"],
      "cwd": "C:/Users/you/path/to/propstack_mcp",
      "env": {
        "PROPSTACK_API_KEY": "your_api_key_here"
      }
    }
  }
}

Or use .env in project root — the server loads it automatically; you can omit the env block.

Option B — npx (published package or npx from local):

{
  "mcpServers": {
    "propstack": {
      "command": "npx",
      "args": ["-y", "propstack-mcp-server"],
      "env": {
        "PROPSTACK_API_KEY": "your_api_key_here"
      }
    }
  }
}

2e. Run directly

npm install propstack-mcp-server
PROPSTACK_API_KEY=your_key npx propstack-mcp-server

API Key / API-Schluessel

Get your Propstack API key:

1. Log in to crm.propstack.de
2. Go to Verwaltung > API-Schluessel (Administration > API Keys)
3. Create or copy your V1 API key

Hinweis: Der API-Schluessel bestimmt die Berechtigungen. St
