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

Go to Settings > Connectors > Developer Mode
Add a new MCP connector
Set the command to npx -y propstack-mcp-server
Add environment variable PROPSTACK_API_KEY

2d. Cursor IDE

Open Settings (Ctrl+,) → search "MCP"
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
