Setup

Prerequisites

1. Get your BIM Portal credentials by registering at https://via.bund.de/bim
2. Install Node.js and npm

Adding to Cursor

1. Open Cursor Settings (Cmd/Ctrl + ,)
2. Search for "MCP" in settings
3. Click "Edit in settings.json" next to "Mcp: Servers"
4. Add the BIM Portal MCP server configuration:

{
  "mcp.servers": {
    "bim-portal": {
      "command": "npx",
      "args": ["-y", "bim-portal-mcp"],
      "env": {
        "BIM_EMAIL": "[email protected]",
        "BIM_PASSWORD": "your-bim-portal-password"
      }
    }
  }
}

Note: If you're using nvm and experiencing Node.js version conflicts, use the absolute path and clean PATH:

{
  "mcp.servers": {
    "bim-portal": {
      "command": "/path/to/your/node/version/bin/npx",
      "args": ["-y", "bim-portal-mcp"],
      "env": {
        "BIM_EMAIL": "[email protected]",
        "BIM_PASSWORD": "your-bim-portal-password",
        "PATH": "/path/to/your/node/version/bin:/usr/local/bin:/opt/homebrew/bin:/usr/bin:/bin:/usr/sbin:/sbin"
      }
    }
  }
}

5. Save the settings file
6. Restart Cursor
7. The BIM Portal tools will now be available in your AI conversations

Adding to Claude Desktop

1. Locate your Claude Desktop configuration file:

   • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
   • Windows: %APPDATA%\Claude\claude_desktop_config.json

2. Edit the configuration file and add the MCP server:

{
  "mcpServers": {
    "bim-portal": {
      "command": "npx",
      "args": ["-y", "bim-portal-mcp"],
      "env": {
        "BIM_EMAIL": "[email protected]",
        "BIM_PASSWORD": "your-bim-portal-password"
      }
    }
  }
}

Note: If you're using nvm and experiencing Node.js version conflicts, use the absolute path and clean PATH:

{
  "mcpServers": {
    "bim-portal": {
      "command": "/path/to/your/node/version/bin/npx",
      "args": ["-y", "bim-portal-mcp"],
      "env": {
        "BIM_EMAIL": "[email protected]",
        "BIM_PASSWORD": "your-bim-portal-password",
        "PATH": "/path/to/your/node/version/bin:/usr/local/bin:/opt/homebrew/bin:/usr/bin:/bin:/usr/sbin:/sbin"
      }
    }
  }
}

3. Save the file
4. Restart Claude Desktop
5. The BIM Portal tools will be available in your conversations

Environment Variables (Alternative)

Instead of putting credentials in the config file, you can set environment variables:

export BIM_EMAIL="[email protected]"
export BIM_PASSWORD="your-bim-portal-password"

Then use this simplified configuration:

{
  "mcpServers": {
    "bim-portal": {
      "command": "npx",
      "args": ["-y", "bim-portal-mcp"]
    }
  }
}

BIM Portal API

This server connects to the German Federal BIM Portal at https://via.bund.de/bim and provides access to:

• Infrastructure elements and properties
• Building Information Modeling data
• Level of Information Need (LOIN) specifications
• Domain-specific models
• AIA (Client Information Requirements) templates and projects
• Construction context information

MCP Protocol

This server implements the Model Context Protocol (MCP) and communicates via stdio. It can be used with any MCP-compatible client to provide comprehensive access to the BIM Portal API functionality.

Error Handling

All API errors are properly caught and returned as error responses with descriptive messages. The server maintains authentication state and handles token refresh automatically.
