Data source: Polish national RCN registry (Rejestr Cen Nieruchomosci) | Platform: cenogram.pl

Get your API key

Go to cenogram.pl/api
Enter your email
You'll receive your cngrm_... API key by email

Manage your keys at cenogram.pl/ustawienia.

Installation

Pick your client. All options below use the hosted server - no local install needed (except npx/stdio).

Claude Code

One command - zero config files:

claude mcp add cenogram https://mcp.cenogram.pl/mcp \
  -t http -H "Authorization: Bearer YOUR_API_KEY"

Cursor

Add to .cursor/mcp.json in your project:

{
  "mcpServers": {
    "cenogram": {
      "type": "http",
      "url": "https://mcp.cenogram.pl/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Claude Desktop

Add to your config file:

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

npx (stdio):

{
  "mcpServers": {
    "cenogram": {
      "command": "npx",
      "args": ["-y", "@cenogram/mcp-server@latest"],
      "env": {
        "CENOGRAM_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}

VS Code / GitHub Copilot

Add to .vscode/mcp.json in your workspace:

{
  "servers": {
    "cenogram": {
      "type": "http",
      "url": "https://mcp.cenogram.pl/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

HTTP remote:

{
  "mcpServers": {
    "cenogram": {
      "type": "http",
      "url": "https://mcp.cenogram.pl/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

If HTTP doesn't work, use the npx (stdio) option below instead.

Cline

In VS Code: Settings > Cline > MCP Servers. Add:

{
  "cenogram": {
    "type": "http",
    "url": "https://mcp.cenogram.pl/mcp",
    "headers": {
      "Authorization": "Bearer YOUR_API_KEY"
    }
  }
}

npx (stdio) - local/offline

Requires Node.js >= 18. Use this if you want to run the server locally instead of connecting to the hosted one.

{
  "mcpServers": {
    "cenogram": {
      "command": "npx",
      "args": ["-y", "@cenogram/mcp-server@latest"],
      "env": {
        "CENOGRAM_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}
