Cenogram - Polish Real Estate Prices & Parcel Data MCP server

Cenogram MCP Server

Polish Real Estate Transaction & Parcel Data for AI

MCP server for Polish real estate data. Access 8M+ real estate transactions from the national Registry of Prices and Values (Rejestr Cen Nieruchomosci, RCN) - prices from notarial deeds, not listings - directly from Claude, Cursor, ChatGPT, Grok, or any MCP-compatible AI assistant. Beyond transaction prices, the server resolves cadastral parcels and adds per-parcel context: zoning, flood and landslide risk, heritage register, building permits and construction activity, public transport access, agricultural land classification and surrounding land use.

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

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/claudedesktopconfig.json
• Windows: %APPDATA%\Claude\claudedesktopconfig.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"
      }
    }
  }
}
