@giltiq/mcp

MCP server for EU VAT validation with multi-source reliability (VIES + Germany's BZSt), automatic failover, and legally binding qualified confirmations per §18e UStG. Works when VIES is down. No other MCP server provides this.

Install

npx @giltiq/mcp

Related MCP server: vies-smoother

Configure

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "giltiq": {
      "command": "npx",
      "args": ["-y", "@giltiq/mcp"],
      "env": {
        "GILTIQ_API_KEY": "gq_live_your_key_here"
      }
    }
  }
}

Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "giltiq": {
      "command": "npx",
      "args": ["-y", "@giltiq/mcp"],
      "env": {
        "GILTIQ_API_KEY": "gq_live_your_key_here"
      }
    }
  }
}

Windsurf

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

{
  "mcpServers": {
    "giltiq": {
      "command": "npx",
      "args": ["-y", "@giltiq/mcp"],
      "env": {
        "GILTIQ_API_KEY": "gq_live_your_key_here"
      }
    }
  }
}

No API key? The server works without one in anonymous mode (10 free validations, VIES only). Set GILTIQ_API_KEY to unlock 100 calls/month, qualified confirmations, and usage tracking.
