MCP Setup Guide

Connect Claude Desktop to The Veil in 2 minutes

1

Get your API keys

You need two keys: your DSA API key (from The Veil) and your Anthropic API key (from console.anthropic.com). If you don't have a DSA key yet, sign up at /account/signup.

2

Open Claude Desktop settings

In Claude Desktop, go to Settings → Developer → Edit Config. This opens your claude_desktop_config.json file.

3

Add the MCP server

Paste the configuration below into your claude_desktop_config.json file. Replace the placeholder values with your actual keys.

4

Restart Claude Desktop

Close and reopen Claude Desktop. You should see "theveil" in the MCP servers list. Every message you send now routes through The Veil's privacy pipeline.

claude_desktop_config.json
{
  "mcpServers": {
    "theveil": {
      "command": "npx",
      "args": ["-y", "@theveil/mcp-server"],
      "env": {
        "DSA_GATEWAY_URL": "https://gateway.dsaveil.io",
        "DSA_API_KEY": "<your DSA API key>",
        "ANTHROPIC_API_KEY": "<your Anthropic API key>"
      }
    }
  }
}

How it works

  • Every message is scanned for PII (names, emails, addresses, medical terms) before it reaches the LLM.

  • Detected PII is replaced with safe placeholders. The LLM never sees real personal data.

  • Responses are re-linked: placeholders are swapped back to the original values before you see them.

  • A Veil Certificate is generated for each request — cryptographic proof of what was sanitized.
