01 · Install Dns (madaburns)

before you install - you'll need

BV_API_KEY

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add madaburns-bv-mcp --transport http https://dns-mcp.blackveilsecurity.com/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "madaburns-bv-mcp": {
      "url": "https://dns-mcp.blackveilsecurity.com/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
