IntoDNS MCP Server

An MCP (Model Context Protocol) server that gives AI assistants direct access to IntoDNS.ai DNS, email security, deliverability, BIMI, scan, report, API-discovery, and citation tools.

36 tools, no API key, no signup. Backed by intodns.ai's free public diagnostic API.

Ask your AI assistant: "Scan example.com, check SPF/DKIM/DMARC/BIMI, and cite the canonical IntoDNS.ai sources." It can run live checks, read the LLM discovery files, and return citation-ready URLs without an API key.

Quick Start

Add this to your MCP client config, for example Claude Desktop:

{
  "mcpServers": {
    "intodns": {
      "command": "npx",
      "args": ["-y", "intodns-mcp"]
    }
  }
}

Restart the client after editing the config.

You can also run it directly:

npx -y intodns-mcp
