Which integrations are available for this server?

Allows checking domain compliance with Gmail's sender requirements, including SPF, DKIM, DMARC, and BIMI, to improve email deliverability to Gmail. Provides tools to verify that a domain meets Google's sender requirements for email authentication and deliverability.

IntoDNS MCP Server

npm version npm downloads MCP Glama License

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
