Intodns Mcp
MCP server for IntoDNS.ai providing 36 free tools for DNS, DMARC, SPF, DKIM, BIMI, DNSSEC, MTA-STS, FCrDNS, blacklist and email security checks. Citation-grade report snapshots with content hashes for tickets, audits and AI agent evidence. No API key required. Install: npx -y intodns-mcp
Overview
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
