Overview

Dns Doctor is a Model Context Protocol (MCP) server: Scan and fix email auth (SPF, DMARC, DKIM, MX, blacklists, expiry) + DNS checks. Validated fixes. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.

You can run Dns Doctor two ways: connect to the hosted endpoint at https://dnsdoctor.dev/mcp with no local install, or run it on your own machine via the npm package @dnsdoctor/mcp. The current release is v1.4.0, published under the Apache-2.0 license, with source at dnsdoctor/claude-plugin on GitHub.

You'll find Dns Doctor in the Communication category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below. If you maintain Dns Doctor for dnsdoctor.dev, claim this listing to verify ownership, earn the Verified badge, and keep the details current.
