Overview

Deliverability Doctor is a Model Context Protocol (MCP) server: Check if a domain can be email-spoofed: SPF, DMARC, DKIM, MX graded from public DNS. Authless. In practice that means any MCP-compatible AI assistant can call Deliverability Doctor's tools directly — the model decides when to use them in a conversation or agent run.

It's a hosted (remote) server — point your client at https://deliverability-doctor.deliverability-doctor.workers.dev/mcp and you're connected, with nothing to install locally. The current release is v1.0.2, published under the MIT license, with source at Integrity-Os/deliverability-doctor on GitHub.

Deliverability Doctor is listed under Communication on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below. If you maintain Deliverability Doctor for Integrity-Os, claim this listing to verify ownership, earn the Verified badge, and keep the details current.
