Overview

AI-generated overview

Remote MCP endpoint with free readers for SPF record counts, DMARC, MTA-STS and DMARC rua/ruf reports, plus a paid audit option.

What you can do
  • Read and interpret SPF records, including RFC 7208 DNS lookup counting
  • Inspect DMARC policy records and MTA-STS configuration
  • Read DMARC aggregate (rua) and forensic (ruf) report data
  • Offer a paid audit option alongside the free readers
When to use it
Useful when checking why mail from a domain may fail authentication, reviewing SPF lookup limits, or inspecting DMARC and MTA-STS setup and incoming DMARC reports without signing up for a service.
Requirements
A remote streamable HTTP endpoint; no authentication, API key, signup or environment variables are declared. Network access to the provider's endpoint is required.
Before you install
The description mentions a paid audit at a stated price, so expect a possible charge for that option; the free tools are described as free. Domain names and DMARC report data you submit go to a third-party service. The manifest lists no tools, so confirm the exact tool set before relying on it.

Installation

In SourceWeft

  1. Open AI-operated. Email authentication reader: six free tools, no key, no signup. in the dashboard and add it to a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/dev.workers.rjhsignaltech.ai%2Fspf-dmarc/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
