Overview

AI-generated overview

Remote MCP server that creates temporary email addresses and returns deliverability reports on a test message: SPF, DKIM, DMARC, TLS, IPv6 and sender rules.

What you can do
  • Create a temporary echo.email test address and get back a token and key
  • Wait for the email sent to that address to be analysed, polling until a digest is ready
  • Fetch the finished report as JSON with the digest plus every check: SPF trace, DKIM, DMARC, BIMI, TLS, IPv6, images, links, unsubscribe, headers and DNS log
When to use it
Use it when you need to verify that outgoing email from a system under test authenticates and passes common sender requirements, for example after changing DNS records or mail configuration. It suits quick, one-message checks rather than ongoing monitoring.
Requirements
A remote MCP endpoint; no package, API key, environment variable or header is declared. The workflow needs the ability to send one real email from the system under test to the generated address, and the test address expires after 10 minutes without a wait_for_report call.
Before you install
The test address accepts one message and dies after 10 minutes without a wait_for_report call, so timing matters. The email content is sent to a third-party service for analysis, so avoid including sensitive data in the test message. No authentication is declared.

Installation

In SourceWeft

  1. Open echo.email Deliverability Test in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in 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/email.echo%2Fdeliverability/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
