Installation

  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/dev.workers.mike-tusa.mailalign%2Fmailalign/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

Reports From / Return-Path / Reply-To / DKIM d= alignment (relaxed and strict), SPF / DKIM / DMARC / ARC verdicts as recorded by the receiving servers (Authentication-Results, ARC-*), the Received hop chain oldest first with per-hop delays and public IPs, and plain-English findings with severity and what each means or how to fix it. Makes no network or DNS calls and does not verify signatures. Header text is not stored. Read-only. Same engine as the MailAlign JSON API (POST /api/analyze).

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
