What your AI can do with MailVakt
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “diagnose_domain”: Audit a domain's SPF, DKIM, DMARC, MX, alignment, BIMI, MTA-STS and TLS-RPT configuration when troubleshooting email authentication or spam.”
“Use “analyze_email_headers”: Analyze raw email headers supplied by the user to investigate authentication or delivery issues. Returns the SPF, DKIM and DMARC results rep.”
“Use “generate_dns_records”: Propose email-authentication DNS records and policy files for a domain using its DNS configuration and optional provider names or IDs. Suppo.”
“Use “start_inbox_test”: Create an email-receipt test in MailVakt. Takes an optional expected sender domain; returns a test ID, unique recipient address and expiry t.”
How secure is the MailVakt MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how MailVakt holds up.
Official endpoint
Operated by MailVakt (mailvakt.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If MailVakt adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

The MailVakt MCP server at a glance
https://mcp.mailvakt.com/mcpQuestions, answered
Is there an official MailVakt MCP server?
Yes — MailVakt operates its own remote MCP server at mcp.mailvakt.com. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect MailVakt to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick MailVakt in the directory. No account or sign-in is needed. From then on, MailVakt's tools are available in every client you've connected to gate.
Do I need to host anything?
No. MailVakt runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the MailVakt MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect MailVakt in minutes. No credit card required.
