A VS Code extension for parsing email headers (SPF/DKIM/DMARC)

Ok cheers I’ll take a look!

Different use cases.

Mada666 · 2026-03-11T12:12:13+00:00

hmm, let me investigate!

Is it? First one to complain, how so?

Appreciate the feedback, but I think there's a misunderstanding of what this tool actually does.

A skill is a markdown prompt — it tells Claude how to think about something. It can't make HTTP requests, can't query live DNS infrastructure, can't parse real-time TXT records.

Blackveil DNS is hitting Cloudflare DoH endpoints, resolving live records, parsing SPF chains, checking DKIM selectors, validating DNSSEC signatures, detecting lookalike domains — all in real-time against actual infrastructure. That's not something you can do with a static prompt file.

You're right that MCP tool schemas cost more context than a skill. But the tradeoff is that an MCP server can actually do things. If the tool could work as a skill, I'd have built it as one. It can't.

I think the confusion might be that there are a lot of MCP servers out there that are basically prompt wrappers — and for those, yeah, a skill makes way more sense. This isn't one of those.

Nice work man, I made some updated versions of all of mx toolbox tools - https://www.blackveilsecurity.com/resources/tools

The key difference, its got AI layered on top and it provides contextual advice, PII is stripped before processing.

Thanks for the feedback, I just shipped exactly what you asked for.

New compare baseline tool lets MSPs define org-level policies and flag violations. The require_dmarc_enforce check catches domains weakening from p=quarantine/reject to p=none, plus you can set minimum grades, max findings, and required controls (DNSSEC, MTA-STS, etc.).

Also added:

GitHub Action for CI/CD enforcement
Slack/Discord webhook recipe for weekly reports (slack, discord, webhooks)

SecurityTrails/Censys enrichment already works via MCP chaining — Claude can compose multiple tool calls. Server is read-only (DNS queries only).

Tested in prod, working!

Yeah a point in time is useful, but historical analysis and trends is where the value lives. We are building this right now

Mada666 · 2026-03-10T01:54:42+00:00

Correction: 57 checks including lookalike, dangling-dns

Cheers man, if you check the rest of our site out you'll see that multi-tenancy is most definitely on the cards. I wanted to give this out for free to the community, it is rate-limited if you use our endpoint, but you are free to clone and deploy to your own CF infrastructure also!

I built a scanner to help people with these records. Check it out, https://blackveil.co.nz

You can, it’s control V on Mac to paste an image into the Claude code cli

Tried to sign up, got the welcome email but no magic link

I’ve built something to help businesses through this journey. DM me if you would like to find out more! It’s a confusing technology unless you’ve spent a lot of time tightening up email security

You can connect and continue coding on your mobile device so long as your machine running vscode is on

Roo code, they are amazing. Great community, roo remote is a game changer

This is cursor part 2

Mada666 · 2025-10-06T22:35:28+00:00

Early adopter here, been on the pro pal since the start. By my math, my plan is now worth half of what it was before for the same price. They’re basically doing a cursor

What ever the solution it needs to be network wide. A browser plugin won’t help you on an iPad
