Best DMARC software for AI agents

The best DMARC software for an AI agent is a tool your assistant's own connector can reach. PowerDMARC's docs name all four assistants below, behind an Enterprise or MSP plan; DMARCwise names three; Palisade is documented for Claude and Microsoft 365 Copilot and has a read-only ChatGPT plugin. Every tool here has an MCP server, but ChatGPT and claude.ai connect only to remote servers and prefer OAuth; Microsoft 365 Copilot's MCP plugins do not accept API keys; Grok's consumer app rejects local servers. Below, each tool is checked twice: what its vendor documents, and what each assistant's own docs say it can reach.

Methodology

How we compared the field

One method, applied to every vendor

Each row is one of the 14 DMARC MCP servers on our MCP server roundup. Transport, sign-in, write scope and cost come from the same vendor-sourced records that page uses.Source

For each assistant we read the assistant's own documentation on 28 October 2026: OpenAI's help center and Apps SDK, Anthropic's connector and Claude Code docs, xAI's Grok connector, Grok Build and API docs, and Microsoft's Copilot Studio, Microsoft 365 Copilot and VS Code docs.Source 1, Source 2, Source 3, Source 4

Then we read each vendor's MCP docs for the assistants it names. A cell says Documented or Named when the vendor's own page names that assistant; Compatible when the vendor does not, but its documented transport and sign-in match what the assistant accepts; Not yet or Not directly when either side's docs rule it out; Not disclosed by vendor when the vendor's docs do not describe a route the assistant accepts.

Compatible means the documentation on both sides lines up. We did not sign up for each product and connect each assistant, so treat it as a strong lead rather than a tested result.

Copilot covers Microsoft Copilot Studio, Microsoft 365 Copilot and GitHub Copilot in VS Code. The consumer Microsoft Copilot app is left out: Microsoft lists only fixed connectors for it, with no custom MCP servers.Source

Grok covers grok.com connectors, the xAI API and the Grok Build CLI. ChatGPT means the ChatGPT apps; OpenAI's Codex CLI is noted where a vendor documents it.

Palisade is listed first because this is Palisade's roundup. The rest are ordered by how many of the four assistants their own docs name, then by the MCP roundup's order.

Where a vendor does not publish something, this page says so rather than inferring it.

Evaluation criteria

  • ChatGPT. Whether ChatGPT can add the server as a custom connector.

The field

The best DMARC software for AI agents, by assistant

01

Palisade

Our platformFrom $19/mo; 15-day trial

Documented for Claude and Microsoft 365 Copilot, with a read-only ChatGPT plugin; records at your DNS provider are published only after approval in the Palisade app.

Palisade publishes setup for claude.ai, Claude Code, Codex CLI, Cursor, Windsurf, a read-only ChatGPT plugin and a tenant-installed Microsoft 365 Copilot agent. The assistant reads reports, tickets and DNS evidence and returns the exact records to publish. It can adjust the DMARC and SPF records Palisade hosts, but no MCP tool writes at your DNS provider; approved records are published from the Palisade app.

Best for

Teams that want one DMARC agent across Claude, Microsoft 365 Copilot and ChatGPT

Key features

  • Microsoft 365 Copilot agent, installed by your tenant admin
  • One public OAuth client, with PKCE and no secret
  • npm stdio bridge for Codex, Cursor and Windsurf
  • Read-only ChatGPT plugin for monitoring and diagnosis
  • MCP included on every plan

ChatGPT

A ChatGPT plugin you add from ChatGPT's Plugins page. Palisade supports ChatGPT through a custom MCP connection to https://api.palisade.email/mcp/directory for read-only monitoring and diagnosis. This connection requires an account with exactly one active Palisade organization. Palisade is not yet listed in the OpenAI app directory; directory availability is separate from ChatGPT support.

Claude

Steps for claude.ai custom connectors and a Claude Code command, both through Palisade's public OAuth client.

Grok

Not documented by Palisade. Grok Build runs stdio servers, the route Palisade's npm bridge already uses for Codex, Cursor and Windsurf.

Copilot

A Microsoft 365 Copilot agent your tenant admin installs; it is not in the public Agent Store, and access follows your Copilot licensing.

Transport

Streamable HTTP, plus a published npm bridge for stdio-only clients

Auth

MCP requires OAuth through Palisade's public connector client (ryKtuiPypMeYMoL1Cmhxtz6BYrEYQbLV), using PKCE with no client secret. Sign in and select your organization. API keys and self-registered OAuth clients are not accepted on the MCP endpoint; API keys remain available for the REST API.

Choose Palisade if Your people are split across Claude and Microsoft 365 Copilot, with the ChatGPT plugin for read-only checks, and you want records at your DNS provider published only after a person approves them.

Questions

Frequently asked questions

Which DMARC software works with ChatGPT?

PowerDMARC, DMARCwise, DMARKOFF, DMARCEye and Palisade publish ChatGPT setup, and Authwright and Cloudflare name ChatGPT without steps. ChatGPT connects only to remote servers and does not take a custom API key, so key-only servers such as Report URI's say ChatGPT cannot connect yet. Full read and write custom connectors are on ChatGPT Business and Enterprise/Edu; OpenAI lists Pro as read and fetch only.

All 14 on this page. claude.ai custom connectors reach remote servers with OAuth or no sign-in (header sign-in is a beta for a limited set of organizations), and are open on every plan, with one custom connector on Free. Claude Desktop and Claude Code also run local stdio servers, which is how DMARC Report and Parse DMARC connect. Source (2026-10-28) Source 2 (2026-10-28) Source 3 (2026-10-28)

Can Grok connect to DMARC software?

Yes, through any of three routes: custom connectors on grok.com (public URLs only; on Business and Enterprise an admin adds them first), the xAI API's remote MCP tools (Streamable HTTP or SSE with an authorization token), and the Grok Build CLI, which also runs local stdio servers and opens a browser for OAuth. Among DMARC vendors only PowerDMARC publishes Grok setup, for a Grok Desktop config file that xAI's own docs do not describe. For the rest, the Grok column shows where the documented connection types match. Source (2026-10-28) Source 2 (2026-10-28) Source 3 (2026-10-28) Source 4 (2026-10-28)

Which DMARC software works with Microsoft Copilot?

It depends on which Copilot. Copilot Studio takes Streamable HTTP servers with no sign-in, an API key or OAuth; PowerDMARC and DMARCwise document it. Microsoft 365 Copilot's MCP plugins take OAuth or Entra sign-in but not API keys; Palisade offers a Microsoft 365 Copilot agent your tenant admin installs. GitHub Copilot in VS Code runs local and remote servers; PowerDMARC documents it. The consumer Copilot app has no custom MCP servers.

Is GPTBot an AI agent that uses DMARC tools?

No. GPTBot is OpenAI's crawler for training data; blocking it in robots.txt says your content should not be used for training. It does not call tools or MCP servers. When a ChatGPT user connects a DMARC tool, ChatGPT itself calls that tool's MCP server. Source (2026-10-28)

Does an AI agent connected to DMARC software change my DNS on its own?

Only if the server has a tool that writes DNS and you let it run. Only Authwright and Cloudflare have MCP tools that write at your DNS provider. Palisade, DMARCwise and Red Sift can change records they host for you; Palisade publishes records at your own DNS provider only from its app, after you approve them. ChatGPT can also ask for confirmation before a connector's write actions. Source (2026-10-28)

What makes a DMARC MCP server work with the most AI assistants?

A remote Streamable HTTP endpoint with OAuth sign-in. Every assistant surface on this page accepts that combination, though on the xAI API you supply the token yourself. API-key-only servers miss ChatGPT and Microsoft 365 Copilot's MCP plugins, and local stdio servers cannot reach ChatGPT or grok.com without a tunnel.

How is this list ranked?

This is Palisade's roundup, so Palisade appears first and we are transparent about that. The other vendors are ordered by how many of the four assistants their own docs name. Each cell carries its source and the date we checked it. The page covers which assistants can connect to each DMARC tool, not which tools use AI inside the product.
