Palisade DMARC Agent

@palisadeemail/mcp

Connect an MCP client to the Palisade MCP server, which monitors and manages email authentication (SPF, DKIM, DMARC, MTA-STS, BIMI) for your domains.

Palisade's MCP server is remote (Streamable HTTP at https://api.palisade.email/mcp). This package is a thin local bridge for stdio-based clients, using mcp-remote under the hood. Clients that support remote HTTP MCP servers with a bearer token can point at the URL directly and skip this package.

Get an API key

Create one at app.palisade.email → Settings → API keys, or programmatically via headless signup. See the developer guide.

Use it

Set PALISADE_API_KEY and run:

PALISADE_API_KEY=secret_... npx -y @palisadeemail/mcp

Client config (stdio)

{
  "mcpServers": {
    "palisade": {
      "command": "npx",
      "args": ["-y", "@palisadeemail/mcp"],
      "env": { "PALISADE_API_KEY": "secret_..." }
    }
  }
}

Direct (clients that support remote HTTP MCP)

{
  "mcpServers": {
    "palisade": {
      "type": "http",
      "url": "https://api.palisade.email/mcp",
      "headers": { "Authorization": "Bearer secret_..." }
    }
  }
}

When headers.Authorization is set, the client authenticates with that API key and does not fall back to OAuth. The server replies 401 with a WWW-Authenticate challenge whenever credentials are missing or rejected, so a bad key surfaces as a connection error rather than silently starting an OAuth flow.

If the server connects but the Palisade tools are missing

A session that offers only authenticate / complete_authentication is using an OAuth-based entry, not your API-key entry. The Palisade server has no reduced tool set: any authenticated caller gets the full list under Tools. Those two tools come from the client's own pending-OAuth state.

This usually means a same-named server is configured somewhere else and is the one in effect. In Claude Code, --scope local applies only to the directory it was run in, and a palisade entry in user scope (from a previous OAuth connection) applies everywhere else. Check which entry actually wins:

claude mcp get palisade

The reported scope is the one in effect. If it is not the entry holding your API key, remove the other one, for example claude mcp remove palisade -s user, or give the API-key entry a distinct name.

Tools

Accounts (get_account), domains (list_domains, get_domain, add_domain, remove_domain, verify_domain), DNS setup (get_dns_records — the exact records to publish at your own DNS provider), MTA-STS (get_mta_sts, enable_mta_sts), remediation tasks (list_tasks, get_task), groups (list_groups), and billing (get_subscription, start_checkout, get_billing_portal_url).

Palisade tells you which DNS records to publish; you apply them at whatever DNS provider hosts the domain. Payment happens on Stripe-hosted pages.

Environment

• PALISADE_API_KEY (required) — your Palisade API key.
• PALISADE_MCP_URL (optional) — override the server URL (defaults to https://api.palisade.email/mcp).
