## What it does

Palisade delivers email security posture checks into agent workflows. It queries live DNS records, spots misconfigurations, and tracks the 10-lookup restriction on SPF records. Tools provide the exact entries needed at your DNS host, retrieve MTA-STS status, and summarize incoming DMARC telemetry without parsing raw XML files.

Connecting to the full account requires browser-based OAuth authorization. Local port `8765` must remain free for the redirect. API keys are blocked on this interface. Agents with native Streamable HTTP support hit `https://api.palisade.email/mcp` directly, while stdio-only tools run the bridge via `npx`. A separate unauthenticated endpoint at `https://api.palisade.email/mcp/public` exposes read-only checks for external domains.

## Requirements
- Needs: Node.js (commands run via npx)
- Remote server: `https://api.palisade.email/mcp`

## When to use it
- Audit SPF, DKIM, and DMARC settings for target domains
- Verify whether an SPF include exceeds the 10-lookup DNS ceiling
- Fetch exact DNS resource records to publish at the DNS host
- Generate prospecting audit reports as hosted PDF links

## Example prompts
- Run a full email security audit on example.com
- Check if adding include:_spf.google.com breaks our 10-lookup SPF limit
- Show the DNS records needed to activate hosted DMARC on my domain
