このMCPでできること

Scans and monitors domain email deliverability, including SPF, DKIM, DMARC, DNS blocklists, inbox placement, reputation, alerts, and guided DNS fixes.

analyze_headers

Analyze raw email headers

Re-verify SPF, DKIM, DMARC, and ARC from a raw RFC 5322 email (full message or just the headers block). Returns InboxGuard's independent verdict (`ours`), the sender's own Authentication-Results (`theirs`), whether they `agree`, and parsed envelope/headers — useful for spotting forged or mismatched auth results. No account needed.

apply_dns_fix

Apply the DNS fix plan

Apply a DNS fix plan to a tracked domain by publishing records at the connected registrar. DESTRUCTIVE: it creates/updates/deletes DNS records. Two-step by design — first call get_dns_fix_plan, then pass its `connectionId` and `ops` here verbatim. The server re-derives the diff from the latest scan and rejects any op that no longer matches, so an agent can never apply arbitrary records. Requires an owner/admin API key with write or full scope. Re-scan afterward to confirm the fix.

check_blocklists

Check DNS blocklists

Check a domain (apex + MX-host IPs) against supported DNS blocklists and return listings, targets checked, and issues (authoritative-side queries; no public-resolver false positives).

connect_inbox_placement

Connect an inbox-placement provider

Store the org's seed-list inbox-placement provider + API key (provider: 'mailreach' or 'glockapps'; GlockApps also needs projectId). Enables start_inbox_placement_test. Requires an owner/admin API key with write or full scope.

connect_snds

Connect Microsoft SNDS

Store this org's Microsoft SNDS (Smart Network Data Services) automated-data-access key so InboxGuard syncs per-IP Outlook/Hotmail reputation daily. Get the key from the SNDS Automated Data Access page (https://sendersupport.olc.protection.outlook.com/snds/). Requires an owner/admin API key with write or full scope. Data appears within ~24h of the first sync.

create_notification_channel

Create a notification channel

Create a channel that InboxGuard alerts are delivered to: webhook (HMAC-signed), Slack, Microsoft Teams, PagerDuty, SMS, or email. Returns the channel id, and for kind=webhook the `signing_secret` used to verify deliveries. Requires an owner/admin API key with write or full scope.

create_share_link

Create a public share link

Create a read-only public share link for a tracked domain's latest report (anyone with the URL can view it; no account). Returns a `token` and the public `url` (https://inboxguard.io/r/<token>). Requires an owner/admin API key with write or full scope, on a plan that includes public reports.

入力スキーマ

{'type': 'object', 'required': ['domain'], 'properties': {'domain': {'type': 'string', 'description': 'Domain name tracked in the account, e.g. example.com.'}}}

get_deliverability_report

Get a deliverability report

Return a structured deliverability report for a tracked domain: the latest score + letter grade + `scoreSubtitle` (explains the denominator when a check was excluded, e.g. "80/100 · scored on 65 of 83 applicable points · 1 check unverified"), each check's status (pass/warn/fail/unverified/not_applicable — `not_applicable` means the check doesn't apply to this domain and `unverified` means it couldn't be checked this scan; neither is a failure), the top issues to fix, blocklist count, and DMARC policy. Includes `pdfUrl` — the same auth-gated endpoint that returns a branded one-page PDF (send your bearer token). Use this to summarize a domain's posture or hand a client a report.

get_dmarc_summary

Get DMARC summary

Summarize ingested DMARC aggregate (RUA) reports for a domain tracked in your InboxGuard account: report volume, pass rate, top sending sources, and the rua inbox to publish. The domain must already be added to the account, and the plan must include DMARC ingest.

get_dns_fix_plan

Preview the DNS fix plan

Compute the exact DNS-record changes needed to fix a tracked domain's deliverability, based on its latest scan and the org's connected registrar (Cloudflare/Route 53/GoDaddy/Namecheap). Read-only — nothing changes. Returns the `ops` to pass verbatim to apply_dns_fix, plus `manualReview` items that need a human decision (SPF sender list, DKIM keys, BIMI logo). Requires the domain to be tracked, a scan to exist, and a registrar connection covering the zone.

Org-wide deliverability rollup across every monitored domain: average score + overall grade, the grade distribution (how many domains are A/B/C/D/F/unscored), total open alerts, the domains needing attention (lowest score / open alerts first), and a per-client-group breakdown. Use this for an at-a-glance portfolio health summary across an agency or multi-domain account.

remove_domain

Remove a monitored domain

Stop monitoring a domain and delete it (and its scan history) from the account. DESTRUCTIVE and not reversible. Requires an owner/admin API key with write or full scope. (To ADD a domain, run scan_domain with this API key — authenticated scans auto-track the domain.)

scan_domain

Scan domain deliverability

Run a full email-deliverability scan (SPF, DKIM, DMARC, MTA-STS, TLS-RPT, MX TLS, BIMI, DNS blocklists) for a domain and return a 0-100 score with per-check findings. A check can come back `not_applicable` (does not apply to this domain, e.g. MTA-STS on a domain with no MX — excluded from the score, not a failure) or `unverified` (could not be determined this scan, e.g. DKIM behind an ESP with a random per-tenant selector like Amazon SES Easy DKIM — never treat as a failure). `scoreSubtitle` explains the denominator when anything was excluded. Runs at your plan tier (full blocklist set on paid plans) and saves the scan to the domain history in your account.

scan_domains_batch

Batch-scan domains (async)

Queue an asynchronous batch scan of up to 50 domains and get a jobId immediately (avoids the 30s per-call limit). Poll get_scan_job with the jobId until status is succeeded/partial/failed to read per-domain scores. Requires an API key with write or full scope. These scans are NOT added to monitoring or saved to history.

start_inbox_placement_test

Start an inbox-placement test

Start a seed-list inbox-placement test. Returns a testId, the seed addresses to mail your campaign to, and (if the provider requires it) a header to insert. After sending to the seeds, poll get_inbox_placement_test for the Inbox/Spam/Missing verdict. Requires inbox-placement to be connected and an owner/admin API key with write or full scope.
