Email Deliverability MCP Server

Report whether a seed-list inbox-placement provider is connected for the org, which provider, and how many tests have run. Lists the supported providers when not connected.

Poll a seed-list inbox-placement test by testId. Returns status (running/completed/failed) and, once measured, the Inbox/Spam/Missing counts and inbox-placement score (0–100). Call after sending your campaign to the seed addresses from start_inbox_placement_test.

List recent seed-list inbox-placement tests for the org (most recent first) with their status and Inbox/Spam/Missing scores.

Poll an async batch scan started with scan_domains_batch: returns status (queued/running/succeeded/partial/failed), completed count, and per-domain results (domain, ok, score, grade) as they finish.

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. Runs at your plan tier (full blocklist set on paid plans) and saves the scan to the domain history in your account.

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.

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.

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.

Return a structured deliverability report for a tracked domain: the latest score + letter grade, each check's status (pass/warn/fail), 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.

Return the overall deliverability score and letter grade for a domain (runs a fresh scan).

Full detail for one tracked domain: the domain record, the latest scan with all per-check findings (spf, dmarc, dkim, ptr, mta_sts, tls_rpt, mx_tls, blocklist), recent score history, open/recent alerts, and Google Postmaster stats when connected.

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.)

Return the latest per-IP reputation from Microsoft SNDS for the org's sending IPs: filter result (GREEN/YELLOW/RED), complaint-rate band, spam-trap hits, message volume, and current block status. Requires SNDS to be connected (see connect_snds / get_snds_status).

Report whether Microsoft SNDS is connected for the org, the last sync time + status, how many sending IPs are tracked, and how many are currently blocked by Outlook/Hotmail. Use before get_snds_ip_stats to confirm the integration is live.

List the account's deliverability alerts (score drops, check failures, blocklist listings). Defaults to open alerts only.

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 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 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).

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.

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.

List the account's tracked domains with latest scan score, last scan time, and open alert count.

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.

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.

List the registrar accounts (Cloudflare, Route 53, GoDaddy, Namecheap) connected to the org — provider, verification, last-used time — plus the supported providers. Use this to check whether the detect-and-fix loop (get_dns_fix_plan / apply_dns_fix) is available before attempting it.

Mark an alert resolved (or reopen it with resolved=false). Requires an API key with write/full scope. Resolving an already-resolved alert is a no-op.

List recent scans (id, domain, run time, score) across all tracked domains, or for one domain when a name is given.

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.

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.
