Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.

Is inboxguard free to use?

Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.

api record

InboxGuard tools cover deliverability scanning AND the authenticated product end to end. Deliverability scanning: scan_domain (renders an interactive scorecard ui://inboxguard/scan-result), get_deliverability_score, check_blocklists, analyze_headers (re-verify SPF/DKIM/DMARC/ARC on a raw email), scan_domains_batch + get_scan_job (async batch of up to 50). Every tools/call requires an API-key bearer token — for a keyless one-off scan, POST to the REST endpoint /scan-domain (5/hour per IP). With an API key, scans run at the org's plan tier and auto-track the domain; account tools: list_domains,…

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

start_inbox_placement_test auth-required never probed
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.

arguments 9 lines

analyze_headers reads auth-required 18h ago

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.

get_dmarc_summary auth-required 25h ago

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.

scan_domain reads auth-required 4h ago
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.

mcp-tool

get_inbox_placement_status reads auth-required 6h ago
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.

mcp-tool
{ "type": "object", "properties": {} }
arguments 4 lines
get_deliverability_report reads auth-required 4h ago
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.

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

apply_dns_fix changes data auth-required never probed

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.

scan_domains_batch reads auth-required never probed
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.

arguments 17 lines
remove_domain changes data auth-required never probed
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.)

list_registrar_connections reads auth-required 15h ago
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.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 760c5aa1f98c8500.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/760c5aa1f98c8500/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
