Is tamingdns live?
Yes — it answered the hub's last check (checked 14m ago). It answered 100% of checks over the last 30 days.
Is tamingdns free to use?
Yes — the hub reached it with no key and no payment.
What tools does tamingdns have?
10 tools: check_spf, check_dnssec, check_mx, analyze_email_headers, check_dane, check_dkim, check_mta_sts, check_bimi, ….
Is tamingdns safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 10 tools

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.

  • check_spf unknown never probed

    Check the SPF record for a domain. Returns the raw record, grade (A-F), the terminal `all` qualifier (resolved through redirect= chains), structured findings (NEAR_LOOKUP_LIMIT, LOOKUP_LIMIT_EXCEEDED, PLUS_ALL_DANGEROUS, PTR_MECHANISM_DEPRECATED, etc.), and an `analysis` block with the expanded include/redirect tree and the RFC 7208 §4.6.4 lookup count. Read-only.

  • check_dnssec unknown never probed

    Validate a domain's DNSSEC chain of trust. Pulls DS (at the parent), DNSKEY, and RRSIG over binary DoH, walks the chain zone-by-zone (root → TLD → domain) recomputing each DS digest against the published DNSKEYs (RFC 4034 §5.1.4), and cross-checks the AD bit across Cloudflare, Google, Quad9, and OpenDNS so a single resolver's caching can't mask a break. Returns grade (A-F) with grade_reasons, a verdict (signed/signed_no_ds/partial/unsigned/broken), structured findings (DNSSEC_UNSIGNED, DNSSEC_DS_MISSING_AT_PARENT, DNSSEC_DS_ALGORITHM_DEPRECATED, DNSSEC_DNSKEY_ALGORITHM_DEPRECATED, DNSSEC_RRSIG_EXPIRED, DNSSEC_BOGUS, DNSSEC_AD_BIT_MISSING), and an `analysis` block (the full chain-walk, the per-resolver validator matrix, NSEC3 iteration/opt-out, CDS/CDNSKEY publication, signing mode, root-anchor state). Unsigned is the common case and returns status "info" (DNSSEC is optional), not a failure; signed_no_ds (DNSKEY published, no DS at the parent yet) is treated by validators as unsigned and also returns "info"; a published-but-non-validating zone returns "fail". Read-only.

  • check_mx unknown never probed

    Inspect a domain's MX / mail-routing posture. Resolves the apex MX RRset (priority-sorted), and for each host the A/AAAA addresses, PTR + forward-confirmed reverse DNS (FCrDNS), DANE TLSA at _25._tcp.<host>, IP-literal (RFC 5321 §5) and CNAME (RFC 2181 §10.3) violations, and the mail provider. Detects the null MX (RFC 7505), a null MX wrongly mixed with real MX, and the implicit MX via the apex A/AAAA when no MX exists (RFC 5321 §5). Probes the MTA-STS and TLS-RPT prerequisites over DNS (case-sensitive per RFC 8461/8460) with outage reported as unknown, never absence. Returns grade (A-F) with grade_reasons, a verdict (healthy/warnings/misconfigured/null_mx/no_mx/implicit_mx), structured findings (NO_MX_RECORD, MX_IMPLICIT_FALLBACK, NULL_MX, NULL_MX_WITH_OTHER, MX_POINTS_TO_IP, MX_POINTS_TO_CNAME, MX_HOSTNAME_UNRESOLVABLE, NO_PTR_RECORD, FCRDNS_MISMATCH, MX_IPV6_ONLY, MX_NO_TRANSPORT_SECURITY, MX_GATEWAY_RDNS_COSMETIC, MX_SINGLE_HOST, MX_DUPLICATE_HOST, MX_SHARED_PRIORITY, MX_MTA_STS_WITHOUT_TLS_RPT), and an `analysis` block (per-host enrichment incl. provider, ips with FCrDNS status, dane_tlsa, and the prerequisite probe results). DNSSEC AD is a UI-only signal, not gradeable through the DoH contract. Read-only.

  • analyze_email_headers unknown never probed

    Analyse a pasted block of raw email headers for spoofing and phishing tells. Input is the raw headers (everything up to the first blank line — "Show original" / "View source"); the message body is not required. Returns structured findings + a phishing verdict (likely_phishing/verify_sender/minor_concerns/legitimate/auth_incomplete) derived from SPF/DKIM/DMARC alignment (RFC 7489 §3.1), Microsoft composite-auth compauth reason codes (000/010 enforced failure, 601 intra-org implicit failure, 001 weak posture), ARC chain integrity (RFC 8617 §5.2), homoglyph / IDN look-alike From domains (Unicode UTS #39), header smuggling via duplicate singleton headers (RFC 5322 §3.6), display-name-as-address spoofing, hidden bidi/control characters (UAX #9), Received-chain timestamps running backward (RFC 5321 §4.4), link display-text-vs-href mismatches, originating-IP FCrDNS (RFC 8601), and RFC 8058 List-Unsubscribe deliverability posture (category:compliance, never moves the verdict). Findings include DMARC_FAILED, SPF_HARD_FAIL, DKIM_SIGNATURE_FAILED, COMPAUTH_EXPLICIT_FAILURE, COMPAUTH_INTRA_ORG_IMPLICIT_FAILURE, HOMOGLYPH_DOMAIN, DUPLICATE_HEADER, DISPLAY_NAME_SPOOFED_ADDRESS, RECEIVED_TIMESTAMPS_BACKWARD, URL_DISPLAY_MISMATCH, HIDDEN_CONTROL_CHAR, BRAND_IMPERSONATION, and more (registered in docs/finding-codes.md). `status` is the finding-severity aggregate; `verdict` is the authoritative phishing judgment; `analysis` carries the verdict object + per-mechanism authentication. For privacy the echoed `input` is a digest only (from / subject / message_id) — raw headers are never returned. Read-only.

  • check_dane unknown 14m ago

    Check SMTP DANE / TLSA records for a domain (RFC 7672). Resolves the MX hosts (falls back to the apex when none), looks up the TLSA record at _25._tcp.<mx-host> over binary DoH, classifies each record (usage 0-3 / selector 0-1 / matching 0-2 per RFC 7671 §2.1), and confirms the answer carried the DNSSEC AD bit — DANE is meaningless without DNSSEC, so an unsigned TLSA answer is the dominant failure mode. Returns grade (A-F) with grade_reasons, a verdict (valid/valid_with_warnings/no_dnssec/not_configured/error), structured findings (DANE_NO_TLSA, DANE_TLSA_HOST_UNSIGNED, DANE_PKIX_TA_USED_WITHOUT_CHAIN, DANE_TLSA_EXACT_MATCH, DANE_PARTIAL_COVERAGE, DANE_TLSA_INVALID_USAGE/SELECTOR/MATCHING), and an `analysis` block (per-host TLSA records + DNSSEC status, the spec-compliance signals, and the MTA-STS cross-signal). DNS-only: it never opens a port-25 STARTTLS handshake, so it proves the TLSA records exist, are well-formed, and are DNSSEC-signed — never that they match the live cert (Hostinger and Cloudflare both block outbound 25). Read-only.

  • check_dkim unknown 14m ago

    Look up a DKIM public key at <selector>._domainkey.<domain> and validate it. Detects key revocation (empty p=), RSA key length (KEY_TOO_SHORT below 1024, KEY_WEAK below 2048), SHA-1 hash deprecation, and t=y test mode. For selector1/selector2 it also checks a Microsoft 365 CNAME target carries the token Microsoft builds for the domain (M365_DKIM_CNAME_MISMATCH), even when no key resolves. Returns an `analysis` block with the per-key facts (key_type, key_bits, key_strength, revoked, test_mode, hash_algs, m365_cname). Read-only.

  • check_mta_sts unknown never probed

    Check MTA-STS (RFC 8461) for a domain: the _mta-sts TXT record (strict §3.1 selection — case-sensitive leading v=STSv1, exactly one record, required 1-32 alphanumeric id), the policy file at https://mta-sts.<domain>/.well-known/mta-sts.txt fetched WITHOUT following redirects (§3.3), strict §3.2 policy validation (version/mode/max_age required, mx required unless mode none, max_age ≤ 31557600, duplicate keys first-wins), the policy-host X.509 certificate (§3.3 — an invalid cert means compliant senders fetch no policy), and live MX coverage against the mx: patterns (§4.1 — wildcards match exactly one leftmost label; coverage is all/partial/none, partial meaning strict senders skip the uncovered hosts per §5.1). Returns grade (A-F) with grade_reasons, a verdict (enforced/testing/reporting_only/invalid/not_configured), structured findings (MTA_STS_NO_TXT_RECORD, MTA_STS_RECORD_INVALID, MULTIPLE_MTA_STS_RECORDS, MTA_STS_POLICY_UNREACHABLE, MTA_STS_POLICY_REDIRECT, MTA_STS_POLICY_INVALID, MTA_STS_CERT_INVALID, MTA_STS_MODE_NONE, MTA_STS_MODE_TESTING, MTA_STS_MX_MISMATCH, MTA_STS_MX_PARTIAL_COVERAGE, MTA_STS_MAX_AGE_TOO_LOW), and an `analysis` block (record, policy incl. fetch_stage, cert, MX coverage detail, TLS-RPT/DANE cross-signals).

  • check_bimi unknown 14m ago

    Check default._bimi.<domain>: parses the BIMI record, validates the SVG Tiny-PS logo, inspects the VMC chain (expiry, EKU, SCT, issuer-accepted, SAN match, logotype hash), and verifies the DMARC prerequisite (p=quarantine/reject at pct=100 with no sp=none — the RFC 7489 reading Gmail and Apple Mail evaluate today). DMARCbis (RFC 9989) aware: t= is parsed into analysis.dmarc.t, t=y emits TESTING_MODE (warn under p=quarantine — bis receivers read it as none; info under p=reject), and a present pct= emits DEPRECATED_TAG (removed by RFC 9989 Appendix A.6, advisory only). Returns grade (A-F), structured findings, and an `analysis` block (logo/vmc/dmarc/provider_matrix). Read-only.

  • check_dmarc unknown never probed

    Check the _dmarc record for a domain with DUAL discovery: the RFC 7489 §6.6.3 organisational-domain ladder (what major receivers enforce today — grade/verdict anchor to it) AND the RFC 9989 §4.10 DNS Tree Walk (8-query cap, psd=n/y stop rules, fewest-labels org selection) into analysis.discovery {legacy, tree_walk, diverges}. When the two methods select different policy records or org domains, DISCOVERY_DIVERGENCE (warn) fires with a one-notch grade downgrade. Also DMARCbis tag-aware: t=/np=/psd= parsed into analysis.tags, removed tags (pct/rf/ri) emit DEPRECATED_TAG, t=y emits TESTING_MODE with a one-notch downgrade. Returns the grade (A-F) with grade_reasons, a verdict (enforced/partial/monitoring/monitoring_blind/invalid/not_configured), structured findings (NO_DMARC_RECORD, MULTIPLE_DMARC_RECORDS, INVALID_TAG, POLICY_NONE, POLICY_NONE_NO_RUA, PCT_BELOW_100, RUA_MISSING_UNDER_ENFORCEMENT, SP_NOT_ENFORCED, EXTERNAL_RUA_UNAUTHORIZED, DMARC_INHERITED_FROM_ORG, TESTING_MODE, DEPRECATED_TAG, DISCOVERY_DIVERGENCE), and an `analysis` block with the lookup ladder, discovery, source (self/org), org_domain, normalised tags, per-recipient RUA/RUF external-authorisation detail (RFC 7489 §7.1), and rua_unauthorised.

  • check_tls_rpt unknown never probed

    Check the TLS-RPT (SMTP TLS Reporting, RFC 8460) record at _smtp._tls.<domain>. Strict §3 classification: the record must BEGIN with the case-sensitive v=TLSRPTv1 tag, more than one such record means receivers treat TLS-RPT as not implemented, and rua= is required. Validates every rua= destination syntactically (mailto:/https:// — reachability is never probed), and detects the MTA-STS and DANE prerequisites over DNS (TLSA at _25._tcp of the lowest-preference MX) with outage reported as unknown, never as absence. Returns grade (A-F) with grade_reasons, a verdict (valid/partial/invalid/not_configured), structured findings (TLS_RPT_NO_RECORD, TLS_RPT_INVALID_VERSION, TLS_RPT_MULTIPLE_RECORDS, TLS_RPT_NO_RUA, TLS_RPT_RUA_INVALID_URI, TLS_RPT_NO_VALID_RUA, TLS_RPT_NO_ENFORCEMENT_POLICY), and an `analysis` block with parsed tags, per-URI rua validation detail, and the prerequisite probe results.

_ try it 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.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. 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.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 0de47280d8de714e.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/0de47280d8de714e/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.

_ how we know
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
0

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

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
