Open weekly security base rates (CC BY 4.0), plus live DMARC, takeover and WHOIS checks.
Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →
Endpoint Security46
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 6 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability81
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 657 tokens (~109/item across 6 items; 6 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management10
- Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 20 Aug 26 0
- Server version: 1.4.9 → 1.4.10 functional
- 19 Aug 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.
- 18 Aug 26 0
- Stability: unverified → 0.03 ▲ functional

First indexed and scored.
Diagnostic detail from the automated scan of this channel: what the scanner observed at each step, so you can see exactly where a check passed or failed. It is informational only and never changes the trust score.

check_email_auth Check email authentication (live) ~90
Live SPF, DKIM and DMARC audit of up to 50 domains the user owns or asks about. Returns a per-domain breakdown plus a portfolio grade. Compare against the base rates: most of the web fails these controls. Rate-limited per client.
| Name | Type | Req | Description |
|---|---|---|---|
| domains | – | yes | Domains to audit (1-50). Array preferred; a JSON-encoded array or comma/space-separated string also works. |
No output schema declared.
No examples provided.
check_subdomain_takeover Check subdomain takeover exposure (live) ~68
Live scan of one domain: enumerate its subdomains (CT logs + DNS), then test each for dangling references on 13 cloud providers. Slow on large domains (up to a few minutes). Rate-limited per client.

check_whois Check domain registrations (live) ~73
Live WHOIS lookup for up to 100 domains: expiry date, registrar, nameservers. Use to catch registrations about to lapse. Rate-limited per client.
| Name | Type | Req | Description |
|---|---|---|---|
| domains | – | yes | Domains to look up (1-100). Array preferred; a JSON-encoded array or comma/space-separated string also works. |

No examples provided.
find_base_rate Find a base rate by keyword ~64
Search the Quiet Failures base rates by keyword (e.g. "dmarc", "certificate expiry uk", "subdomain takeover"). Returns matching metrics and their most citable segments.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | Keywords to search for (at least 2 characters) |

get_base_rate Get one base rate in full ~122
Full detail for one Quiet Failures base rate segment: the figure with confidence interval, how it is measured, why it matters, the limits of the measurement, the recent time series, and the canonical source URL to cite. Segment defaults to "global"; country slugs (gb, fr, us…) and company cuts (gb-companies, gb-small…) are also published.
| Name | Type | Req | Description |
|---|---|---|---|
| metric | string | yes | Metric id, e.g. "dmarc-policy" (see list_base_rates) |
| segment | string | – | Segment slug, default "global" |
No output schema declared.
No examples provided.
list_base_rates List security base rates ~62
Catalog of all published Quiet Failures base rates: metric id, the global question, the current global figure, sample size, severity, and every published segment slug (valid `segment` values for get_base_rate). Use get_base_rate for full detail on one.
