Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 63 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-06-18, serverInfo.name seclens.

  • Pass
    Lists tools

    tools/list returned 3 tools.

  • Pass
    Current protocol

    Negotiated 2025-06-18. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 63 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 63 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    4 of 4 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-10-27T14:48:50.789887Z, within 180 days.

Capabilities

Tools 3

assess_domain

Start a fresh public email-security check of one domain (SPF, DKIM, DMARC, MTA-STS, TLS-RPT, DANE, DNSSEC, MX and BIMI). Use this when there is no stored result yet or you need an up-to-date one; to read an existing result, call get_result instead. It returns only a queue confirmation, not the report. The response includes poll_after_ms. Wait that long, then poll get_result. A check usually takes a few seconds and is stopped after 45 seconds at most.

Discovered
get_result

Return the latest stored public report for one domain: score from 0 to 100, profile (mail, null_mx or no_mx), per-protocol findings, and Remediation.packs with the DNS records to publish. BIMI is reported but does not change the score. Use this to read a report or to poll after assess_domain; use get_summary for figures across all domains instead. If the domain has not been checked yet, or the check is still running, it returns HTTP 404 JSON with error not_found. In that case call assess_domain and poll again. Public reports expire after 24 hours.

Discovered
get_summary

Return totals for every domain in the public SecLens.ONE corpus, plus a list of those domains with their latest score, newest first. "stats" holds the domain count, average score, score bands and per-protocol present and effective counts. "results" holds one row per domain (Domain, Score, Generated, Profile, IsMailEnabled, HasNullMX, NullMXCompliant). Use this for overall adoption figures, not for one domain's details (use get_result instead). By default, results lists the 50 newest domains and is about 8 KB. The maximum limit is 500. Stats always cover the full corpus. Set stats_only to true for stats and an empty results list.
