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 Security83
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability74
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 17077 tokens (~294/item across 58 items; 55 tools + 3 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 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
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

threat_intel Threat Intel ~115
Check domain against abuse.ch URLhaus for known malware-distribution URLs (single source — for multi-feed correlation use ioc_lookup which adds ThreatFox and, for IPs, Feodo Tracker). Use for fast domain-level threat assessment; use phishing_check for specific URLs. Free: 30/hr, Pro: 500/hr. Returns {malware_urls, threat_tags, threat_status, summary}.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | yes | Domain to check for threats (e.g. 'suspicious-site.com', 'example.com') |
| Name | Type | Req | Description |
|---|---|---|---|
| result | — | yes | — |
No examples provided.
threat_report Threat Report ~223
Query comprehensive threat profile for an IP: Shodan host data, AbuseIPDB reputation, ASN/geolocation, and open ports. Use for IP investigation and SOC alert triage; for domain data use domain_report. Note: nested asn block always returns at most 50 IPv4/IPv6 prefixes — call asn_lookup with include_full_prefixes=True for the full announced-prefixes list. enrichment.vulns is severity-aware list[VulnInfo] (cve_id + severity + cvss_v3) — Phase 2 v1.16.0 BREAKING; pre-1.16 it was list[str] of CVE IDs. Free: 30/hr (costs 6 tokens), Pro: 500/hr. Returns {ip, enrichment, abuseipdb, shodan, asn, threat_level}.
| Name | Type | Req | Description |
|---|---|---|---|
| ip | string | yes | Public IPv4 or IPv6 address to investigate (e.g. '8.8.8.8', '1.1.1.1'). Private/reserved IPs are rejected. |
| Name | Type | Req | Description |
|---|---|---|---|
| result | — | yes | — |
No examples provided.
username_lookup Username Lookup ~127
Search for username across 15+ social/dev platforms (GitHub, Reddit, X/Twitter, LinkedIn, Instagram, TikTok, Discord, YouTube, Keybase, HackerOne, etc.). Use for OSINT investigations and identity verification. Free: 30/hr, Pro: 500/hr. Returns {username, total_found, platforms: [{name, exists, url, status_code}]}.
| Name | Type | Req | Description |
|---|---|---|---|
| username | string | yes | Username string to search across platforms, without @ prefix (e.g. 'torvalds', 'johndoe', 'elonmusk') |
| Name | Type | Req | Description |

No examples provided.
wayback_lookup Wayback Lookup ~241
Retrieve Wayback Machine snapshots for a domain: first capture, latest, total count, snapshot list. Use to investigate domain history and age; for full audit use domain_report. Free: 30/hr, Pro: 500/hr. status='ok' means the count is authoritative (even when 0 → confirmed no archives). status='unavailable' means CDX timed out/rate-limited/5xx — total_snapshots is OMITTED (unknown, NOT zero) and the agent should NOT report "no snapshots"; the warnings[] array carries the cdx_* error code (cdx_timeout/cdx_rate_limited/cdx_unavailable/cdx_error/cdx_parse_error/cdx_body_too_large). Heavy domains (kernel.org, microsoft.com, archive.org itself) frequently time out the CDX endpoint despite having millions of snapshots — fall back to archive_url for manual inspection. Returns {domain, status, total_snapshots, first_seen, last_seen, years_online, snapshots, archive_url, summary, warnings}.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | yes | Domain to look up in web archives (e.g. 'example.com', 'archive.org') |
