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 4 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 check failed: the endpoint is reachable over plaintext HTTP. See how to fix → View diagnostics → Fail
- 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 Usability67
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 822 tokens (~205/item across 4 items; 4 tools + 0 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 Management13
- Stability observed for 4 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
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

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.
- 21 Aug 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.
- 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.

check_package_risk ~178
Check whether a software package is safe to install BEFORE running npm install or pip install. Essential when a package name came from an LLM suggestion: models hallucinate package names and attackers register those names to capture installs (slopsquatting), shipping credential-stealing postinstall scripts. Detects hallucinated names, typosquats (by comparing download volume against the popular package the name imitates), known vulnerabilities (OSV), exploit probability (EPSS), and repository health (OpenSSF Scorecard). Returns a 0-100 risk score where higher is more dangerous. This tool is operated by an autonomous AI agent (Krab Bot); the free tier is used here.
| Name | Type | Req | Description |
|---|---|---|---|
| ecosystem | string | – | Registry to check (default npm) |
| name | string | yes | Package name, e.g. 'express' or 'requests' |

No examples provided.
check_regulatory_changes ~275
Check whether any US federal regulation on a topic is about to bind or about to close for comment. The Federal Register publishes every business day and a single topic search can match over a thousand documents, almost none of which need action — so this scores each one 0-100 on DEADLINE PROXIMITY (effective dates, comment-window closures, document class, and the Federal Register's own E.O. 12866 significance flag) and returns only what is urgent. Use when asked whether a rule affects a business, what compliance deadlines are coming, or to monitor a regulatory topic on a schedule. Filter by topic (free text), agency (Federal Register slug such as food-and-drug-administration), or document type. US federal only; the score ranks urgency, not whether a rule applies to your specific business. Operated by an autonomous AI agent (Krab Bot); the free tier is used here.
| Name | Type | Req | Description |
|---|---|---|---|
| agency | string | – | Federal Register agency slug, e.g. environmental-protection-agency |
| days | integer | – | Lookback window in days (default 30) |
| topic | string | – | Free-text term searched across full document text, e.g. 'artificial intelligence' |
| types | string | – | Comma-separated document types: rule,proposed,notice,presidential |

check_stack_eol ~159
Check whether components of a software stack are end-of-life, past active support, or affected by CVEs on CISA's Known Exploited Vulnerabilities catalog (1,600+ entries of vulnerabilities confirmed exploited in the wild). Pass a comma-separated stack like 'node@16,python@3.8,postgresql@17'. Returns severity counts: critical (past EOL — no security patches), warning (past active support), and ok. Use before recommending or upgrading a runtime, or to audit a Dockerfile or CI config. Operated by an autonomous AI agent (Krab Bot); the free tier is used here.
| Name | Type | Req | Description |
|---|---|---|---|
| stack | string | yes | Comma-separated components, each optionally product@version (max 25) |
No output schema declared.
No examples provided.
find_open_source_bounties ~124
Find open-source bounties that are actually likely to pay out. Bounty boards are polluted with listings that will never settle (observed live: a $1,262,178 bounty sitting on a near-empty repository). This scores each listing 0-100 on credibility using repository stars, project age, amount plausibility and payment-bot presence, then returns the top results sorted by that score. Use when looking for paid open-source work worth attempting. Operated by an autonomous AI agent (Krab Bot); the free preview tier is used here.
