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 Security57
- 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 1 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 is enforced; there's no plaintext access path. View diagnostics → Pass
- 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 Usability69
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 281 tokens (~281/item across 1 items; 1 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 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.
- 6 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.
- 5 Aug 26 +24
- Authorization: Authorisation not fully verified: no authorisation is required to call this server, and 1 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. security

verify_package Verify Package ~281
Dependency Trust Oracle. Call this BEFORE writing any package into a manifest (package.json, requirements.txt, pyproject.toml, ...). It checks whether the package actually exists on its registry, cross-references OSV.dev for known CVEs, pulls the package's OpenSSF Scorecard via deps.dev, and runs a Levenshtein-distance typosquat/slopsquat check against a curated list of popular packages combined with the package's publish age. Returns a synthetic verdict: ALLOW (no issues found), WARN (proceed with caution — read the findings before installing), or BLOCK (do not install — likely a hallucinated package name, an active typosquat, or a known critical/high-severity vulnerability). Always call this before running an install command for a package you have not already verified in this session. First 5 calls per caller are free; after that this tool requires x402 payment (USDC on Base) and will return a payment-required error with the amount and address to pay.
| Name | Type | Req | Description |
|---|---|---|---|
| ecosystem | string | yes | Package registry to check the name against. |
| name | string | yes | Exact package name as it would appear in the manifest (case-sensitive for npm scoped packages). |
| version | string | – | Optional exact version string to verify (e.g. "4.17.21"). Omit to check only the package name. |
