Category Security
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security81
- No malware found by supply-chain analysis.Pass
- CVE check failed: a known high-severity CVE affects zod 3.25.76, a direct dependency. A fixed version is available. View diagnostics → Fail

- 30 of 98 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass

- Actively maintained (last published 212 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability87
- 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
- Tool/resource definitions use about 499 tokens (~83/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 Management100
- No destabilizing schema changes in the last 30 days.Pass
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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
accept_risk Accept Risk ~171
Record an accepted risk for a CVE, with a reason and mandatory expiry date. Expiry beyond 1 year requires confirm_extended_expiry=true.
| Name | Type | Req | Description |
|---|---|---|---|
| confirm_extended_expiry | boolean | – | Set to true to confirm an expiry date more than 1 year away |
| cve_id | string | yes | The CVE ID to accept, e.g. CVE-2021-44228 |
| cvss_score | number | – | CVSS score of the CVE at the time of acceptance (snapshot) |
| expires_on | string | yes | Expiry date in YYYY-MM-DD format. Required. |
| reason | string | yes | Business justification for accepting this risk |
| severity | string | yes | Severity label of the CVE at the time of acceptance (snapshot). Use UNKNOWN if severity is unavailable. |
No output schema declared.
No examples provided.

Check a list of packages against OSV.dev for known vulnerabilities. Returns CVEs above the severity threshold as a numbered list, suppressed/accepted risks, expired acceptances, and a count of below-threshold findings.
| Name | Type | Req | Description |
|---|---|---|---|
| min_severity | string | – | Minimum severity to surface in detail: CRITICAL, HIGH, MEDIUM, or LOW. If omitted, GhostFree will determine the threshold automatically. |
