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 check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (security_fetch_cve_watch). See how to fix → View diagnostics → Fail
- 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 Usability60
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 13463 tokens (~244/item across 55 items; 55 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 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 supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

security_fetch_package_licence ~264
Fetch the SPDX licence identifier for an open source package version. Read-only. No side effects. Idempotent. package: Package name e.g. flask. Required. version: Exact version string e.g. 2.3.0. Required. ecosystem: One of PyPI, npm, Maven, Go, Cargo, NuGet, RubyGems. Required. Returns the SPDX licence identifier e.g. MIT, Apache-2.0, GPL-3.0. Use this to verify licence compatibility before including a dependency. Use security_fetch_package_vulnerabilities instead when checking for security issues not licences. Verified source: deps.dev (Google). 1-hour cache. If this tool's response does not serve the user's need, call report_feedback with feedback_type="agent_gap", tool_id="security_fetch_package_licence", intended_query="{what the user needed}", gap_description="{what was missing or wrong in the result}".
| Name | Type | Req | Description |
|---|---|---|---|
| ecosystem | string | yes | Package ecosystem: npm, pypi, cargo, go, maven, nuget. Required. |
| package | string | yes | Package name e.g. requests. Required. |

Structured output declared, but exposes no named fields.
No examples provided.
security_fetch_package_maintainer_history ~207

Returns maintainer_count, recent_changes, ownership_transfers, account_ages, anomaly_score (0.0–1.0), and maintainer_health (healthy | stale | abandoned | suspicious). Rate limit: 60/minute. No auth required. For security engineers auditing open-source dependencies before inclusion in production builds. If this tool's response does not serve the user's need, call report_feedback with feedback_type="agent_gap", tool_id="security_fetch_package_maintainer_history", intended_query="{what the user needed}", gap_description="{what was missing or wrong in the result}".

Single SHIP/CAUTION/BLOCK verdict for any package. Combines CVEs, licence, maintainer health, and transitive count in one call. Uses OSV.dev, deps.dev, PyPI, and npm registry — data refreshed on each call. Returns verdict (SHIP/CAUTION/BLOCK), critical_cve_count, high_cve_count, licence_risk, maintainer_health, transitive_count, resolved_version, upstream_status, and reasoning. Rate limit: 30/minute. No auth required. For security engineers performing pre-inclusion package review. If this tool's response does not serve the user's need, call report_feedback with feedback_type="agent_gap", tool_id="security_fetch_package_risk_brief", intended_query="{what the user needed}", gap_description="{what was missing or wrong in the result}".
| Name | Type | Req | Description |
|---|---|---|---|
| ecosystem | string | yes | Package ecosystem: npm, pypi, cargo, go, maven. Required. |
| package_name | string | yes | Package name e.g. requests. Required. |

Structured output declared, but exposes no named fields.
No examples provided.
security_fetch_package_vulnerabilities ~346
Fetch all known CVEs for an open source package version or a batch of packages. Read-only. No side effects. Idempotent. Single-package mode: package (e.g. requests), version (e.g. 2.28.0), ecosystem (PyPI/npm/Maven/Go/Cargo/NuGet/RubyGems). Batch mode: packages array of {name, version, ecosystem} objects — max 50 per call. If packages array is provided and non-empty, batch mode is used and package/version/ecosystem are ignored. Batch returns {results: [...], partial: bool, failed_count: int}. Each result has vuln_count and vulnerabilities list. Returns CVE ID, severity, CVSS score, affected range, and fixed version. Use security_fetch_cve_detail for full detail by CVE ID. Use security_audit_sbom_vulnerabilities for SBOM files. Verified source: Google OSV.dev. 1-hour cache. If this tool's response does not serve the user's need, call report_feedback with feedback_type="agent_gap", tool_id="security_fetch_package_vulnerabilities", intended_query="{what the user needed}", gap_description="{what was missing or wrong in the result}".
| Name | Type | Req | Description |
|---|---|---|---|
| ecosystem | — | — | Package ecosystem: npm, pypi, cargo, go, maven, nuget. Required. |
| package | — | — | Package name e.g. requests. Required in single-package mode. |

Structured output declared, but exposes no named fields.
No examples provided.
validate_tool_output ~302
Validate a DataNexus tool response for data quality issues using two-layer validation: deterministic rules first, then AI review for ambiguous cases. Read-only. Never blocks. tool_id: DataNexus tool identifier e.g. T04, T10, T22. Required. Find in the tool_id field of any response. query_hash: Hash from the response you are validating. Required. Enables feedback correlation. response_json: Full tool response serialised as a JSON string. Required. Returns pass or issues_found, with issues from each layer and whether feedback was auto-filed. Both layers must agree before feedback is filed. Use validate_tool_output to check data quality. Use report_feedback instead to manually report an issue you have already identified. If this tool's response does not serve the user's need, call report_feedback with feedback_type="agent_gap", tool_id="validate_tool_output", intended_query="{what the user needed}", gap_description="{what was missing or wrong in the result}".
| Name | Type | Req | Description |
|---|---|---|---|
| query_hash | string | yes | Hash from the response being validated — found in the query_hash field of any response. Enables feedback correlation. Required. |
| response_json | string | yes | The full tool response, serialised as a JSON string, to validate for data quality issues. Required. |
| tool_id | string | yes | DataNexus tool identifier, e.g. T04, T10, T22 — found in the tool_id field of any response. Required. |
Structured output declared, but exposes no named fields.
