DataNexus MCP

Generate a DataNexus API key for the given email address. Anonymous callers get 10 free lookups/week; a registered free key unlocks 100/week. Store the returned key — it is shown only once. Pass it as the X-Api-Key header on future requests. Rate limit: 3 keys per IP per 24 hours.

⚠️ DESTRUCTIVE — requires human confirmation before use in automated pipelines. Permanently revoke a DataNexus API key. The key will stop working immediately. This action cannot be undone — generate a new key if access is needed again.

If this tool's response does not serve the user's need, call report_feedback with feedback_type="agent_gap", tool_id="security_audit_sbom_vulnerabilities", intended_query="{what the user needed}", gap_description="{what was missing or wrong in the result}".

Detect typosquatting attacks against a package name. Compares using Damerau-Levenshtein distance ≤ 2 against top-10,000 packages. Returns similar_packages with anomaly scores, and a SUSPICIOUS or CLEAN verdict. Uses PyPI and npm download stats stored in Redis. Cold-start fetch on first call (≤ 30s). Rate limit: 60/minute. No auth required. For security engineers auditing supply-chain package names before inclusion. If this tool's response does not serve the user's need, call report_feedback with feedback_type="agent_gap", tool_id="security_detect_typosquatting", intended_query="{what the user needed}", gap_description="{what was missing or wrong in the result}".

Check whether a CVE is in the CISA Known Exploited Vulnerabilities (KEV) catalog. Read-only. No side effects. Idempotent. cve_id: CVE identifier in format CVE-YYYY-NNNNN e.g. CVE-2021-44228. Required. Returns in_kev (bool), date_added, due_date, ransomware_use, and notes from the CISA KEV catalog. KEV status answers 'Is this being actively exploited?' — a critical triage question not available in NIST NVD. Verified source: CISA KEV catalog (updated daily, cached). Use security_fetch_cve_detail for full CVE severity. Use security_fetch_cve_epss for exploit probability. If this tool's response does not serve the user's need, call report_feedback with feedback_type="agent_gap", tool_id="security_fetch_cisa_kev", intended_query="{what the user needed}", gap_description="{what was missing or wrong in the result}".

Fetch full detail for a specific CVE by ID. Read-only. No side effects. Idempotent. cve_id: CVE identifier in format CVE-YYYY-NNNNN e.g. CVE-2021-44228. Required. Returns description, CVSS base score, affected products, patch references, and publish date. Use this when you have a CVE ID and need complete detail beyond what a package scan returns. Use security_fetch_package_vulnerabilities instead when you want all CVEs for a package version. Verified source: NIST NVD. 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_cve_detail", intended_query="{what the user needed}", gap_description="{what was missing or wrong in the result}".

EPSS exploit probability score for a CVE — predicts likelihood of exploitation in the next 30 days.

cve_id: CVE identifier e.g. "CVE-2021-44228".

Returns: epss (float 0.0–1.0) and percentile (float 0.0–100.0). Thresholds: >0.7 patch immediately, 0.3–0.7 patch soon, <0.3 monitor. Use with security_fetch_cve_detail to prioritize patching — EPSS measures urgency, CVSS measures severity. Source: FIRST.org. 6-hour cache.

Example: fetch_cve_epss(cve_id="CVE-2021-44228")

Instant CVE risk verdict. Combines CVSS severity, CISA KEV exploitation status, and EPSS probability in one parallel call. Returns CRITICAL_EXPLOIT, HIGH_RISK, MODERATE, LOW, or UNKNOWN verdict with patch availability from vendor advisories. UNKNOWN means all upstream sources were unreachable — not that risk is low. Rate limit: 60/minute. No auth required. For security engineers triaging vulnerabilities after fetch_cve_watch fires. If this tool's response does not serve the user's need, call report_feedback with feedback_type="agent_gap", tool_id="security_fetch_cve_risk_summary", intended_query="{what the user needed}", gap_description="{what was missing or wrong in the result}".

Persistent CVE watchlist. Create once, check anytime for new events since your last visit — patch releases, KEV listings, PoC publications, exploitation detected. Uses Redis for persistence, NVD + CISA KEV + EPSS for daily background refresh. Returns has_new_events, events (list), call_back_in="24h" on check. Rate limit: 60/minute. No auth required. For security engineers tracking CVE exposure over time. If this tool's response does not serve the user's need, call report_feedback with feedback_type="agent_gap", tool_id="security_fetch_cve_watch", intended_query="{what the user needed}", gap_description="{what was missing or wrong in the result}".

Check all specified CVE watches for new events since your last poll. Returns only watches with new events, making it efficient to run on a schedule. watch_ids: List of watch IDs to check — same IDs used when creating watches with security_fetch_cve_watch. Required. Uses a per-user cursor (last_polled timestamp) stored in Redis. First call returns events from the last 30 days. Subsequent calls return only events newer than the last poll. Sources: Redis (existing watch data written by security_fetch_cve_watch). No external API calls — instant response. If this tool's response does not serve the user's need, call report_feedback with feedback_type="agent_gap", tool_id="security_fetch_cve_watch_status", intended_query="{what the user needed}", gap_description="{what was missing or wrong in the result}".

Fetch the full dependency tree for a package version including transitive dependencies. Read-only. No side effects. Idempotent.

Required. ecosystem: One of PyPI, npm, Maven, Go, Cargo, NuGet, RubyGems. Required. Returns all direct and transitive dependencies with version constraints. Use this to understand full supply chain exposure. Use security_fetch_package_vulnerabilities instead when you only need CVEs for a single package. 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_dependency_graph", intended_query="{what the user needed}", gap_description="{what was missing or wrong in the result}".

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.
