Gov Mcp Servers

Cybersecurity Vulnerability Intelligence MCP Server

Unified vulnerability intelligence from 4 government data sources in a single MCP server. Get enriched CVE lookups with CVSS scores, active exploitation status, exploitation probability, and ATT&CK techniques in one call.

| Source | What It Provides | Update Frequency | |--------|-----------------|-----------------| | NIST NVD 2.0 | CVE details, CVSS scores, descriptions, references, CWE classifications | Continuous | | CISA KEV | Actively exploited vulnerabilities catalog, remediation deadlines | Daily | | FIRST.org EPSS | Exploitation probability scores (0-1) predicting likelihood of exploitation in next 30 days | Daily | | MITRE ATT&CK | Adversary techniques mapped to CVEs | Quarterly |

Tools

vuln_lookup_cve — Enriched CVE Lookup

The killer feature. Look up any CVE and get intelligence from all 4 sources in a single call.

• Input: { cveId: "CVE-2021-44228" }
• Returns: NVD details + CVSS score + KEV exploitation status + EPSS probability + ATT&CK techniques

vuln_search — Search CVEs

Search the NVD by keyword, severity, and date range. Optionally filter to only actively exploited (KEV) vulnerabilities.

• Input: { keyword: "apache log4j", severity: "CRITICAL", hasKev: true, limit: 20 }

vuln_kev_latest — Recently Exploited Vulnerabilities

Get vulnerabilities recently added to CISA's Known Exploited Vulnerabilities catalog.

• Input: { days: 7, limit: 20 }

vuln_kev_due_soon — Upcoming Remediation Deadlines

Get KEV entries with remediation deadlines approaching. Critical for federal compliance.

• Input: { days: 14, limit: 20 }

vuln_epss_top — Highest Exploitation Probability

Get CVEs most likely to be exploited in the next 30 days based on EPSS machine learning model.

• Input: { threshold: 0.7, limit: 20 }

vuln_trending — Newly Published Critical CVEs

Get recently published high/critical severity CVEs from the NVD.

• Input: { days: 3, severity: "CRITICAL", limit: 20 }

vuln_by_vendor — Vendor Vulnerability Assessment

Search CVEs for a specific vendor/product. Cross-references with CISA KEV to flag actively exploited issues.

• Input: { vendor: "microsoft", product: "windows", limit: 20 }

Use Cases

• Vulnerability triage: Look up a CVE and instantly know if it's actively exploited, its EPSS score, and what ATT&CK techniques apply
• Patch prioritization: Combine KEV status + EPSS scores to prioritize remediation
• Compliance tracking: Monitor upcoming CISA KEV remediation deadlines
• Threat intelligence: Track trending CVEs and newly weaponized vulnerabilities
• Vendor risk assessment: Assess a vendor's vulnerability exposure and active exploitation status
