Ship Trustworthy Security Answers, FastVulners MCP gives your agents the full vulnerability picture on demand - without teaching them the Vulners API or juggling parameters. The agent sends a CVE ID or a product + version, and MCP returns a compact fact set plus a map of related document IDs from the Vulners database. Your model then expands only what it needs - advisories, patches, PoCs, KEV entries, NVD records, vendor notes—keeping prompts lean and answers verifiable.
Why the Document Map Matters (and Kills Hallucinations)LLMs will answer even when they shouldn’t. MCP forces a better pattern: ID → facts → evidence map → citations.- Answers anchored to sources: Each claim can point to a concrete document ID (vendor advisory, KEV item, PoC repo, distro notice). If there’s no doc, the agent has nothing to cite - nudging it to say “no evidence” instead of inventing details.
- Selective expansion: The model expands only the documents it needs from the map, which means fewer stray web searches and fewer made-up references.
- Consistent provenance: Every document handle is stable and typed (e.g., vendor advisory vs. exploit reference), so your prompts can require evidence per claim class.
- Conflict-aware reasoning: When sources disagree (e.g., vendor vs. NVD), the agent can fetch both IDs and present a reconciled view with citations - no guesswork.
- Token discipline: Facts first, docs on demand. You minimize prompt bloat while maximizing reliability and traceability.
Fast Time-to-Context & Minimal WiringPlug MCP into your agent once. From then on, the flow is simple:- Ask: “CVE-2025-XXXX” or “vendor product 3.2.1”.
- Get: normalized facts (CVSS vectors, EPSS, KEV, exploit presence) and a graph of related document IDs to pull on demand.
- No bespoke ETL, no schema guessing - just ID-in → context & document handles-out, ready for citations and follow-ups.
Built for Product & Corporate Teams- Product teams: In-app copilots, PR annotators, and customer-facing chat that cite vendor advisories and PoCs with links users trust—without bloating prompts.
- Corporate teams: Incident triage, ticket routing, and asset impact checks that retrieve the exact docs (Patch Tuesday notes, distro advisories, KEV items) relevant to your environment.
