_ is it live, free and safe measured by this hub
Is nist-nvd-mcp-server live?
Yes — it answered the hub's last check (checked 1h ago). It answered 99% of checks over the last 30 days.
Is nist-nvd-mcp-server free to use?
Yes — the hub reached it with no key and no payment.
What tools does nist-nvd-mcp-server have?
5 tools: nvd_audit_cpe, nvd_search_cpes, nvd_get_cve, nvd_get_cve_history, nvd_search_cves.
Is nist-nvd-mcp-server safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

  • nvd_search_cves reads open 23h ago

    Search CVEs by keyword, severity, CWE, date range, or CISA KEV status. The primary discovery tool for vulnerability surveillance and triage workflows. pubDays and lastModDays are convenience shorthands that expand to date pairs; values over 120 days are clamped to the NVD maximum and reported in the response enrichment. Returns brief summaries — call nvd_get_cve for full detail on specific IDs. At least one filter is recommended; omitting all filters returns CVEs in default NVD index order (oldest first by CVE ID).

  • nvd_audit_cpe reads unknown 23h ago

    Find all CVEs affecting a specific product and version using CPE (Common Platform Enumeration). Requires either an exact CPE name (cpeName) or a partial match string (virtualMatchString) with optional version range bounds. With cpeName, NVD scopes results to configurations where the product is directly vulnerable, not merely referenced as a dependency. Use nvd_search_cpes first to resolve the correct CPE string for a product. Returns full CVE records.

  • nvd_search_cpes reads unknown 23h ago

    Search the NVD CPE (Common Platform Enumeration) dictionary by product keyword or partial match string. Returns CPE names, human-readable titles, and deprecation status. Use before nvd_audit_cpe to resolve the correct CPE name for a product — CPE strings are precise identifiers (e.g., cpe:2.3:a:apache:http_server:2.4.51:*:*:*:*:*:*:*) and must match exactly to audit the right product.

  • nvd_get_cve reads unknown 13h ago

    Fetch one or more CVEs by ID from the NIST National Vulnerability Database. Returns CVSS scores across all available versions (v2.0, v3.0, v3.1, v4.0), CWE weakness classifications, affected CPE configurations, CISA KEV fields, and references. Up to 100 CVE IDs per call. For bulk lookups of more than 10 IDs, use brief: true — full records for 100 CVEs can exceed 1MB and exhaust context budgets.

  • nvd_get_cve_history reads unknown 13h ago

    Retrieve the change history for a single CVE — CVSS score revisions, reference additions, status transitions (e.g., "Received" → "Analyzed"), and CPE configuration updates. Use when tracking a CVE's escalation or investigating when a score changed. Events are returned newest-first by default; pass order="oldest" for the CVE's earliest events. For the current record, call nvd_get_cve instead. The NVD history endpoint is significantly slower than other NVD endpoints, especially without an API key — set NVD_API_KEY for reliable operation.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 78dbd3eb2497956b.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/78dbd3eb2497956b/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
90%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
