This server serves four CISA datasets, all keyless and all read-only. Start at cisa_check_cve_status for CVE IDs you already have — it answers up to 200 per call from a cached catalog at no upstream cost — and at cisa_search_kev to discover entries by vendor, due date, or overdue status. cisa_get_ssvc adds the SSVC decision points CISA publishes per CVE and computes the BOD 26-04 remediation timeline they imply for an asset exposure you supply; that computation is CISA's published decision logic applied to CISA's published inputs, not a compliance determination. ICS advisories are served from…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

cisa_list_reference unknown never probed
Decode the vocabulary the other CISA tools take as input. Topics cover the BOD 26-04 remediation timeline table and what each tier means, the KEV record fields and their value domains, the SSVC decision points CISA publishes, the critical-infrastructure sector names as the advisory corpus spells them, advisory ID formats, CVSS severity bands, and the freshness of the data this server currently holds. Call this before constructing filters for cisa_search_kev or cisa_search_ics_advisories, and whenever another tool's recovery hint points here.

cisa_check_cve_status unknown never probed
Check CVE IDs against the CISA Known Exploited Vulnerabilities catalog — up to 200 per call, served from a cached catalog snapshot at no upstream cost. Returns, per CVE, whether it is in KEV and if so the date added, the federal remediation due date, days remaining or days overdue, which binding operational directive the entry cites, the required action text, whether it is linked to ransomware campaigns, whether it falls in the three-day forensic-triage tier, CISA's own vendor and product labels, associated CWEs, and the reference URLs parsed from the entry's notes. A CVE that is not in KEV is a normal result, not an error. The CWE IDs returned chain directly into cisa_search_kev's CWE filter, and the parsed NVD reference gives the canonical record for scoring detail.

cisa_search_kev unknown never probed

Search the CISA Known Exploited Vulnerabilities catalog across every entry in the cached snapshot. Filter by vendor or product using CISA's own labels, by name substring, by CWE, by the date an entry was added, by due date, by overdue status, by ransomware linkage, by the three-day forensic-triage tier, or by which binding operational directive the entry cites. Results are paged and sortable by due date or date added. Vendor and product values are CISA's free-text labels, not CPE names — call cisa_list_reference for the field vocabulary before guessing one. The catalog records additions but carries no per-record modified timestamp, so dateAddedFrom answers "what is new since D" while a revised due date on an existing entry is not detectable from the feed.

cisa_get_ssvc unknown never probed

Fetch the SSVC decision points CISA publishes per CVE as a CVE Authorized Data Publisher — Exploitation, Automatable, and Technical Impact — along with the CVSS score and CWE CISA contributes where present, and compute the BOD 26-04 remediation timeline those values imply for the asset exposure you supply. The computed timeline applies CISA's published decision table to CISA's published decision points and your stated exposure; it is not a compliance determination and it is not CISA's own due-date assignment, which is reported separately when the CVE is in KEV and can differ. Not every CVE is enriched — a miss returns found false with guidance rather than an error. Call cisa_list_reference with topic ssvc_values for the decision-point vocabulary.

cisa_search_ics_advisories unknown never probed

Search the CISA industrial control system advisory corpus — 3,926 CSAF 2.0 documents covering PLC, HMI, SCADA, building-automation, and medical-device products from 2010 onward. Filter by vendor, product, CVE, CVSS range, severity band, critical-infrastructure sector, advisory series, publication date, or revision date, and run full-text search over advisory titles and product names. Sector filtering reaches only advisories that carry a sector note, which begins in 2017; the response reports how many documents a sector filter can never match. Returns advisory IDs for cisa_get_advisory, the CVEs each advisory covers, and the source URL and attribution every advisory response carries.

Read one CISA industrial control system advisory in full: affected products flattened from the CSAF product tree into vendor, product, and version ranges; per-CVE CVSS score, vector, and CWE; remediations with their category and vendor instructions; critical-infrastructure sectors; and the revision history. Large advisories return a section outline instead of the whole document — re-call with the sections you need. Republished vendor advisories carry the originating vendor's text; every response reports the source URL and attribution. Find advisory IDs with cisa_search_ics_advisories.

List what CISA has published recently — its combined advisory feed, its alerts feed, or its ICS advisory feed. Each feed is a rolling window of exactly 30 items with no history, no pagination, and no date-range query, so the window's coverage varies from about a week to about two months depending on the feed. For ICS advisory history beyond the window, use cisa_search_ics_advisories, which covers the full corpus back to 2010.

_ 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.

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

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