Query CISA KEV / EPSS vulnerability feeds with full per-record provenance and auditable versions
Query CISA KEV / EPSS vulnerability feeds with full per-record provenance and auditable versions. Exposed over MCP by the purify security feeds mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.
MCP server for Purify's production security-intelligence feeds. Lets Claude Desktop, Cursor and other MCP clients query live CISA KEV / EPSS / enriched vulnerability feeds — every answer carries an auditable feed version and full per-record provenance.
Everything the assistant can do here goes through one of these:
list_feeds — List feeds with record counts and current version (dataset artifact hash)search_feed — AND filters / sort / up to 50 rows, plus an exact total_matched countget_provenance — Return a record's _purify passport and the feed's run chain, by CVE idcheck_feed_changed — Incremental primitive: compare a known hash to detect new feed versionsSetup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
You will need 2 environment variables: PURIFY_API_URL, PURIFY_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Purify Security Feeds's toolset — list_feeds, search_feed, get_provenance and 1 more — is a fair guide to whether it matches your workflow. It is maintained by eason4kim-rocket; worth a glance at recent repository activity before you build anything load-bearing on it.
