Documentation Overview

purify-feeds-mcp

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.

The feeds behind this server are continuously scheduled, quality-gated and self-healing. Each record ships with a _purify data passport: where it was fetched from, when, with which extractor, and the hash of the raw artifact it came from.

Tools

Tool	Purpose
`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` count
`get_provenance`	Return a record's `_purify` passport and the feed's run chain, by CVE id
`check_feed_changed`	Incremental primitive: compare a known hash to detect new feed versions

Feeds

Name	Contents
`kev`	CISA Known Exploited Vulnerabilities catalog
`epss`	EPSS high-risk slice (exploit prediction scores)
`enriched`	EPSS + KEV joined view with risk bands

Install

bash

go install github.com/eason4kim-rocket/purify-feeds-mcp@latest

Or use the Docker image (no Go toolchain needed):

Terminal

docker pull ghcr.io/eason4kim-rocket/purify-feeds-mcp:latest

Or build from source:

bash

git clone https://github.com/eason4kim-rocket/purify-feeds-mcp
cd purify-feeds-mcp && go build .

Configure (Claude Desktop)

~/Library/Application Support/Claude/claude_desktop_config.json:

config.json

{
  "mcpServers": {
    "purify-feeds": {
      "command": "/path/to/purify-feeds-mcp",
      "env": {
        "PURIFY_API_URL": "https://feeds.verifly.pro/feeds-api",
        "PURIFY_API_KEY": "<your-api-key>"
      }
    }
  }
}

Or with Docker (the image defaults PURIFY_API_URL to the public gateway):

config.json

{
  "mcpServers": {
    "purify-feeds": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "PURIFY_API_KEY",
               "ghcr.io/eason4kim-rocket/purify-feeds-mcp:latest"],
      "env": { "PURIFY_API_KEY": "<your-api-key>" }
    }
  }
}

The public gateway is read-only (GET only, feed whitelist, per-key rate limits). Health check: https://feeds.verifly.pro/healthz — no key needed. API keys are issued manually during the pilot — open an issue or contact the maintainer to get one.

Environment variables

PURIFY_API_URL — feeds API base URL (default http://127.0.0.1:8091 for local/dev use)
PURIFY_API_KEY — API key, sent as a bearer token (required for the public gateway)
PURIFY_FEEDS — override the built-in feed table: name=spec_id,...

Example prompts

"Which CVEs entered CISA KEV in the last 7 days? Give vendors and remediation due dates."
"How many CVEs have EPSS > 0.99 and are in KEV? Top 5?"
"Where does the data for CVE-2026-45659 come from?" (get_provenance returns the full passport)
Agent loops: remember artifact_hash, call check_feed_changed first on the next run, and only re-triage when the feed actually changed.
