Overview

Description from the maker (original English)

Query CISA KEV / EPSS vulnerability feeds with full per-record provenance and auditable versions

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Cybersecurity
  • You need to fill in: PURIFY_API_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: PURIFY_API_KEY, PURIFY_API_URL

Values marked secret are keys to your account. Never share them or paste them into a chat.

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "purify-feeds": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e",
        "PURIFY_API_KEY",
        "-e",
        "PURIFY_API_URL",
        "ghcr.io/eason4kim-rocket/purify-feeds-mcp:1.0.1"
      ],
      "env": {
        "PURIFY_API_KEY": "your-value",
        "PURIFY_API_URL": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add purify-feeds --env PURIFY_API_KEY=your-value --env PURIFY_API_URL=your-value -- docker run -i --rm -e PURIFY_API_KEY -e PURIFY_API_URL ghcr.io/eason4kim-rocket/purify-feeds-mcp:1.0.1

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "purify-feeds": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e",
        "PURIFY_API_KEY",
        "-e",
        "PURIFY_API_URL",
        "ghcr.io/eason4kim-rocket/purify-feeds-mcp:1.0.1"
      ],
      "env": {
        "PURIFY_API_KEY": "your-value",
        "PURIFY_API_URL": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "purify-feeds": {
      "type": "stdio",
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e",
        "PURIFY_API_KEY",
        "-e",
        "PURIFY_API_URL",
        "ghcr.io/eason4kim-rocket/purify-feeds-mcp:1.0.1"
      ],
      "env": {
        "PURIFY_API_KEY": "your-value",
        "PURIFY_API_URL": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • PURIFY_API_KEY secret required env
    API key for the public feeds gateway (issued manually during the pilot — open a GitHub issue to request one)
  • PURIFY_API_URL env
    Feeds API base URL (defaults to the public gateway https://feeds.verifly.pro/feeds-api)

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Purify Security Feeds safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: PURIFY_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Docker on your computer.

What can I use instead?

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

ToolPurpose
list_feedsList feeds with record counts and current version (dataset artifact hash)
search_feedAND filters / sort / up to 50 rows, plus an exact total_matched count
get_provenanceReturn a record's _purify passport and the feed's run chain, by CVE id
check_feed_changedIncremental primitive: compare a known hash to detect new feed versions

Feeds

NameContents
kevCISA Known Exploited Vulnerabilities catalog
epssEPSS high-risk slice (exploit prediction scores)
enrichedEPSS + KEV joined view with risk bands

Install

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

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

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

Or build from source:

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:

{

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

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

{

"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": " " } } } }

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.
