Let AI install it

Copy this message into a Claude chat. The AI checks your computer, tells you which file it will change, and waits for your OK every time.

Please install the MCP server Vuln Check for Claude on this computer, in this order: 1) Check Node.js with node -v. If it is missing, tell me to install it from https://nodejs.org/en/download; do not install it yourself. 2) Use only this config (already checked by PopNx MCP): { "mcpServers": { "vuln-check": { "command": "npx", "args": [ "-y", "@ciloops/vuln-check", "mcp" ] } } } 3) Tell me the full path of the file you will change, or the command you will run, and wait for my OK. 4) No key is needed. 5) Do what we agreed, then check that the Vuln Check tools really show up.

This message has no key in it. If a key is needed, the AI will ask you to paste it yourself into the file or the app’s field.

Install Node.js (if you don’t have it)
Already installed? Check first · Open Terminal, type this command and press Enter
node -v
- A version number such as v26.13.1 = installed, skip this step
- "command not found" (on Windows: "is not recognized") = not installed yet, or installed but Terminal needs to be closed and reopened
How to open Terminal
Mac: press ⌘ + Space, type Terminal, press Enter
Windows: open Start, type Windows PowerShell, then Open
Not installed: Open the official download page, pick the LTS version and the click-through installer: .pkg on Mac · .msi on Windows. Double-click and follow it to the end. No curl command needed
Open the Node.js download page ↗
When it’s done, close Terminal, open it again and run the same command. You should see a version number: node -v

Common questions

Is Vuln Check safe?

It passed 3 of 3 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

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 24 days ago, and the latest version (0.1.3) reached the registry 24 days ago.

Which apps can use it?

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

What can I use instead?

vuln-check

Vulnerability truth for AI agents. Runs grype locally, merges an OSV freshness overlay, and returns a prioritised answer with concrete upgrade targets instead of a 40 KB JSON dump.

Any language with a lockfile (npm, PyPI, Go, Maven, Cargo, RubyGems, Composer, NuGet, Hex, Pub, Swift, R, Conan…), OS packages, container images, SBOMs.
One score per finding: CVSS + EPSS + CISA KEV + fix availability.
Remediation plan per package: smallest version that closes every finding, breaking flag.
CLEAN is ~20 tokens. Nothing runs on a server; nothing leaves your machine except the optional OSV query.

Install

# grype is required

brew install grype # or: curl -sSfL https://get.anchore.io/grype | sh -s -- -b /usr/local/bin

go install github.com/ciloops/vuln-check/cmd/vuln-check@latest

or

brew install ciloops/tap/vuln-check # macOS cask

or

npx @ciloops/vuln-check scan .

Binaries for Linux/macOS/Windows on the Releases page. Docker: ghcr.io/ciloops/vuln-check (bundles grype).

CLI

vuln-check scan .                               # agent format, OSV overlay on

vuln-check scan python:3.12-slim # image, pulled from the registry vuln-check scan sbom:bom.cdx.json vuln-check scan --format sarif --sarif-out out.sarif . vuln-check scan --fail-above 69 --no-osv . # CI gate, exit 2 above threshold vuln-check vuln CVE-2024-3094 vuln-check db update

Output (--format agent):

{"status":"ACTION_REQUIRED","target":"dir:.","packages":412,"findings":17,"shown":5,"sources":["grype","osv"],

"actions":[{"package":"pkg:npm/minimist","current":"1.2.5","target":"1.2.6","breaking":false,"fixes":["CVE-2021-44906"],"score":59}], "top":[{"id":"CVE-2021-44906","package":"minimist@1.2.5","severity":"CRITICAL","score":59,"epss":0.015,"fixed_in":["1.2.6"]}], "unfixable":3}

status: CLEAN | REVIEW (all findings < 40) | ACTION_REQUIRED. fresh: true marks advisories that came from OSV before grype-db ingested them. unfixable counts findings with no fix on the current release line.

Tools: scan_dir, scan_image, scan_sbom, vuln_lookup, db_update.

Claude Code:

claude mcp add vuln-check -- vuln-check mcp

or the plugin (adds a skill that tells Claude when to scan):

claude plugin marketplace add ciloops/vuln-check && claude plugin install vuln-check

Cursor / Windsurf / VS Code (.cursor/mcp.json, ~/.codeium/windsurf/mcp_config.json, .vscode/mcp.json):

{ "mcpServers": { "vuln-check": { "command": "vuln-check", "args": ["mcp"] } } }

Codex (~/.codex/config.toml):

[mcp_servers.vuln-check]

command = "vuln-check" args = ["mcp"]

Add --no-osv to the args to keep the dependency list off the network.

GitHub Action

- uses: ciloops/vuln-check@v1

with: target: . # or an image ref fail-above: 69 sarif: vuln.sarif

uses: github/codeql-action/upload-sarif@v3 if: always() with: { sarif_file: vuln.sarif }

Score

severity = CVSS base × 6 (label fallback) · exploit = EPSS × 30 · KEV: +10, floor 85 · no fix: × 0.85. Clamped to 0–100. See internal/score.

Freshness

grype-db builds daily and grype refreshes it at most every 2 h. The OSV overlay queries api.osv.dev with the purls grype inventoried (language ecosystems only) and adds anything grype-db has not seen yet, usually minutes after a GHSA is published. Disable with --no-osv.

Limits

No lockfile → transitive dependencies are invisible. Same as every scanner.
Remediation plans assume a linear release line per package; direct vs transitive is not distinguished yet.
Version comparison is a generic tokenizer, not per-ecosystem parsers. Good enough for "smallest fix above current"; edge cases exist (PEP 440 post-releases, exotic Maven qualifiers).

Development

go test ./...

go build ./cmd/vuln-check

Tests run against a fake grype (cmd/vuln-check/testdata/fake-grype.sh) and fixtures in internal/grype/testdata. CI runs a real grype e2e.

Release: tag vX.Y.Z → goreleaser publishes binaries, checksums, ghcr image, Homebrew cask for macOS (needs HOMEBREW_TAP_GITHUB_TOKEN and the ciloops/homebrew-tap repo) and the npm package via trusted publishing (OIDC, no token: configure the GitHub Actions trusted publisher for @ciloops/vuln-check on npmjs.com, workflow release.yml).
