Overview

Description from the maker (original English)

Hadolint-grade Dockerfile audit — 19 checks: secrets, privileges, supply chain, hygiene.

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 in the cloud
Transport: Streamable HTTP
Category: Other
You need to fill in: Authorization

Install

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

Before you install

Basic checks: 1 of 1 passed
Runs on the maker’s server: what you ask it goes through their server.
You fill in yourself: Authorization

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

You need

Runs in the cloudNothing to install; it connects over the internet

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

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

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http dockerfile-audit https://unbearable-dev--dockerfile-audit.apify.actor/mcp --header 'Authorization: your-value'

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": {
    "dockerfile-audit": {
      "url": "https://unbearable-dev--dockerfile-audit.apify.actor/mcp",
      "headers": {
        "Authorization": "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": {
    "dockerfile-audit": {
      "type": "http",
      "url": "https://unbearable-dev--dockerfile-audit.apify.actor/mcp",
      "headers": {
        "Authorization": "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 address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

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

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

Common questions

Is Dockerfile Audit 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: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, Zendesk

Dockerfile Security & Quality Audit

Hadolint-grade Dockerfile audit as an MCP server. 18+ checks across 5 categories, every finding ships with severity, line number, remediation text, and a copy-paste Dockerfile snippet.

Built by [Unbearable Labs](https://github.com/UnbearableDev). Pay-per-event pricing — only billed when a tool is actually called.

Available on

Apify Actor Store — primary, metered usage (PPE)
MCPize — *pending submission*
MCP.so — *pending submission*
PulseMCP — *pending submission*
Smithery — *pending submission*
Glama — *pending submission*

What it does

Point any MCP-capable client (Claude Desktop, Cursor, n8n, Make, Zapier, custom agents) at this server, hand it a Dockerfile, get back a structured report:

Severity — high / medium / low / info
Line number — exact location in the file
Description — what's wrong and why it matters
Remediation — what to do about it
Fix snippet — Dockerfile syntax you can paste directly

Tools

Tool	Purpose
`audit_dockerfile(dockerfile_content? \	dockerfile_url?, min_severity='low')`	Run all checks
`check_base_image(...)`	FROM/tag/digest/registry checks only
`check_instructions(...)`	CMD form, ADD vs COPY, MAINTAINER, etc.
`check_security(...)`	USER, sudo, chmod 777, curl\	bash, hardcoded secrets, HEALTHCHECK
`check_efficiency(...)`	apt cache hygiene, pip caching
`check_secrets(...)`	ARG with secret-pattern names
`list_checks(category?)`	Browse the full check catalog

Provide exactly one of dockerfile_content (paste the file) or dockerfile_url (HTTPS URL — e.g. GitHub raw).

Check catalog (v1: 18 checks across 5 categories)

ID	Category	Severity	Title
DFA-001	base_image	medium	Image uses :latest tag or no tag
DFA-002	base_image	info	No SHA256 digest pin on FROM
DFA-003	base_image	medium	Untrusted registry
DFA-010	instructions	low	CMD in shell form
DFA-011	instructions	low	ENTRYPOINT in shell form
DFA-012	instructions	info	MAINTAINER instruction is deprecated
DFA-013	instructions	medium	ADD used where COPY would suffice
DFA-020	security	medium	No USER directive (runs as root)
DFA-021	security	high	USER root set explicitly
DFA-022	security	high	sudo invoked in RUN
DFA-023	security	high	chmod 777 in RUN
DFA-024	security	medium	curl\	bash pattern in RUN
DFA-025	security	high	Hardcoded secret in ENV
DFA-027	security	low	No HEALTHCHECK
DFA-030	efficiency	low	apt-get update without install
DFA-031	efficiency	low	apt-get install without --no-install-recommends
DFA-032	efficiency	low	pip install without --no-cache-dir
DFA-040	secrets	medium	ARG with secret-pattern name

Use list_checks to get the canonical, up-to-date catalog.
