# Dockerfile Security & Quality Audit (`unbearable_dev/dockerfile-audit`) Actor Hadolint-grade Dockerfile audit, MCP-native. 18+ checks across 5 categories (base image, instructions, security, efficiency, secrets) with severity, line numbers, remediation, and fix snippets. Pay-per-event. Call from Claude Desktop, Cursor, n8n, or any MCP client. Built by Unbearable TechTips. - **URL**: https://apify.com/unbearable\_dev/dockerfile-audit.md - **Developed by:** [Noel Himer](https://apify.com/unbearable_dev) (community) - **Categories:** Developer tools, Automation, MCP servers - **Stats:** 1 total users, 0 monthly users, 0.0% runs succeeded, NaN bookmarks - **User rating**: No ratings yet ## Pricing from $20.00 / 1,000 docker file audit calls This Actor is paid per event and usage. You are charged both the fixed price for specific events and for Apify platform usage.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## 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 TechTips](https://github.com/UnbearableDev).** Pay-per-event pricing — only billed when a tool is actually called. --- ### 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. ### Pricing | Event | USD | |-------|-----| | Any audit / check_* tool call | $0.02 | | `list_checks` discovery | $0.005 | ### Example response (truncated) ```json { "summary": { "total_findings": 6, "by_severity": {"high": 2, "medium": 2, "low": 2, "info": 0} }, "findings": [ { "id": "DFA-021", "category": "security", "severity": "high", "instruction": "USER", "line_number": 3, "title": "USER root set explicitly", "description": "...", "remediation": "Switch to a non-root UID after any root-required RUN steps.", "fix_dockerfile_snippet": "USER 10001:10001", "references": ["CIS-Docker-4.1"] } ] } ```` ### Connecting from Claude Desktop ```json { "mcpServers": { "dockerfile-audit": { "transport": "streamable-http", "url": "https://YOUR-ACTOR-URL.apify.actor/mcp" } } } ``` ### Limits - **Dockerfile size:** 200 KB cap per audit - **URL fetch:** 5s timeout, max 3 redirects, HTTPS only - **Session timeout:** 5 minutes of inactivity ### What's NOT covered (yet) - Live image vulnerability scanning (use Trivy / Grype for that) - Multi-stage build optimization analysis (DFA-004 / DFA-005 — roadmapped) - Compose-file audit (separate MCP: [`docker-compose-audit`](https://apify.com/unbearable_dev/docker-compose-audit)) ### Sibling MCPs from Unbearable TechTips - **[`docker-compose-audit`](https://apify.com/unbearable_dev/docker-compose-audit)** — same pattern for `docker-compose.yml` - **[`hu-postcode-validator`](https://apify.com/unbearable_dev/hu-postcode-validator)** — Hungarian postcode lookup ### Source / contact Issues and ideas: `unbearabledev@gmail.com` or the GitHub org [`UnbearableDev`](https://github.com/UnbearableDev). # Actor input Schema ## Actor input object example ```json {} ``` # API You can run this Actor programmatically using our API.
