## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-17.

- **Supply Chain Security**: 0/100
  - No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.
  - Known CVEs could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.
  - Install-script risk not yet assessed.
  - Dependency health could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.
- **Provenance & Transparency**: 100/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to basitalisandhu/dev-mcp-servers).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 3 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 59/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 633 tokens (~211/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 94/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 83% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## MCP tools (3)

### `lint_dockerfile` (~224 tokens)

Lint a Dockerfile

Parse a Dockerfile (comments, escape directive, line continuations, heredocs, multi-stage builds) and return findings sorted by severity with line numbers and fixes. Checks: final stage running as root, base images without a tag or with :latest, images without a digest, credential-like names in ENV or ARG, credential literals in RUN, missing HEALTHCHECK, apt-get install without list cleanup or --no-install-recommends, apt-get upgrade, apk add without --no-cache, pip without --no-cache-dir, ADD for plain files or remote URLs, curl piped to a shell, sudo, relative WORKDIR, repeated CMD or ENTRYPOINT, shell-form CMD, EXPOSE 22, MAINTAINER, copying the whole build context, and COPY after USER without --chown. Pass ignore to silence rule ids.

Input parameters:

- `content` (string): Dockerfile text. Alternative to path.
- `ignore` (array): Rule ids to skip.
- `path` (string): Path to a local Dockerfile (up to 1048576 bytes).

### `parse_dockerfile` (~93 tokens)

Parse a Dockerfile

Return the Dockerfile's instructions in order (instruction keyword, arguments with continuations joined, start and end line, stage index) and its build stages (index, AS name, base image, line), plus the escape character in effect.

Input parameters:

- `content` (string): Dockerfile text. Alternative to path.
- `path` (string): Path to a local Dockerfile (up to 1048576 bytes).

### `explain_rule` (~144 tokens)

Explain a lint rule

Describe one lint rule: its default severity, what it detects and how to fix it. Rules: root-user, latest-tag, unpinned-digest, secret-in-env, secret-in-arg, secret-literal, no-healthcheck, apt-no-cleanup, apt-no-recommends, apt-upgrade, apk-no-cache, pip-no-cache, add-for-copy, add-remote, curl-pipe-shell, sudo, workdir-relative, multiple-cmd, shell-form-cmd, expose-ssh, maintainer-deprecated, copy-whole-context, copy-chown-missing, empty-dockerfile, from-missing.

## Common questions

### What is the Dockerfile Lint MCP server?

Dockerfile Lint is an MCP server listed in the public MCP registry as io.github.basitalisandhu/mcp-dockerfile-lint. Lint Dockerfiles for root users, latest tags, secrets in ENV or ARG, missing HEALTHCHECK and more. This page covers its container image (ghcr.io/basitalisandhu/mcp-dockerfile-lint).

### Is the Dockerfile Lint MCP server safe to use?

Dockerfile Lint scores 50 out of 100 on VerifyMCP. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Dockerfile Lint MCP server expose?

Dockerfile Lint exposes 3 tools: lint_dockerfile, parse_dockerfile, explain_rule. Their descriptions and schemas cost roughly 461 tokens of context every time the server is loaded.

### Is the Dockerfile Lint MCP server still maintained?

Dockerfile Lint is still listed as active in the MCP registry. We last reached this channel on 17 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Dockerfile Lint MCP server under?

Dockerfile Lint declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
