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

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

Check catalog (v1: 18 checks across 5 categories)

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