IAC Audit Pack

Unbearable IaC Audit Pack — all four audit Actors under one MCP endpoint. Snyk-comparable scope at a fraction of the cost. Pay-per-event — only billed when a tool is actually called.

64 checks. 20 categories. 4 audit engines. 1 MCP endpoint.

What's included

Package	Checks	Categories	Primary tool
Docker Compose audit	25	9	audit_compose
Dockerfile audit	19	5	audit_dockerfile
GitHub Actions audit	21	6	audit_github_actions
HU Postcode Validator	5 tools	—	validate_postcode, lookup_city, …

Plus two bundle-only tools:

• audit_all — paste a dict of filenames → content; auto-detects Dockerfile, compose, and workflow files and runs the right audit on each
• list_all_checks — full cross-package check catalog in one call

Architecture

Package-import (not proxy): all four sub-packages are bundled directly into the Actor image. Single cold start, single billing rail, no cross-Actor latency. See DESIGN.md for the full rationale.
