Use when analyzing .NET applications from Microsoft Container Registry (MCR) images without running containers.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# MCR Container Image Analysis Extract and analyze .NET assemblies from Microsoft Container Registry images without executing any container code. Uses pure HTTP—no Docker required. Load the `vuln-assessment-methodology` skill alongside this one for severity calibration, disprove-first discipline, and reporting standards. ## When to Use MCR Tools Use MCR tools when: - Target is an MCR image reference (e.g., `dotnet/aspnet:8.0`, `azure-functions/dotnet:4`) - You need to analyze a specific .NET runtime version - Investigating Azure/Microsoft container-based services Use standard `dotnet_*` tools directly when you already have DLL/EXE files on disk. ## Quick Start ``` mcr_search_repositories(query="dotnet") # find repos mcr_list_tags(repository="dotnet/aspnet", filter_pattern="8.0") # list versions mcr_pull_and_extract(image="dotnet/aspnet:8.0") # extract DLLs dotnet_scan_binaries(path="~/workspace/mcr/dotnet_aspnet_8.0") # analyze ``` ## Tools | Tool | Purpose | |------|---------| | `mcr_search_repositories(query)` | Search ~3,200 MCR repos by name | …

How to install
mdr add dreadnode/capabilities/mcr-analysis@sha256:eeefbe9d2b3bf841The line at the top of this page pins the label git:20260605.9818bab, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
