Documentation

Overview

Package containerregistry implements MCP tools for GitLab container registry operations.

It wraps the GitLab ContainerRegistry service to list project and group repositories, list and delete tags, inspect tag details, and manage container registry protection rules. The package also registers MCP tools and provides Markdown rendering for container registry responses.

Safety Model

Tag and protection-rule deletions are destructive catalog actions. Their ActionSpecs mark that behavior so read-only mode, safe mode previews, and dynamic confirmation handling all see the same metadata.

GitLab API References

The package wraps the GitLab Container Registry API:
