Each tool has a clearly distinct purpose with no overlap: fetch_blob retrieves specific blobs, fetch_manifest gets manifests, list_referrers shows referrers, list_repositories lists repositories, list_tags lists tags, list_wellknown_registries lists registries, and parse_reference parses reference strings. The descriptions make it easy to differentiate between these operations.

All tools follow a consistent verb_noun naming pattern (e.g., fetch_blob, list_repositories, parse_reference) using snake_case throughout. This predictability makes it easy for agents to understand and select the right tool based on the action and resource.

With 7 tools, this server is well-scoped for its purpose of interacting with container registries and OCI artifacts. Each tool serves a specific function, such as fetching, listing, or parsing, without redundancy, making the count appropriate and manageable.

The tool set covers core operations for registry interaction, including fetching, listing, and parsing, which supports common workflows. However, there are minor gaps, such as the lack of tools for pushing or deleting artifacts, which might require workarounds for full lifecycle management.
