Scored across 5 tools
Each tool has a clearly distinct purpose targeting specific S3 operations: listing buckets, listing objects, uploading, reading, and deleting. There is no overlap in functionality, making tool selection straightforward for an agent.
All tools follow a consistent 's3_verb_noun' pattern with snake_case, using clear verbs like list, put, read, and delete. This uniformity makes the tool set predictable and easy to navigate.
With 5 tools, the server is well-scoped for basic S3 operations, covering essential actions without being overwhelming. Each tool serves a distinct and necessary function in the domain.
The tool set covers core CRUD operations for S3 objects (create, read, delete, list) and bucket listing, but lacks operations like copying objects, managing bucket policies, or handling multipart uploads. However, the included tools support fundamental workflows effectively.
