Scored across 6 tools
Each tool targets a distinct operation: add, get all, query, update, delete, and list files. There is no overlap in purpose; even get_json_objects and query_json_objects are clearly different (retrieve all vs. filter by properties).
All tool names follow a consistent verb_noun pattern: add_json_object, get_json_objects, query_json_objects, update_json_object, delete_json_object, list_json_files. The use of singular/plural is logical (action on single vs. multiple).
Six tools is well-scoped for a JSON file management server, covering essential CRUD operations plus query and file listing without unnecessary bloat.
The core CRUD lifecycle is covered: add, get, update, delete, plus query and list files. A minor gap is the lack of a dedicated get-by-index or file deletion, but these can be worked around with existing tools.
