Scored across 8 tools
Most tools have distinct purposes, but update-metadata and update-metadata-ui both update metadata via different methods, which could cause confusion. The descriptions help differentiate, but an agent might still misselect.
Tool names consistently use lowercase with hyphens, but there is a mix of verbs (cancel, publish, upload) and nouns (status, deploy-percentage). The hyphenation pattern is consistent.
8 tools cover the core operations for Chrome Web Store item management without being overwhelming. The count is well-scoped for the server's purpose.
The set covers publishing workflow well, but misses important operations: creating new items (must use dashboard), listing items, and deleting. These gaps could hinder agents needing full lifecycle management.
