Media Hunter MCP demonstrates solid definition quality with comprehensive schemas, detailed parameter descriptions, and proper tool annotations. All 5 tools have explicit input schemas with type constraints and enums. Descriptions are substantive (100-300+ chars) and explain WHEN to use each tool. Output schemas are fully documented with structured POST and DOWNLOAD_DATA_SCHEMA definitions. Tool names follow verb_noun pattern (media_hunter_search, media_hunter_download). However, some parameter descriptions are verbose and could be more concise for LLM parsing. Error handling guidance is present but could be more explicit about recovery paths. Chinese descriptions may reduce LLM comprehension in some contexts.

• Condense parameter descriptions to 50-100 characters in English. Current descriptions (100-200+ chars) waste tokens. Example: 'site' param is 100+ chars; reduce to 'Target site: e621, rule34, ehentai, or pixiv'.
• Add explicit error recovery guidance in tool descriptions. Document what to do when media_hunter_download returns partial_download or media_hunter_check detects invalid credentials.
• Expand media_hunter_check input schema to document whether it auto-detects all sites or accepts optional site parameter for targeted checks.
• Add a dry-run parameter to media_hunter_download and media_hunter_download_url so agents can preview downloads before committing (e.g., dry_run=true returns file list without writing).
• Provide English translations or English-primary descriptions. Chinese descriptions reduce LLM comprehension in non-Chinese-trained models and complicate prompt engineering.
