Server has 20 tools with complete input schemas and descriptions. Naming follows verb_noun convention consistently (list_, get_, create_, update_, delete_, approve_). Descriptions are present but generic (avg ~60 chars, below 194-char baseline). Critical gaps: no output schemas documented, no error handling guidance, no parameter constraints (enums), no pagination details despite list tools, complex nested schemas lack field-level descriptions. Security concern: no mention of API key injection or permission gates. Composition is sound (single responsibility per tool), but parameter descriptions are minimal, e.g., 'The UUID of the post to retrieve' lacks context on format or where to obtain UUIDs.

• Document output schemas for all tools. Specify returned fields, types, and which IDs are needed for chaining (e.g., post_id, account_id, media_id). Use a separate 'outputSchema' field or inline in description.
• Add field-level descriptions to nested objects. For 'versions' array in create_post/update_post, document what account_id, is_original, content.body, content.media, and content.urls represent and accept.
• Add enums for constrained parameters: status in list_posts (e.g., 'draft', 'scheduled', 'published', 'failed'), type in list_media (e.g., 'image', 'video', 'audio'), timezone (IANA list or common zones).
• Add error handling guidance to destructive tools (delete_post, delete_media, delete_tag). E.g., 'If post not found, return 404 with message: "Post {postUuid} not found. Check post UUID and try list_posts to find it."'
• Document pagination defaults and limits in list_posts and list_media. E.g., 'Default limit=20, max=100. Returns total_count and next_cursor for pagination. If no results, return empty array and total_count=0.'
