This server has mixed quality. Tool names are action-verb clear and well-formed (create_blog_post, patch_blog_post, get_all_tags). Descriptions are present in Chinese and broadly adequate (ranging 15 - 186 chars). However, schemas lack several critical elements: no output schemas are documented anywhere; parameters have descriptions but some are sparse; no error handling guidance is visible; no input validation or recovery paths are specified. The tools themselves are reasonably well-defined in JSON Schema with proper type declarations and nested object structures for the batch tool. But the absence of documented output schemas, missing error handling patterns, and lack of tool annotations (destructiveHint, idempotentHint) for write operations significantly limit production readiness. A blog creation tool that modifies state (create_blog_post, patch_blog_post) should declare destructiveHint or at minimum warn about side effects, neither is present.

• Add output schemas to each tool definition. Document the structure of successful responses (e.g., { slug: string, message: string, url: string }) so agents can extract chaining IDs and plan multi-step operations.
• Add toolAnnotations to write operations: create_blog_post and patch_blog_post should declare destructiveHint=true to warn agents about permanent side effects.
• Enhance error handling with recovery guidance. Instead of 'Failed to create blog post', return 'Failed to create blog post (invalid date format). Dates must be ISO 8601, e.g., 2024-01-15. Check the slug for uniqueness via get_all_tags().'
• Add JSON Schema format and bounds constraints: date parameter should use 'format: date-time'; readTime should declare 'minimum: 1, maximum: 1440' (1-1440 minutes = 1 day max).
• For create_multiple_blog_posts, return per-item results with explicit success/failure reasons so agents can retry only failed articles: { articleIndex: 0, slug: '...', success: true } or { articleIndex: 2, slug: '...', success: false, reason: 'Slug already exists' }.
• For get_all_tags, add optional limit and offset parameters (default limit=50). Return { tags: [...], total: 147, hasMore: true } so agents can paginate large tag lists.
• Document the Blog API contract (blogClient methods), currently hidden from agents. Expose error states (e.g., 'slug must be unique', 'title cannot exceed 500 chars') as schema validation or tool-level error messages.
