BlogCaster MCP provides 5 tools with reasonable naming and mostly complete schemas. Tool names follow verb_noun convention (getTokenManagementLink, publishPost, getBlogs, updatePost, deletePost). All tools have descriptions between 34-74 characters. Input schemas are present for all tools with typed parameters and enums for platform selection. However, there are significant gaps: (1) Output schemas are completely undocumented, no details on what publishPost, getBlogs, or updatePost return; (2) Error handling descriptions are absent, no guidance on retryability, user-fixable errors, or recovery paths; (3) Parameter descriptions lack detail on constraints, ranges, and validation rules; (4) Tool descriptions do not explain prerequisites, when to call each tool relative to others, or expected return structure; (5) No dry-run or confirmation mechanism for destructive operations (deletePost); (6) Missing parameter 'required' field declarations in schema, unclear which params are mandatory. Naming is solid but descriptions are minimal (10-74 chars vs. baseline 194 chars average for A+ tools), and complete output schemas are missing.

• Add comprehensive output schema documentation for all tools. Example for publishPost: 'Returns {success: boolean, publishedUrls: {hashnode?: string, devto?: string, wordpress?: string}, failedPlatforms?: string[], errors?: {platform: string, message: string}[]}'.
• Expand tool descriptions to 150-250 characters. Explain WHEN to use each tool and what to expect. Example: 'publishPost: Publishes a single markdown post to one or more blogging platforms simultaneously. All platforms must be configured via getTokenManagementLink first. Returns post URLs for successful platforms; partial failures list which platforms failed and why.'
• Add parameter constraints and validation rules in descriptions. Example: 'title: string (1-200 chars, required). contentMarkdown: string (10-100000 chars, required, must be valid markdown). platforms: array of enum [hashnode, devto, wordpress], at least one required.'
• Document which parameters are required vs. optional. Update schemas to include 'required' field: ['title', 'contentMarkdown', 'platforms'] for publishPost.
• Add error handling guidance to tool descriptions. Example: 'If a platform returns 401, token may be expired, call getTokenManagementLink to refresh. Partial failures (some platforms succeed, others fail) return per-platform results; the agent may retry failed platforms separately.'
• Implement dry-run or confirmation for deletePost. Add optional 'dryRun: boolean' parameter. Document: 'If dryRun=true, validates the postId but does not delete. Always pass dryRun=true first to confirm target post before deletion.'
