This server has critical definition gaps. Tool descriptions are present but minimal (10-60 chars, well below the 50-200 char baseline for LLM-optimized descriptions). No parameter descriptions are visible in the schema definitions. No output schemas are documented. Error handling is absent, no guidance on what happens on auth failure, network errors, or publish rejection. The server appears to be a Flask app (app.py) wrapping a Xiaohongshu API client, but the actual tool registration code is not shown, making it impossible to verify if schemas are properly declared in the MCP protocol layer.

• Expand tool descriptions to 80-150 chars. Example: 'check_login_status: Returns whether the user is currently authenticated with Xiaohongshu. Call this before publish_content to verify credentials. Returns {authenticated: boolean, user_id?: string}.'
• Add parameter descriptions to publish_content schema: title (string, 1-100 chars, required), content (string, 1-2000 chars, required), images (array of file paths, max 9 items, optional), tags (array of strings, max 5 tags, optional).
• Document output schemas for all tools. Example: get_login_qrcode returns {qr_code_url: string, expires_at: ISO8601_string, session_id: string}.
• Add error handling guidance: 'If publish_content returns 401, call get_login_qrcode to re-authenticate. If it returns 400, validate that images exist and tags are under 30 chars each.'
• For publish_content, add a dry_run parameter (boolean, default false) to preview content before publishing, reducing accidental posts.

Inferred effective spec: <=2025-11-25.

• Relies on Stateful initialize / Mcp-Session-Id (removed; protocol is stateless) - make each request self-contained
