This server has 27 tools with significant quality gaps. Most tools lack proper input schemas (only 3-4 fields visible per tool, no type definitions beyond 'string', 'file', 'object', 'array', 'integer', 'boolean'). Descriptions are present but generic (avg ~80 chars, well below the 194-char baseline for A+ tools). Critical issues: (1) No output schemas documented anywhere, LLMs cannot plan downstream calls. (2) Parameter descriptions are minimal ('Username', 'Password') without constraints, formats, or validation guidance. (3) No error handling guidance in any tool description. (4) Sensitive tools (delete_user, delete_tool, remove_mcp_server) lack confirmation/dry-run patterns. (5) Authentication tools (login, logout) expose session state management without clear permission gates. (6) Tool composition is poor, upload_document + query + process_document overlap; register_tool + add_mcp_server + connect_to_server form unclear chains. (7) No idempotency guarantees stated. (8) Naming is inconsistent: 'add_user' vs 'delete_user' (verb_noun), but 'get_current_user' vs 'get_permissions' (inconsistent object naming). Per-tool analysis: upload_document, query, login, logout, get_current_user, get_permissions, add_user, delete_user, register_tool, delete_tool, get_tools, get_tool_briefs, add_mcp_server, remove_mcp_server, get_mcp_servers, connect_to_server, disconnect_from_server, build_bm25_index, search_index, update_index, clean_index, process_document, extract_keywords, analyze_query, assess_content_systematicity, rerank_results, health_check all score 30-45 individually due to missing schemas and weak descriptions.

• Document output schemas for all tools. E.g., query should return {results: [{id, title, content, score}], total_count, next_cursor}. get_tools should return {tools: [{name, description, scope, confirmationRequired}], total}. This enables LLMs to plan multi-step workflows.
• Expand parameter descriptions to 50-100 chars with constraints. E.g., 'Username (3-20 alphanumeric chars, case-insensitive)' instead of 'Username'. Include enums for role, scope, protocol fields. Add format hints for dates (ISO 8601) and URLs.
• Add confirmation/dry-run patterns to destructive tools. E.g., delete_user should accept a 'confirm' boolean parameter (default false) and return a preview of what will be deleted. Alternatively, add a separate 'preview_delete_user' tool.
• Add error handling guidance to tool descriptions. E.g., login: 'Returns 401 if credentials invalid (retryable with correct password). Returns 429 if rate-limited (wait 15 min). Returns 500 if server error (contact admin).' This guides agent recovery.
• Clarify tool composition with dependency hints. E.g., upload_document description: 'Call this first to ingest documents. Then call query() to search them. Use process_document() only if you need to re-analyze a specific file.' Reduce ambiguity about which tools to chain.
