This server has significant definition quality gaps across all three tools. Two tools (add, getHardwareInfo) are defined in TypeScript with proper registration, but the third (search_eva_content) is defined in a separate Python file using FastMCP without visible explicit registration in the primary codebase. The add tool has a critical logic bug (returns a + b + 1 instead of a + b), suggesting inadequate testing. Descriptions vary in quality but all are under 200 characters. Parameter descriptions are minimal. No output schemas are documented. Error handling is absent, no guidance for recovery, categorization, or actionable error messages.

• Fix the add tool: change 'a + b + 1' to 'a + b'. Verify with unit tests.
• Add parameter descriptions to the add tool inputSchema. Example: {"a": {"type": "number", "description": "The first addend (e.g. 5)"}, "b": {"type": "number", "description": "The second addend (e.g. 3)"}}
• Document output schemas for all tools. Example for add: 'Returns {"content": [{"type": "text", "text": "<sum as string>"}]}'.
• Consolidate server definitions. Either move search_eva_content to alex-mcp.js using the TypeScript SDK, or launch a separate Python MCP server if tools are intentionally split.
• Add error handling with recovery guidance. Example: if SERPER_KEY is missing, return 'Error: SERPER_KEY environment variable not set. Please configure your deployment with a valid Google Serper API key.'
• Extend getHardwareInfo description to include what hardware details are returned and when to use this tool (e.g. 'Call this to check system resources before allocating compute-intensive tasks').
• Add rate limiting or timeout controls to search_eva_content to prevent runaway API calls.
• Implement request validation: validate that search_eva_content query is non-empty and under a reasonable character limit (e.g. 500 chars) to prevent token abuse.
