This is a template repository, not a production MCP server. Tool definitions are present but minimal. The 5 tools have basic descriptions (10-50 chars, below the 50-200 char baseline for LLM optimization) and incomplete parameter documentation. Schemas are visible in TypeScript (tools.ts) and Python (tools.py) but lack depth: no enums for constrained inputs, no output schema documentation, no error handling guidance. The 'process' tool uses an enum for 'format' (good), but others like 'search' and 'get_data' accept free-form strings with no validation hints. No tool declares permissions, audit trails, or recovery paths. Naming is generic ('search', 'process', 'get_data'), acceptable but not verb-specific enough to disambiguate intent. This is a starter template, not production-grade.

• Expand tool descriptions to 50-200 characters. Example: 'search' → 'Search for items by query string. Returns up to 20 results ranked by relevance score. Use when you need to find specific items by keyword.'
• Document output schemas explicitly. For 'search', specify: returns array of {id: string, title: string, score: number}. For 'get_data', specify: returns {id, name, status, updated_at}.
• Add parameter constraints and format hints. For 'calculator', add: 'expression: mathematical expression (e.g., "2 + 2"), allowed chars: 0-9+-*/.() only, max 100 chars'.
• Implement error classification and recovery guidance. For 'calculator', return: 'Invalid expression: got "2 ++ 2", allowed operators are +, -, *, /, parentheses. Try again with valid syntax.'
• Add tool annotations via MCP SDK. Mark 'search', 'get_data', 'web_search', 'calculator' as readOnlyHint=true; mark 'process' as destructiveHint=false (it's safe but transforms data).
