This server exhibits severe definition quality issues across multiple dimensions. Only 2 of 6 tools have weather-related functionality; the other 4 (access-mysql, get_last_transaction, top_expense_by_category, create_expense) are unrelated financial/database tools mixed into a weather server, indicating architectural confusion. Tool descriptions are present but minimal (10-80 chars, below the 194-char baseline). Schemas are partially defined via Zod but lack comprehensive parameter descriptions. The access-mysql tool exposes dangerous SQL query execution with no input validation, sanitization, or permission gating. Tool naming is inconsistent (kebab-case vs snake_case). Error handling is minimal, most tools return generic failure messages without recovery guidance.

• Split this into two separate MCP servers: one for weather (get-alerts, get-forecast) and one for expense tracking (get_last_transaction, top_expense_by_category, create_expense, access-mysql). Each server should have a single, clear domain.
• For access-mysql: REMOVE this tool entirely or replace it with domain-specific, pre-built queries (e.g., get_expense_summary, get_transaction_by_id). Never expose raw SQL to agents. If you must support dynamic queries, use parameterized prepared statements with strict allowlists and permission checks.
• Standardize all tool names to snake_case (get_alerts, get_forecast) for consistency with the financial tools. This reduces LLM confusion when selecting tools.
• Expand error messages to include recovery guidance: 'Failed to retrieve alerts for CA. This location may not be supported by the NWS API (only US locations). Try a different state code.' Reference pattern:recovery-guide.
• Add parameter constraints and enums: for transaction_type, define enum ['expense', 'income']; for limit, set min=1, max=100 with default=3. Document these in parameter descriptions, not just Zod schemas.
