Server has 5 tools with basic schemas and descriptions, but significant quality gaps. Tool naming is inconsistent (get-alerts, get-forecast are clear; register-notification is vague about what it registers; get-user-notifications lacks verb clarity). Descriptions are present but generic (10-194 chars, below the 50-200 char LLM-optimized baseline). Parameters have types and descriptions, but several lack constraints or format guidance. Critical issue: tool descriptions do not match functionality, get-alerts and get-forecast claim to be weather tools but register-notification, get-user-notifications, and get-latest-token-price are cryptocurrency price alerts, creating semantic confusion. No output schemas documented. Error handling is minimal (generic try-catch blocks with no recovery guidance). No tool annotations (readOnlyHint, destructiveHint, idempotentHint). Security concern: register-notification accepts session_id as a parameter, which could leak into logs.

• Rename server and tools to reflect actual domain. Either split into two servers (weather + crypto-alerts) or rename to 'notification-mcp' and clarify tool purposes in descriptions.
• Document output schemas for all tools. Specify what fields each response contains, their types, and which are required. Example: 'Returns {alerts: [{event, area, severity, status, headline}], count: number}'.
• Expand tool descriptions to 50-200 characters. Include WHAT the tool does, WHEN to use it, and WHAT it returns. Example: 'Fetch active weather alerts for a US state. Returns event type, affected area, severity, and headline. Use before get-forecast to warn of hazards.'
• Move session_id to server-side configuration or request headers. Do not expose session identifiers as tool parameters, they are sensitive and leak into logs. Use environment variables or MCP request metadata instead.
• Add structured error responses with recovery guidance. Instead of 'Failed to register alert: <error>', return '{error: "invalid_token", message: "Token symbol not recognized. Call get-latest-token-price to see available tokens.", retryable: false}'.
