Server has 4 tools with basic descriptions and parameter schemas, but significant gaps limit production readiness. Tool names follow verb_noun convention (email_tool, telegram_tool, signal_tool, get_communication_status), which is good. However, descriptions lack depth on WHEN to use each tool and what distinguishes them. Parameters have types and basic descriptions, but lack constraints (enums, ranges, format specs). Output schemas are not documented, callers cannot predict response structure. Error handling is minimal; no guidance on recovery or retry logic. The email_tool description mentions a hardcoded default recipient ([email protected]), which is a security/privacy concern. Overall, definitions are functional but below production baseline (median 45-55 for community servers; this scores at lower end of that range).

• Document output schemas for all tools. Specify return type (string vs Dict), field names, types, and meanings. E.g. email_tool returns {status: 'sent'|'failed', message: string, timestamp?: ISO8601}.
• Remove hardcoded email address from email_tool description and default. Either require explicit 'to' parameter or inject default via environment variable, not in tool definition.
• Add parameter constraints: timeout 1 - 3600 seconds, message 1 - 4096 chars, recipient must match phone pattern (+\d{10,15}) or group ID format. Use JSON Schema minLength, maxLength, pattern, minimum, maximum.
• Enhance error messages with recovery guidance. E.g. 'Email failed: SMTP timeout. Retry with longer timeout or check RESEND_API_KEY.' Categorize errors as retryable vs fatal.
• Expand get_communication_status description to explain what each service status field means (e.g., 'email: {configured: bool, last_sent: ISO8601?, error?: string}') and when to call it (e.g., 'Call before sending to verify all services are ready').

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
