This server has critical definition quality issues. The single tool 'operate' has a reasonable description but severely underdeveloped input/output schemas. The input schema is present but minimal, parameters lack proper type constraints and validation guidance. Output schema is completely undocumented in the code. The tool violates single-responsibility principle by handling four disparate business areas (revenue, hiring, product, marketing) in one function. No error handling, no confirmation patterns for destructive operations, and the health_score calculation logic exposes internal implementation details to the agent instead of abstracting them. The description is verbose but does not clarify WHEN to use this vs. other tools or what the actual output structure is.

• Split 'operate' into four separate tools: analyze_revenue_health, evaluate_hiring_metrics, assess_product_health, review_marketing_performance. Each should focus on one business area with its own parameters and logic.
• Document the output schema explicitly in the MCP tool definition. Include field names, types, and descriptions: {actions: string[], priority: 'LOW'|'MEDIUM'|'HIGH', health_score: number (0.0-1.0)}.
• Add enum constraint to business_area parameter: ['revenue', 'hiring', 'product', 'marketing']. Remove the fallback logic that accepts arbitrary strings.
• Replace current_metrics generic object with structured, named parameters specific to each business area. E.g., for revenue: mrr_growth_pct (number, 0-100), churn_rate_pct (number, 0-100), overdue_invoices (integer, >=0). Document expected ranges and what happens if values are missing.
• Clarify in the tool description whether these operations are simulated recommendations or actual business actions (e.g., does 'Pause underperforming ads' actually pause them?). Add a state-modification statement if applicable.
• Add error handling and recovery guidance: 'If current_metrics is empty or contains no numeric values, return an error asking the user to provide at least one valid metric.'
• Reduce description length from ~300 chars to 100-150 chars. Focus on WHAT the tool does and WHEN to use it, not exhaustive lists of actions.
• Add parameter descriptions for current_metrics explaining the expected structure, metric names, numeric ranges, and what the tool does if optional metrics are missing.
