Bihar AgMCP exhibits significant definition quality gaps. Tool naming is inconsistent (duplicate 'get_crop_calendar' and 'generate_weather_alert' across files). Descriptions vary widely in quality, some are adequate (generate_weather_alert: 'Generate comprehensive weather alerts...'), but many lack specificity or are generic. Parameter descriptions are present but often minimal. Critical issue: API keys exposed as parameters (get_accuweather_current_conditions, get_google_weather_current_conditions, generate_weather_alert) violates secret-injection pattern. Output schemas are not documented. Error handling is absent, no recovery guidance or categorization. Tool composition shows poor separation of concerns (generate_weather_alert appears twice with different signatures). No pagination support despite tools returning lists. Baseline: 549 production tools average 194 chars for descriptions; this server's descriptions range 30-150 chars, many at the low end.

• Move API keys (OpenAI, AccuWeather, Google) to environment variables. Inject them server-side. Remove api_key parameters from tool signatures.
• Consolidate duplicate tools: merge get_crop_calendar definitions into one with union of both parameter sets; merge generate_weather_alert into a single definition with all required fields.
• Document output schemas for all tools. Use JSON Schema format. Example: 'Returns {type: object, properties: {district: string, alerts: array of {crop: string, severity: string, recommendation: string}}}'.
• Add error handling: validate district names against enum, return 'District not found. Valid options: [list]' instead of silent failure. Categorize errors as retryable (network timeout) vs user-fixable (invalid district).
• Replace untyped 'alert_data' object parameter with explicit fields: crop (string), location (string), temperature (number), humidity (number), rainfall (number). Add descriptions for each.
