This server has a single tool 'getweatherdata' with minimal definition quality. The tool lacks a proper description (null parameter description), has an input schema with only type information and no parameter validation constraints. The parameter description is explicitly null, violating the baseline requirement that 100% of A+ tool params have descriptions. The tool name is acceptable but generic. Error handling is present in the implementation but not documented in the tool definition. Output is returned as a JSON string rather than structured typed objects.

• Add a non-empty tool description (10 - 200 chars): e.g., 'Retrieves current weather data for Indian cities including temperature, forecast, humidity, and wind speed. Call this when the user asks about weather conditions.'
• Add a description to the 'city' parameter: e.g., 'Name of the Indian city (e.g., pune, mumbai, delhi, bangalore). Must be one of the supported cities.'
• Replace the generic string type with an enum constraint listing all 50 supported cities: z.enum(['pune', 'mumbai', 'delhi', ...]), this self-documents valid values and prevents hallucinated city names.
• Document the output schema in the tool definition or response comments: specify that successful responses return {temperature, forecast, humidity, windSpeed, condition} and error responses return {error: true, message: string}.
• Enhance error handling to follow the recovery-guide pattern: instead of returning {error: true, message: '...'}, return a structured response that suggests the closest matching city name or lists a few valid alternatives.
• Validate city names case-insensitively inside the tool (currently done), but add the enum constraint to the schema so LLMs know the valid set upfront.
