This server has a single tool (generateRandomNumber) with critical definition gaps. The tool lacks parameter descriptions entirely, has a minimal input schema with no documented properties, and provides only a basic description in Portuguese. The server does register the tool explicitly with schema and description in server.js, but the definition quality is far below production standards. No parameter validation, no error handling guidance, and no output schema documentation. This is representative of a beginner-level implementation.

• Expand the tool description to 100-200 characters, explaining when to call it (e.g., 'Use this tool whenever you need a random integer between 1 and 100, such as for games, random selection, or testing purposes.'). Write in English for LLM clarity.
• Document the output schema explicitly: define that the tool returns an object with a field 'randomNumber' (integer, 1-100), and return structured JSON from the tool instead of embedding the number in a text string.
• Add explicit error handling: document what happens if random generation fails (unlikely, but specify the error response) and guide the LLM to retry or handle gracefully.
• Rename the tool to 'generate_random_number' to match snake_case naming convention used in production MCP servers.
• Add a 'range_min' and 'range_max' parameter (optional, with defaults 1 and 100) to make the tool more flexible and demonstrate proper parameter description and schema composition.
• Ensure all responses are structured JSON objects with documented fields, not wrapped in descriptive text strings. Return {"randomNumber": 42} not 'Random number generated: 42'.
