The 'greet' tool is severely underdeveloped. It has a valid input schema with a 'name' parameter (type: string), but the parameter description is null, violating the requirement that every parameter must have a non-empty description. The tool itself has no description visible in the code, making it impossible for an LLM to determine when or why to call it. The tool does nothing meaningful (just returns a greeting string) and provides no value in a bus management context. This appears to be a placeholder or demo server, not a production tool.

• Add a non-empty description to the 'greet' tool explaining what it does and when to use it (10 - 1024 characters).
• Replace the null description on the 'name' parameter with a clear explanation: e.g., 'The person's name to greet (string, any length)'.
• Document the output schema: specify that the tool returns a string greeting message.
• Replace the placeholder 'greet' tool with actual bus management tools: e.g., 'get_route_schedule', 'list_buses', 'book_ticket', 'check_driver_availability'.
• Add parameter constraints and error handling: validate input types, return actionable error messages if parameters are invalid.
