This server has 4 tools with minimal viable definitions. All tools have basic descriptions and input schemas, but descriptions are generic and lack actionable context. No parameter descriptions exist, schemas show type info but no descriptions field is visible in the input objects. Tool names are action-starting (add, magic_8_ball, long_task, error_tool) but lack clarity on when to use each. The 'magic_8_ball' description explicitly states '(Question is ignored)' which is unusual and suggests poor UX design. Schema structures are present but parameters lack descriptive text that would help an LLM understand purpose and constraints. Error handling is minimal, error_tool exists to test errors, but there's no guidance in descriptions on recovery paths. No tool annotations (readOnlyHint/destructiveHint) are visible. Overall, these are demo/toy tools that would not pass production code review.

• Add description field to each parameter in the JSON schema. Example for 'add': {"a": {"type": "integer", "description": "First integer value to add (range: -2147483648 to 2147483647)"}, "b": {"type": "integer", "description": "Second integer value to add (range: -2147483648 to 2147483647)"}}}
• Rewrite tool descriptions to be 50-200 characters and answer: What does it do? When should I call it? Example for 'add': 'Adds two integers and returns the sum. Use this when you need simple arithmetic. Returns the integer result.'
• Remove useless parameters: 'magic_8_ball' explicitly states '(Question is ignored)', either use the question to seed randomness or remove it. If removed, update description to 'Returns a random Magic 8-Ball answer. Useful for playful responses when a user wants guidance.'
• Rename 'long_task' to 'simulate_async_work' or 'wait_completion' with description: 'Simulates an async task that completes after a delay. Useful for testing timeout behavior. Returns completion status.'
• Rename 'error_tool' to 'test_error_recovery' with description: 'Intentionally raises an error for testing agent error handling. Pass any message string. Useful only in test/demo scenarios, do not use in production.'
• Add tool annotations to schema (fastmcp support required): Mark all four tools with 'readOnlyHint: true' since they are idempotent and side-effect-free.
• Document return types in descriptions: E.g. 'Returns: integer sum of a and b' for add tool, 'Returns: string with a random Magic 8-Ball answer' for magic_8_ball.
