Review the service's API documentation to identify key endpoints

- **Language**: TypeScript (high-quality SDK support and good compatibility in many execution environments e.g. MCPB. Plus AI models are good at generating TypeScript code

Agents benefit from concise tool descriptions and the ability to filter/paginate results. Design tools that return focused

Balance comprehensive API endpoint coverage with specialized workflow tools. Workflow tools can be more convenient for specific tasks
