Skeleton MCP Server

""" Example API Module This module demonstrates how to structure API functions that will be registered as MCP tools. Replace this with your actual API implementation. Each function should: 1. Have a clear docstring explaining what it does 2. Use type hints for parameters and return values 3. Handle errors gracefully 4. Return structured data (dicts, lists, etc.) """ from typing import Any # In a real implementation, you would import and use the API client: # from ..client import get_client # from ..types import ItemData, ItemListResponse # For the skeleton, we use mock data MOCK_ITEMS: dict[str, dict[str, Any]] = { "item-1": { "id": "item-1", "name": "Example Item 1", "description": "This is a sample item", "created_at": "2024-01-01T00:00:00Z", "updated_at": "2024-01-01T00:00:00Z", }, "item-2": { "id": "item-2", "name": "Example Item 2", "description": "Another sample item", "created_at": "2024-01-02T00:00:00Z", "updated_at": "2024-01-02T00:00:00Z", }, } async def list_items( page: int = 1, page_size: int = 10, filter_name: str | None = None, ) -> dict[str, Any]: """ List all items with optional filtering and pagination.
