FastMCP Dynamic Tools

What it does

This server demonstrates the flexibility of the FastMCP framework by exposing REST API endpoints as MCP tools dynamically. It allows developers to wrap existing APIs into a standardized protocol for AI assistants without using static decorators.

• get_item: Retrieves specific item details by ID.
• create_item: Adds a new item to the inventory.
• update_item: Modifies an existing inventory item.
• delete_item: Removes an item from the system.
• calculate: Performs basic arithmetic operations.
• health_check: Validates server status.
• echo: A dynamically registered tool that echoes messages.
• server_info: Provides details about the current server instance.
• api_reference: Returns the REST API documentation.
