Struct Tool

pub struct Tool {
    pub name: String,
    pub description: String,
    pub input_schema: Option<Value>,
    pub output_schema: Option<Value>,
}

use mcp_runner::client::Tool;

let tool = Tool {

        "type": "object",
        "properties": {

                "description": "The URL to fetch data from"
            }
        },
