Macro for creating an MCP server component

This macro simplifies the creation of MCP server components by automatically generating the necessary handlers and message processing logic.

Example

use mcp_sdk::mcp_server_component;
use serde_json::Value;
 
struct MyTool;
 
impl ToolHandler for MyTool {
    fn handle(&self, params: &Value) -> Result<Value, JsonRpcError> {
        // Handle tool call
        Ok(json!({ "result": "success" }))
    }
     
    fn name(&self) -> &'static str {
        "my_tool"
    }
     
    fn description(&self) -> &'static str {
        "A custom tool"
    }
     
    fn input_schema(&self) -> Value {
        json!({
            "type": "object",
            "properties": {
                "param1": {
                    "type": "string"
                }
            }
        })
    }
}
 
mcp_server_component! {
    tools: [
        MyTool
    ]
}
