Macro mcp_text 

mcp_text!() { /* proc-macro */ }

Helper macro for creating MCP ContentBlock structures (advanced usage)

Note: Most tool functions should simply return String using format!(). Only use mcp_text!() when manually building CallToolResult structures.

Common Usage (90% of cases) ✅

use turbomcp::prelude::*;

#[tool("Say hello")]
async fn hello(&self, name: String) -> turbomcp::McpResult<String> {
    Ok(format!("Hello, {}!", name))  // ✅ Use format! for #[tool] returns
}

Advanced Usage (rare) ⚠️

let name = "world";
let content_block = mcp_text!("Hello, {}!", name);
// Use in manual CallToolResult construction
