Description
Everytime run the mcp server i made get this issue.
//main.rs
mod handler;
mod tools;
mod watch_cursor;
mod desktop;
mod tree;
use rmcp::{
ServiceExt,
transport::stdio,
};
use handler::WindowsMCP;
#[tokio::main]
async fn main()->Result<(),Box<dyn std::error::Error>> {
let service=WindowsMCP::new();
let server=service.serve(stdio()).await?;
server.waiting().await?;
Ok(())
}
// handler.rs
use rmcp::{
handler::server::router::tool::ToolRouter,
model::{
Implementation,
ProtocolVersion, ServerCapabilities, ServerInfo
},
ServerHandler,tool_handler
};
pub struct WindowsMCP {
pub tool_router:ToolRouter<Self>
}
#[tool_handler]
impl ServerHandler for WindowsMCP {
fn get_info(&self) -> ServerInfo {
ServerInfo {
server_info:Implementation {
name: "Windows-MCP".to_string(),
version: "0.1.0".to_string(),
},
protocol_version: ProtocolVersion::V_2025_03_26,
instructions: Some("Lightweight MCP server for computer use in Windows".to_string()),
capabilities: ServerCapabilities::builder().enable_tools().build(),
..Default::default()
}
}
}
But if I made the same mcp server in python no issuses
