🚀 Getting Started

  1. Installation 
    [dependencies]
mcp-rs = "0.1.0"
  2. Basic Usage 
    use mcp_rs::{
    server::McpServer, 
    config::Config,
    handlers::wordpress::WordPressHandler
};
   
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Load configuration
    let config = Config::load("mcp-config.toml")?;
       
    // Create server
    let mut server = McpServer::new();
       
    // Add WordPress handler if configured
    if let Some(wp_config) = config.wordpress {
        let handler = WordPressHandler::new(wp_config);
        server.add_handler("wordpress", Box::new(handler));
    }
       
    // Start server
    server.serve(config.server.address()).await?;
    Ok(())
}
  3. Configuration 
    # mcp-config.toml
[server]
host = "127.0.0.1"
port = 8080
   
[wordpress]
url = "https://your-wordpress-site.com"
username = "your_username"
password = "your_application_password"
timeout_seconds = 30
