Module plugin 

Plugin system for dynamically loading and managing MCP tools, resources, and prompts.

The plugin system allows you to:

• Load tools/resources/prompts from external libraries
• Hot reload plugins during development
• Create a plugin ecosystem with shareable components
• Sandbox untrusted plugins with WASM

Example

use mcp_kit::prelude::*;
use mcp_kit::plugin::{McpPlugin, PluginManager};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let mut plugin_manager = PluginManager::new();
     
    // Load plugins
    plugin_manager.load_from_path("./plugins/weather.so")?;
     
    let server = McpServer::builder()
        .name("plugin-server")
        .version("1.0.0")
        .with_plugin_manager(plugin_manager)
        .build()
        .serve_stdio()
        .await?;
     
    Ok(())
}
