Module mcp 

MCP (Model Context Protocol) server framework.

Provides a JSON-RPC 2.0 dispatch layer for building MCP servers in Rust. Supports both stdio and HTTP transports.

Quick start

use llm_kernel::mcp::{McpServer, ToolDescription, JsonRpcDispatcher};

let mut server = McpServer::new("my-server", "1.0.0");

server.register_tool(ToolDescription {
    name: "greet".into(),
    description: "Say hello".into(),
    input_schema: serde_json::json!({
        "type": "object",
        "properties": {
            "name": { "type": "string" }
        }
    }),
});

server.set_handler("greet", |_params| {
    Ok(serde_json::json!({ "greeting": "Hello!" }))
});

// Route a JSON-RPC request through the stdio dispatcher.
let dispatcher = JsonRpcDispatcher::new(&server);
let response = dispatcher
    .dispatch(r#"{"jsonrpc":"2.0","id":1,"method":"tools/list"}"#)
    .unwrap();
assert!(response.contains("greet"));
