MMCP

A modular, minimalistic and macro-powered MCP (Model Context Protocol) framework for Rust.

Examples

mmcp = { version = "0.1", features = ["server-stdio"] }
uuid = { version = "1", features = ["v4"] }
tokio = { version = "1", features = ["full"] }

use mmcp::{
    server::{MCPServer, primitives::tool::Text, stdio_server_rpc},
    tool,
};
use uuid::Uuid;

/// Generate a UUID
#[tool]
fn generate_uuid() -> Text<Uuid> {
    Text(Uuid::new_v4())
}

/// Generate multiple UUIDs
#[tool]
fn generate_uuid_many(count: usize) -> Vec<Text<Uuid>> {
    (0..count).map(|_| generate_uuid()).collect()
}

#[tokio::main]
async fn main() {
    MCPServer::new("mmcp-uuid", env!("CARGO_PKG_VERSION"))
        .with_tools_from_inventory()
        .start(stdio_server_rpc())
        .await
        .unwrap();
}

Implementation Status

• STDIO server implementation
• Protocol definitions
• Tool macros
• RPC implementation
• HTTP transport with Axum
• Client implementation
• Authentication
• Logging
• Schemars 0.8 support
• Support more MCP functionalities
