rmcp-macros

Procedural macros for the RMCP SDK. Most users should depend on rmcp with the macros feature (enabled by default) rather than using this crate directly.

For getting started and full MCP feature documentation, see the main README.

Available Macros

Macro	Description
#[tool]	Mark a function as an MCP tool handler
#[tool_router]	Generate a tool router from an impl block
#[tool_handler]	Generate call_tool and list_tools handler methods
#[prompt]	Mark a function as an MCP prompt handler
#[prompt_router]	Generate a prompt router from an impl block
#[prompt_handler]	Generate get_prompt and list_prompts handler methods
#[task_handler]	Wire up the task lifecycle on top of an OperationProcessor

Quick Example

use rmcp::{tool, tool_router, tool_handler, ServerHandler, model::*};

#[derive(Clone)]
struct MyServer {
    tool_router: rmcp::handler::server::tool::ToolRouter<Self>,
}

#[tool_router]
impl MyServer {
    #[tool(description = "Say hello")]
    async fn hello(&self) -> String {
        "Hello, world!".into()
    }
}

#[tool_handler]
impl ServerHandler for MyServer {
    fn get_info(&self) -> ServerInfo {
        ServerInfo::default()
    }
}
