PulseEngine MCP Macros

Procedural macros for the PulseEngine MCP Framework that dramatically simplify server and tool development.

Overview

This crate provides macros that reduce boilerplate code and enable a more developer-friendly experience while maintaining the enterprise-grade capabilities of PulseEngine MCP.

Macros

#[mcp_tool]

Automatically generates MCP tool definitions from Rust functions:

use pulseengine_mcp_macros::mcp_tool;

#[mcp_tool(description = "Say hello to someone")]
async fn say_hello(name: String, greeting: Option<String>) -> String {
    format!("{}, {}!", greeting.unwrap_or("Hello"), name)
}

#[mcp_backend]

Auto-implements the McpBackend trait:

use pulseengine_mcp_macros::mcp_backend;

#[mcp_backend(name = "Hello World Server")]
struct HelloWorldBackend;

#[mcp_server]

Complete server generation from a simple struct:

use pulseengine_mcp_macros::mcp_server;

#[mcp_server(name = "My Server")]
struct MyServer;

Features

• Zero Boilerplate: Focus on business logic, not protocol details
• Type Safety: Compile-time validation of tool definitions
• Auto Schema Generation: JSON schemas derived from Rust types
• Doc Comments: Function documentation becomes tool descriptions
• Progressive Complexity: Start simple, add enterprise features as needed

Usage

Add this to your Cargo.toml:

[dependencies]
pulseengine-mcp-macros = "0.5"
