mcp.zigModel Context Protocol for Zig

🎯 Why mcp.zig? ​

The Model Context Protocol (MCP) is an open standard by Anthropic for connecting AI applications to external systems. While MCP has official SDKs for TypeScript, Python, and other languages, Zig currently lacks proper MCP support.

mcp.zig fills this gap by providing a native, high-performance MCP implementation for Zig developers.

Quick Start ​

Installation ​

Run the following command to add mcp.zig to your project:

zig fetch --save https://github.com/muhammad-fiaz/mcp.zig/archive/refs/tags/v0.0.1.tar.gz

Create a Simple Server ​

const std = @import("std");
const mcp = @import("mcp");

pub fn main() void {
    run() catch |err| {
        mcp.reportError(err);
    };
}

fn run() !void {
    var gpa = std.heap.GeneralPurposeAllocator(.{}){};
    defer _ = gpa.deinit();
    const allocator = gpa.allocator();

    var server = mcp.Server.init(.{
        .name = "my-server",
        .version = "1.0.0",
        .allocator = allocator,
    });
    defer server.deinit();

    // Enable capabilities
    server.enableTools();

    // Register a tool
    try server.addTool(.{
        .name = "greet",
        .description = "Greet a user",
        .handler = greetHandler,
    });

    // Run with STDIO transport
    try server.run(.stdio);
}

Why Choose mcp.zig? ​

What is MCP? ​

The Model Context Protocol (MCP) is an open standard that enables:

• 🔧 Tools - Functions that AI can call to perform actions
• 📁 Resources - Data that AI can read and reference
• 💬 Prompts - Reusable templates for AI interactions
• 🔌 Transports - Communication channels (STDIO, HTTP)
