XMCP Application

This project was created with create-xmcp-app.

Getting Started

First, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev

This will start the MCP server with both SSE and STDIO transport methods.

Project Structure

This project uses the structured approach where tools are automatically discovered from the src/tools directory. Each tool is defined in its own file with the following structure:

import { z } from "zod";
import { type InferSchema } from "xmcp";

// Define the schema for tool parameters
export const schema = {
  a: z.number().describe("First number to add"),
  b: z.number().describe("Second number to add"),
};

// Define tool metadata
export const metadata = {
  name: "add",
  description: "Add two numbers together",
  annotations: {
    title: "Add Two Numbers",
    readOnlyHint: true,
    destructiveHint: false,
    idempotentHint: true,
  },
};

// Tool implementation
export default async function add({ a, b }: InferSchema<typeof schema>) {
  return {
    content: [{ type: "text", text: String(a + b) }],
  };
}

Adding New Tools

To add a new tool:

1. Create a new .ts file in the src/tools directory
2. Export a schema object defining the tool parameters using Zod
3. Export a metadata object with tool information
4. Export a default function that implements the tool logic

Building for Production
