MCP JavaScript Server
MCP サーバー - JavaScript SDK
これは、モデルコンテキストプロトコル用の非公式 JavaScript SDK です。
使用法
パッケージをプロジェクトにインポートします。
npm install mcp-js-serverサーバーのプロンプト、リソース、およびツールを定義するファイルを作成します。
プロンプト
// prompts.js
export const prompts = {
hello_world: {
description: 'A simple prompt that says hello.',
arguments: [],
messages: [{
role: 'assistant',
content: {
type: 'text',
text: 'Hello, world!'
}
}]
}
};リソース
// resources.js
export const resources = {
apiReference: {
uri: 'https://api.example.com/openapi.json',
mimeType: 'application/json'
}
};ツール
// tools.js
export const tools = {
simple_tool: {
description: 'A simple tool',
handler: async () => new Date().toLocaleString(),
schema: {
type: 'object',
properties: {},
required: []
}
},
complex_tool: {
description: 'A complex tool',
handler: async ({ param1, param2 }) => {
return `param1: ${param1}, param2: ${param2}`;
},
schema: {
type: 'object',
properties: {
param1: { type: 'string' },
param2: { type: 'string' }
},
required: ['param1', 'param2']
}
}
};サーバ
次に、次のコードを使用してサーバー インスタンスを作成します。
// server.js
import { MCP } from 'mcp-server';
import { tools } from './tools.js';
import { prompts } from './prompts.js';
import { resources } from './resources.js';
const infos = {
name: 'mcp-demo-server',
version: '0.1.0'
};
const server = new MCP(infos, prompts, resources, tools);デバッグ

The Mercado Pago MCP Server implements the Model Context Protocol to provide AI agents and LLMs with access to Mercado Pago's APIs and tools within compatible development environments. It acts as an intermediary that translates Mercado Pago resources into executable functions (tools) that AI applications can invoke to perform actions and automate flows. The server simplifies integration, enables using documentation to implement or improve code, and optimizes operations through natural language interactions without manual implementations.
