MCP 服务器 - JavaScript SDK
这是模型上下文协议的非官方 JavaScript SDK。
用法
将包导入到您的项目中：
npm install mcp-js-server创建文件来定义服务器的提示、资源和工具。
提示
// prompts.js
export const prompts = {
hello_world: {
description: 'A simple prompt that says hello.',
arguments: [],
messages: [{
role: 'assistant',
content: {
type: 'text',
text: 'Hello, world!'
}
}]
}
};资源
// resources.js
export const resources = {
apiReference: {
uri: 'https://api.example.com/openapi.json',
mimeType: 'application/json'
}
};工具
// 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']
}
}
};服务器
然后使用以下代码创建服务器实例：
// 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);调试
您可以在用户系统日志目录中找到服务器的日志：
Linux: ~/.local/share/logs
macOS: ~/Library/Logs
Windows: %USERPROFILE%\AppData\Local\LogsThis server cannot be installed

Looking for Admin?
Admins can modify the Dockerfile, update the server description, and track usage metrics. If you are the server author, to access the admin panel.
