Integrations

  • Provides a JavaScript SDK for implementing the Model Context Protocol, allowing developers to build MCP servers using JavaScript

MCP Server - JavaScript SDK

This is an unofficial JavaScript SDK for Model Context Protocol.

Usage

Import the package to your project:

npm install mcp-js-server

Create files to define the server's prompts, resources, and tools.

Prompts

// prompts.js export const prompts = { hello_world: { description: 'A simple prompt that says hello.', arguments: [], messages: [{ role: 'assistant', content: { type: 'text', text: 'Hello, world!' } }] } };

Resources

// resources.js export const resources = { apiReference: { uri: 'https://api.example.com/openapi.json', mimeType: 'application/json' } };

Tools

// 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'] } } };

Server

Then create a server instance with the following code:

// 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);

Debugging

You can find logs of the server in your user system logs directory:

Linux: ~/.local/share/logs macOS: ~/Library/Logs Windows: %USERPROFILE%\AppData\Local\Logs

remote-capable server

The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.
