Pyodide服务器用于"模式上下文协议"(MCP)的实施. 这个服务器可以让大语言模型(LLMs)通过MCP接口执行Python代码.

□ 特性

• 使用 Pyodide 的 LLMS 的 Python 代码执行能力
• 符合MCP的服务器执行
• 支持Stdio和SSE两种运输方式
• 用类型脚本书写的有力执行
• 作为命令行工具可用

□ 安装

□ 使用量

作为服务器

作为命令行工具

以 stdio 模式启动( 默认) :

以 SSE 模式开始 :

SSE 模式

在SSE模式下运行时,服务器提供以下端点:

• SSE 连接: http://localhost:3020/sse
• 信件处理器:http://localhost:3020/messages

mcp-pyodide

A Pyodide server implementation for the Model Context Protocol (MCP). This server enables Large Language Models (LLMs) to execute Python code through the MCP interface.

Features

• Python code execution capability for LLMs using Pyodide
• MCP compliant server implementation
• Support for both stdio and SSE transport modes
• Robust implementation written in TypeScript
• Available as a command-line tool

Installation

npm install mcp-pyodide

Usage

As a Server

import { runServer } from "mcp-pyodide";

// Start the server
runServer().catch((error: unknown) => {
  console.error("Error starting server:", error);
  process.exit(1);
});

As a Command-line Tool

Start in stdio mode (default):

mcp-pyodide

Start in SSE mode:

mcp-pyodide --sse

SSE Mode

When running in SSE mode, the server provides the following endpoints:

• SSE Connection: http://localhost:3020/sse
• Message Handler: http://localhost:3020/messages

Example client connection:

const eventSource = new EventSource("http://localhost:3020/sse");
eventSource.onmessage = (event) => {
  console.log("Received:", JSON.parse(event.data));
};
