PyPI version Python Version License: MIT

一个简单的MCP (Model Context Protocol) 服务器,提供echo功能:输入什么就返回什么。

项目信息

  • 作者: Bach Studio
  • GitHub: https://github.com/BACH-AI-Tools/mcp-echo
  • PyPI: https://pypi.org/project/mcp-echo/

功能特性

  • echo工具: 接收一个消息参数,并原样返回该消息
  • 简单易用,适合测试MCP连接
  • 支持命令行直接运行

安装

从 PyPI 安装(推荐)

pip install mcp-echo

从源码安装

git clone https://github.com/BACH-AI-Tools/mcp-echo.git
cd mcp-echo
pip install -e .

使用方法

命令行运行

安装后,可以直接使用命令行启动服务器:

mcp-echo

在 Cherry Studio 中使用

  1. 打开 Cherry Studio
  2. 进入设置 -> MCP服务器配置
  3. 添加新的MCP服务器配置:
{
  "mcpServers": {
    "echo": {
      "command": "mcp-echo"
    }
  }
}

或者使用完整Python路径(如果命令行不可用):

{
  "mcpServers": {
    "echo": {
      "command": "python",
      "args": [
        "-m",
        "mcp_echo.server"
      ]
    }
  }
}

在 Claude Desktop 中使用

编辑配置文件:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json

添加配置:

{
  "mcpServers": {
    "echo": {
      "command": "mcp-echo"
    }
  }
}

使用示例

在支持MCP的AI助手中,你可以这样使用echo工具:

  • "请使用echo工具返回'Hello World'"
  • "用echo工具测试一下:这是一条测试消息"

工具说明

echo

  • 描述: 输入什么就返回什么
  • 参数:
