给朋友打电话MCP

一个MCP服务器，使Claude Code实例能够实时通信。一个实例进入“监听模式”，而另一个实例则以特定意图发起联系。

安装

cd ~/.claude/mcps/phone-a-friend
pip install -e .

用法

步骤1：启动Hub

paf-hub

步骤2：配置Claude代码

添加到 ~/.claude/settings.json:

{
  "mcpServers": {
    "phone-a-friend": {
      "command": "python",
      "args": ["-m", "phone_a_friend.server"],
      "cwd": "/Users/YOUR_USERNAME/.claude/mcps/phone-a-friend/src"
    }
  }
}

第三步：使用它

选项卡1（侦听器）：

"Listen for questions. You're the auth expert."

→ paf(action="listen", session_name="auth-expert", description="Expert on auth") → 街区等待。..

选项卡2（呼叫者）：

"Ask the auth expert about token refresh."

→ paf(action="list_sessions") → 看到“身份验证专家” → paf(action="connect", target_session="auth-expert", intent="Token refresh", my_name="feature-dev") → paf(action="send", target_session="auth-expert", message="How handle expired tokens?", my_name="feature-dev") → paf(action="wait_response", my_name="feature-dev") → 答案块

选项卡1接收并响应： → 听众用问题解封 → paf(action="respond", session_name="auth-expert", message="Use sliding window...") → paf(action="listen", ...) → 回到等待
