概览

AI 生成的概览

托管式 MCP 服务器，让助手拨打真实电话、用 12 种语言进行语音对话，并回报通话内容。

可以做什么
  • 拨打号码并围绕目标自主完成对话，返回通话记录、收集到的答复和摘要
  • 拨打电话后逐轮控制：说话、聆听对方回复、挂断
  • 查询预付积分余额，并用已保存的支付方式充值积分
  • 可用于预约或改约、向商家提问、确认订单、筛选来电者、开展问卷调查
适用场景
当助手需要通过电话而非文字办事时使用：在支持的国家预约或更改预约、向商家询问、确认订单、筛选来电者或进行简短调查。
运行要求
远程 Streamable HTTP 端点 mcp.alterphone.app/mcp；需 OAuth 2.1（PKCE 与动态客户端注册），首次使用时用 Google 或 Apple 登录。仅支持本地 stdio 的客户端需使用 npx 桥接包，并要求 Node.js 18 或更高版本。通话需要预付积分。
安装前请注意
通话会产生费用：预付积分按目的地费率以开始的每分钟计费，purchase_credits 工具可用已保存的支付方式在每日上限内充值。助手会拨打真实电话并代表用户发言，应事先审阅通话目标与开场白；通话计划会接受欺诈、骚扰和冒充等违规用途筛查。通话记录保留 24 小时。仅允许拨打所列国家的呼出电话，每个账户同时只能有一通电话。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/app.alterphone%2Fphone-calls/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。

README

AlterPhone MCP

Let your AI assistant make real phone calls.

AlterPhone MCP is a hosted Model Context Protocol server. Connect it to Claude, ChatGPT, Cursor, Claude Code or any other MCP client, and the assistant can dial a real phone number, hold a spoken conversation in one of 12 languages, and report back what was said: book or reschedule appointments, ask a business a question, negotiate, confirm an order, screen a caller, run a survey.

  • Server URL: https://mcp.alterphone.app/mcp (Streamable HTTP)
  • Registry name: app.alterphone/phone-calls in the official MCP Registry
  • Auth: OAuth 2.1 with PKCE and dynamic client registration. Sign in with Google or Apple on first use.
  • Billing: prepaid credits, 100 credits per US dollar, per started minute at the destination rate (about 8 credits per minute to the US). Same account and balance as the AlterPhone app.

Full details, tools and supported countries: https://alterphone.app/mcp.html

Quick start

Claude (claude.ai and Claude Desktop)

Settings → Connectors → Add custom connector → enter https://mcp.alterphone.app/mcp → complete the sign-in.

ChatGPT

Settings → Connectors → create a connector with the server URL https://mcp.alterphone.app/mcp → complete the sign-in. Custom MCP connectors require developer mode on your plan.

Claude Code

bash
claude mcp add --transport http -s user alterphone https://mcp.alterphone.app/mcp

Cursor, Windsurf and other clients with an MCP config file

json
{  "mcpServers": {    "alterphone": {      "url": "https://mcp.alterphone.app/mcp"    }  }}

Clients that only run local (stdio) servers

This package is a thin bridge for that case. It delegates to mcp-remote, which performs the browser sign-in, caches the tokens locally and forwards every message to the hosted server:

json
{  "mcpServers": {    "alterphone": {      "command": "npx",      "args": ["-y", "alterphone-mcp"]    }  }}

Requires Node.js 18 or newer. Set ALTERPHONE_MCP_URL to point the bridge at a different server.
