https://call4.me

call4me让你的AI代理为你打真实的电话。可以问Claude、ChatGPT、Cursor、Codex或你的 自有应用，可以预订座位、预约牙医、取消订阅或向企业提问， 它会打电话，等待等待，进入电话菜单，与接听的人通话，并反馈结果 还有文字记录。它也可以叫你加入通话。电话费用由预付费额度支付，起价为10美元。

用它

托管的MCP服务器是https://call4.me/mcp（可流式HTTP）。你的代理通过 浏览器使用Google或X。最简单的设置是粘贴 call4.me/mcp 的提示 进入你的代理人。手动添加：

光标：将其添加到~/.cursor/mcp.json，光标要求时登录。

在您自己的代码中，Vercel AI SDK 包为代理提供了相同的工具：

• 示例：真实呼叫及其提示。
• 博客：Claude Code 指南， AI SDK 以及更多。
• MCP注册表：io.github.skeptrunedev/call4me。

剩下的README是用来操作call4me本身或托管你自己的副本的。

通话的运作方式

• src/server/voice/prompt.ts：呼叫者被告知的内容。

call4me: MCP server for making phone calls

call4me is a remote MCP server for making phone calls. Point any MCP client at https://call4.me/mcp (streamable HTTP) and your agent can phone a business for you. One-line install for Claude Code:

claude mcp add --scope user --transport http call4me https://call4.me/mcp

https://call4.me

call4me lets your AI agent make real phone calls for you. Ask Claude, ChatGPT, Cursor, Codex or your own app to book a table, schedule a dentist appointment, cancel a subscription or ask a business a question, and it calls, waits on hold, gets through the phone menu, talks to the person who answers and reports back with the outcome and a transcript. It can also ring you to join the call. Calls are paid from prepaid credits, starting at $10.

Use it

In ChatGPT, install the call4me plugin and sign in to call4me. ChatGPT cannot install the plugin from a conversation; open the link yourself. The plugin supports tasks such as restaurant bookings, flight changes and business questions. It does not handle medical or dental appointments, health insurance, government ID numbers or account passwords.

For Claude, Codex and other MCP clients, the hosted server is https://call4.me/mcp (streamable HTTP). Your agent signs you in through the browser with Google or X. Paste the prompt from call4.me/mcp into your agent, or add it by hand:

claude code:     claude mcp add --scope user --transport http call4me https://call4.me/mcp   then /mcp, call4me, authenticate
codex:           codex mcp add call4me --url https://call4.me/mcp   then   codex mcp login call4me
claude desktop / claude.ai:  settings, connectors, add custom connector: https://call4.me/mcp
can't sign in?   create a key at https://call4.me/account and use https://call4.me/mcp/, or send "Authorization: Bearer " to /mcp

Cursor: add it to ~/.cursor/mcp.json and sign in when Cursor asks.

{
  "mcpServers": {
    "call4me": { "url": "https://call4.me/mcp" }
  }
}

In your own code, the Vercel AI SDK package gives an agent the same tools:

npm install call4me-ai-sdk ai zod @ai-sdk/openai

import { call4meTools } from 'call4me-ai-sdk';
// with CALL4ME_API_KEY set (from https://call4.me/account):
// generateText({ model, prompt: 'Call ... and ask ...', tools: call4meTools() })
