Overview

Description from the maker (original English)

A business phone system for AI agents: send texts, place calls, read transcripts, buy numbers.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Chat & email
  • You need to fill in: HANDSET_API_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: HANDSET_API_KEY, HANDSET_ALLOW_LIVE

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "handset": {
      "command": "npx",
      "args": [
        "-y",
        "@handset/mcp"
      ],
      "env": {
        "HANDSET_API_KEY": "your-value",
        "HANDSET_ALLOW_LIVE": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add handset --env HANDSET_API_KEY=your-value --env HANDSET_ALLOW_LIVE=your-value -- npx -y @handset/mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "handset": {
      "command": "npx",
      "args": [
        "-y",
        "@handset/mcp"
      ],
      "env": {
        "HANDSET_API_KEY": "your-value",
        "HANDSET_ALLOW_LIVE": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "handset": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@handset/mcp"
      ],
      "env": {
        "HANDSET_API_KEY": "your-value",
        "HANDSET_ALLOW_LIVE": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • HANDSET_API_KEY secret required env
    Handset API key. Use a test-mode key (hs_test_…) — simulated carrier, free. Live keys are refused unless HANDSET_ALLOW_LIVE=1.
  • HANDSET_ALLOW_LIVE env
    Set to 1 to permit a live-mode key (the agent can then text and call real people at real cost).

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Common questions

Is Handset safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: HANDSET_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

In the same category: Vexa, emailmd, MCP WhatsApp Cloud

Handset UI

Texting inside your product, in an afternoon.

Open-source React components for embedded messaging, built on the Handset API. Distributed the shadcn way: the CLI copies the source into your repo, styled with your Tailwind tokens, yours to change.

# 1. Point the shadcn CLI at the Handset registry

npx shadcn@latest registry add @handset=https://ui.handset.dev/r/{name}.json

2. Install a complete texting surface + the server proxy route

npx shadcn@latest add @handset/messaging @handset/next-routes

Set HANDSET_API_KEY in your env, wire resolveTenantId() in the generated route to your session, and render it:

import { HandsetProvider } from "@handset/react";

import { Messaging } from "@/components/handset/messaging";

export default function MessagesPage() { return (

); }

What's in the registry

ItemWhat it is
@handset/messagingTwo-pane texting surface — inbox + thread, responsive to mobile
@handset/inboxConversation list: previews, relative times, STOP badges, infinite scroll
@handset/threadMessage history: delivery states, opt-out handling, wired composer
@handset/composerDraft box with live SMS segment counting and unicode detection
@handset/next-routesNext.js proxy route — your API key never reaches the browser

Architecture

Two layers, like shadcn-on-Radix:

  • [`@handset/react`](packages/react) (npm, versioned) — headless hooks: useConversations, useThread, useComposer, plus segment math and a tiny client. Logic we maintain; bring your own UI if you prefer.
  • The registry (apps/www/registry) — the visual components, copied into your project as source.

Components never hold API keys. They call proxy routes in your backend (added by @handset/next-routes); your server holds the Handset key and your existing session auth decides which tenant each signed-in user sees. The Handset API handles the rest — numbers, delivery, threading, 10DLC compliance, STOP/HELP.

Development

pnpm install

pnpm --filter @handset/react build # hooks package pnpm dev # docs site + live demo at localhost:3000 pnpm registry:build # compile registry.json → public/r/*.json

The docs site serves a mock Handset API (apps/www/app/api/handset) so the demo works with zero setup.

Requirements

  • React 18+ (components target React 19 / Tailwind v4 / shadcn CLI ≥ 3)
  • A Handset account for real traffic — the demo runs on mock data without one

Roadmap

See ROADMAP.md — shipped components, what's next (call summaries, MMS attachments, more framework proxies), and non-goals. Issues with real use cases move items up the list.
