Overview

Description from the maker (original English)

A phone for your AI: CG rings or texts you when a job is done, and calls businesses for you.

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.

Install

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

Before you install

  • Basic checks: 2 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

You need

Which app do you use?

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

Or copy the settings yourself

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

{
  "mcpServers": {
    "cg": {
      "url": "https://connect.callcg.com/mcp"
    }
  }
}

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": {
    "cg": {
      "type": "http",
      "url": "https://connect.callcg.com/mcp"
    }
  }
}

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.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker
SettingsConnectors1+ Create2https://…3
https://connect.callcg.com/mcp

Menu names can differ slightly by plan and over time.

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

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

What it can do

The server asks you to sign in before it lists its tools.

Compared with others in Otheri

  • More stars than 0% of the other 32558 servers in this category
  • Published to the registry more recently than 93% of the other 32558 servers in this category
  • Basic checks equal to or better than 37% of the other 32558 servers in this category

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is CG safe?

It passed 2 of 3 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.0.0) reached the registry 2 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, FactLot

CG for Claude Code

A phone for your AI. Install this, give Claude your mobile number, read it the code that arrives, and from then on Claude can ring or text you the moment a long job is done, and have CG phone people and businesses for you.

claude plugin marketplace add 711webservices/cg-plugin

claude plugin install cg@cg-plugin

Then, in Claude Code: "set up CG".

No plugin? One line does the same:

claude mcp add --transport http --scope user cg-start https://connect.callcg.com/mcp/start

No terminal at all? The Claude app, ChatGPT and Grok take CG with one paste: see callcg.com/start.

What happens

  1. Claude asks for your mobile number with the country code (US or UK mobile with a SIM).
  2. CG texts you a 6-digit code (WhatsApp in the UK). You read it to Claude.
  3. Claude gets your private CG link and adds it: claude mcp add --transport http --scope user cg . Restart Claude Code.

That is the whole sign-up. Your number is your account; there is no password.

Then say things like

  • "Run the full test suite and call me when it's done."
  • "Deploy, then text me the summary." / "WhatsApp me when the build is green."
  • "Call the dentist and move my Thursday appointment to after 2."
  • "Find three plumbers near me and get quotes for the kitchen leak."

It is two-way. Write to CG from your phone ("Claude: the build looks wrong, check the logs") and Claude picks it up with my_messages, or waits for your answer with wait_for_messages.

When the job finishes, Claude calls call_me (CG rings and speaks one sentence, and texts the details) or text_me (by SMS or WhatsApp, as you asked). For calls to other people, CG dials, presses menu keys, waits on hold, talks to whoever answers, and reports back.

Rules CG keeps

  • CG never claims a call or text happened unless it did.
  • CG phones the people in your contacts and listed businesses. A stranger's number is refused until you say who it is.
  • Up to 10 calls a day to personal numbers. Businesses and your own phone are not counted.
  • Every call opens with "this is CG, 's AI assistant". Anyone can say "stop calling me" and CG will not call them again for you.
  • Your link is the key to your account. Keep it out of repos. Text CG "revoke my AI link" to cut it.

Price

A 7-day free trial on CG's shared number, no card: 10 minutes of calls with CG, 10 texts and 2 questions or document reviews by the AI council, one trial per mobile number. Calls CG makes for you come with the CG plan: $9 a month with your own number, with your first payment back in full if you ask within 30 days; ask CG to start it, or see callcg.com. US and UK only for now.

Other agents and apps

Cursor, Codex, Gemini CLI, VS Code, Windsurf, ChatGPT and Claude.ai take the same private link. Any MCP client can run the two set-up tools at https://connect.callcg.com/mcp/start; setup snippets for each are at callcg.com/agents.

For your project's CLAUDE.md

## Reaching me

CG is connected (MCP server cg). When I ask to be told when a job is done: finish, then call call_me with a one-sentence say (or text_me, via sms/whatsapp when I named one). Never report a call or text as made unless the tool result says so.

What is in this repo

  • .mcp.json: the set-up server (cg-start, two tools, no key).
  • skills/cg/SKILL.md: how Claude sets you up and uses the cg tools honestly.
  • .claude-plugin/: the plugin and marketplace manifests.

The CG service itself is not in this repo. Privacy and terms: callcg.com/privacy, callcg.com/terms.
