MCP support
CG exposes tools to MCP clients for setup, calling, texting, and retrieving or waiting for messages. Clients connect to the hosted service using its MCP endpoint or a private link.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

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

## 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.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
