Common questions

Is CosVoice 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?

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 (1.0.0) reached the registry 2 months 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: Vexa, emailmd, MCP WhatsApp Cloud

CosVoice for Grok Bot, Claude, ChatGPT, and Cursor

An office for your AI Bot. CosVoice gives an AI assistant a real phone number (in your area code), a real email address, and a desk that keeps notes. The assistant can place calls for you, book restaurants by phone, answer the calls you miss, and read a written summary of every call. The voice on the line is Grok Voice, full duplex, and it always says it is an AI assistant when asked.

Website: https://cosvoice.com · Setup page written for the assistant: https://cosvoice.com/skill

Connect in one paste

https://cosvoice.com/mcp

Add that as a remote MCP server (Streamable HTTP). CosVoice uses OAuth 2.1 with PKCE and dynamic client registration, so a CosVoice page opens, you sign in, click Allow, and the assistant is connected. There is no API key to copy.

Client	How
Grok Bot / Grok	Settings → Plugins → add a custom MCP server by URL, or install this plugin
Claude (web, desktop, Code)	Add a custom connector / `claude mcp add --transport http cosvoice https://cosvoice.com/mcp`
ChatGPT	Settings → Connectors → add MCP server by URL (developer mode)
Cursor	Add to Cursor or paste the URL under Settings → MCP

Clients that only support a static header can use a key from Settings → Connect your agent as Authorization: Bearer cv_live_….

Then let the assistant set itself up

Send it: "Set up my CosVoice line in area code 949. Call it Lloyd."

It calls search_numbers, shows you options, and create_line. Payment comes first: if no plan is on file, create_line returns a checkout link for you to complete, then the number is issued.

What it can do

Tool	What it does
`get_account`, `search_numbers`, `create_line`	First-run setup: check the account, find numbers in an area code, create the line
`place_call`	Call a real number and hold a live conversation on your behalf (async; poll `get_call`)
`book_reservation`	Book a table by phone with a time window, fallbacks, seating, occasion, dietary notes
`get_call`, `list_calls`, `list_reservations`, `annotate_call`	Summaries, structured details, transcripts, outcomes
`send_text`, `list_messages`	Texts from and to the line (STOP respected)
`list_emails`, `get_email`, `forward_email`	The line's own inbox
`list_contacts`, `add_contact`, `remove_contact`	Owner, approved, VIP, blocked callers
`get_settings`, `update_settings`, `set_webhook`	Persona, voice, greeting, standing instructions, `call.completed` webhooks
`ack_instructions`	Texts you send the line from your own phone arrive as instructions on every tool result; acknowledge when handled
`list_history`, `recent_activity`, `list_integrations`	Unified history, catch-up since a timestamp, partner tools

What this repo contains

skills/cosvoice/SKILL.md — the skill (same text as https://cosvoice.com/skill)
.mcp.json — the hosted server entry (type: http, OAuth)
.grok-plugin/plugin.json and .claude-plugin/plugin.json — plugin manifests
server.json — the official MCP Registry entry (com.cosvoice/cosvoice)

No code runs on your machine. The plugin only points your client at the hosted server.

Rules the line follows

Never pays or reads out a card. Always says it is an AI assistant when asked. Uses its own number and email as the callback unless you say otherwise. Never claims a booking unless the call outcome says so. Respects STOP for texts.

Pricing

Starter $29/mo (60 min), Plus $69/mo (200 min), Pro $149/mo (600 min), overage $0.25/min. One number per paid month. Details: https://cosvoice.com/pricing
