Frequently asked questions

What is the Wixzel Voice MCP server?

An MCP server with one tool per Wixzel Voice API endpoint, hosted at https://mcp.voice.wixzel.com/mcp.

How do I install it?

Pick your assistant above and follow the card. Most take one click or one command.

Which AI assistants are supported?

Claude, ChatGPT, Claude Code, Codex, Cursor, VS Code, GrokBot, Hermes, Gemini CLI, LM Studio, and any client that speaks Streamable HTTP.

Do I need an API key?

No. You sign in with your Wixzel Voice account. Only Cursor and LM Studio use a key, made for you in the console.

Can it place calls or spend credit on its own?

No. Tools that dial or spend are marked, so your assistant asks first. Keys for AI clients cannot top up or make more keys.

Is it secure?

Sign-in is OAuth with scopes you choose. Every connected client is listed in the console, and Disconnect revokes it at once.
