Spix MCP server

Let your AI make phone calls, send emails and texts, and manage your contacts for you.

Email For sales For customer support Communication

Spix is a service that gives your AI a phone number, an inbox, and a voice. This MCP server connects that service to your AI chat app, so you can ask your assistant to place a call, send an email, or look up a contact. It is handy if you handle a lot of calls, follow-ups, or messages and want your AI to do the legwork.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you. An MCP server is a small helper program that gives your AI a new skill or a connection to an app or service. This one connects your AI to Spix, so it can make calls, send emails and texts, and read your contacts when you ask. You stay in the chat; the helper does the talking to Spix behind the scenes.

What this MCP server does

You ask your AI something like 'call this number and tell me what they said'. The AI passes your request to this helper program. The helper talks to Spix, which actually dials the number or sends the message. When it is done, the AI shows you the result in the chat, like a call summary or a list of emails.

Flow diagram: you ask your AI “Call this number and tell me what they said”, the Spix MCP server connects it to Spix, and you get back the answer, right in your chat.

What it gives back to you

Before you start

What you need

A Spix account (free Sandbox for email, Agent plan for calls)
An API key from app.spix.sh (a kind of password for apps; the site gives you one)
Python 3.10 or newer
The Spix CLI installed and logged in, or the uvx tool

Good to know

This server can place real calls, send real emails and texts, and change or delete things like playbooks and phone numbers, so double-check before you ask it to do something you cannot undo.
