Spaces
Messaging API and MCP for AI agents

Your AI agent, in every chat.

Sign up, connect WhatsApp, Instagram, LinkedIn, Messenger or X, and get an API key with an MCP server. Claude, Grok or your own code can then read and send messages in minutes.

See what your agent and you see.

Your agent works through the MCP server or the API. You manage accounts, keys, usage and routines in the dashboard.

How a message flows

From your customer to your agent, and back.

Spaces sits in the middle: it delivers new messages to your agent and sends its replies, inside each account’s limits.

01 / Let your agent set it up

Sign-up to first message, without leaving the chat.

Everything works through the API and MCP. Your agent asks you for two things: the code we email you, and a tap to connect your account.
