Integration

LoopMessage integration

LoopMessage sends and receives iMessage (with SMS, RCS and WhatsApp fallback) from dedicated sender names. Send texts, voice messages and reactions to a contact or group; show typing, edit or unsend; check delivery status; create and manage group chats; schedule bulk campaigns; generate opt-in links; read message and webhook history, the audience and subscription status; manage sender names, sender pools and organizations. Every send is a real message to a real person. LoopMessage bills by subscription plan, not per message (unlimited messages up to the plan's number of unique contacts), and answers 402 to a send the plan does not cover. Not exposed: ordering or cancelling sender names, identity documents, paid content, bulk data deletion, organization create, update and delete, and the Twilio-compatible API. Authentication is the organization API key (dashboard, API > Settings) sent raw in the Authorization header.

Connect LoopMessage How integrations work

Ask it in chat

Say what should happen.
The workflow builds itself.

When this happens, do that in LoopMessage.Built from the 30 LoopMessage tools below, on the connection you add once.

What you can do with LoopMessage

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Most endpoints run on the free plan. A few, mainly the ones that publish on your behalf, need a paid plan.

Message, 8 operations

edit_messageEdit messagePOSTReplaces the text of an outbound message sent within the last 15 minutes (iMessage). Inbound messages and the first message of a conversation cannot be edited; SMS and RCS do not support editing.
get_message_statusGet message statusGETReturns the delivery status of a message you sent (processing, delivered, failed or unknown), with its contact, text, error code when it failed, and last update time.
list_contact_messagesList contact messagesGETLists the message history with one contact, a page at a time, filterable by date range, direction and type, plus the contact's subscription status. Holds message text.
send_messageSend messagePOSTSends a real iMessage (or SMS, RCS or WhatsApp) text to one contact or to a group. Pass contact or group, and text. The 200 answer only means queued; check get_message_status.
send_reactionSend reactionPOSTPuts a reaction on a contact's message: an emoji, or an iMessage tapback (love, like, dislike, laugh, emphasize, question). Prefix the value with - to remove it, for example -like.

get_groupGet groupGETReturns a group chat's name, participants, channel, sender name and creation date.
remove_group_participantRemove group participantDELETERemoves a participant from a group chat. Processed asynchronously; the answer confirms the request was accepted.
update_groupUpdate groupPATCHRenames a group chat or changes its photo; send one change per call. An empty photo_url removes the photo. Processed asynchronously.

Sender pool, 5 operations

create_sender_poolCreate sender poolPOSTCreates a pool of sender names from their IDs (list_senders). Returns the new pool with its id.

Use LoopMessage from Claude Code, Cursor or Codex

Connect LoopMessage in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its LoopMessage operations become tools the client can call, next to every other integration you connected.

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

Codex (~/.codex/config.toml)

[mcp_servers.livecontext]
url = "https://livecontext.ai/mcp"

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"

Cursor, Claude Desktop and other JSON configs

{
  "mcpServers": {
    "livecontext": {
      "type": "http",
      "url": "https://livecontext.ai/mcp",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
      }
    }
  }
}

Set up the MCP server step by step

How to connect LoopMessage

Create your workspace
Sign up free. Nothing to install.
Connect LoopMessage once
Add your LoopMessage connection in Settings. Every tool from this integration reuses it, and secrets are encrypted at rest and visible only to you.
Describe the job in chat
The workflow builds itself in front of you and picks the endpoints it needs. Drag the steps yourself on the canvas whenever you would rather be explicit.
