Claw Messenger is a messaging API that gives AI agents a dedicated US phone number to send and receive iMessage, RCS, and SMS without requiring a Mac, built for developers running agents on Linux, VPS, or Docker.
What is Claw Messenger?
Claw Messenger is a cloud-based API service that lets AI agents exchange native iMessage, RCS, and SMS messages using a dedicated US phone number. It accepts HTTP requests containing a phone number and text, and delivers replies back to your agent via WebSocket, webhook, or backend. The platform runs entirely server-side — no Mac, Apple device, or BlueBubbles relay is needed on your side. The service is built and maintained by Claw Messenger (no parent company stated).
Key Features
- No Mac required – Agents run on any platform (Linux, Docker, Windows, cloud). Claw Messenger handles the iMessage relay. See how it compares.
- Dedicated phone number – Each subscription includes a dedicated agent line. Only phone numbers you register can initiate conversations with your agent. Learn about agent phone numbers.
- iMessage + RCS + SMS – One API sends across three protocols with automatic fallback depending on the recipient’s device and carrier.
- Tapbacks, typing indicators, read receipts – Full native iMessage experience: reactions, typing bubbles, and read receipts are supported.
- Group messaging – Agents can participate in group conversations with multiple people at once.
- HMAC-signed webhooks – Incoming replies are delivered as signed webhooks for secure verification.
- Integrates with any agent framework – REST API and WebSocket work with LangChain, n8n, CrewAI, and custom agents. Native plugins for OpenClaw (5-min setup) and Hermes Agent (no Mac, package-based).
Who is it for?
- AI agent developers who need to give their agent real-time iMessage capabilities on Linux or cloud infrastructure.
- Technical teams evaluating multi-agent messaging – builders from OpenAI, Microsoft, Persist Ventures, and Moveris have started testing Claw Messenger (company names reflect individual affiliations, not endorsements).
- Agencies and resellers needing multi-tenant or subaccount routing – a dedicated agency tier with managed routing is available. See agency tier.
What can you do with Claw Messenger?
- Proof a single agent thread: Start a 7-day free trial, send one controlled iMessage to a phone you can answer, reply from that phone, and confirm the reply reaches your agent’s webhook or backend. Send your first agent message | Read the working-thread quickstart.
- Run a production agent that texts like a human: Use tapbacks, typing indicators, and read receipts to make agent replies feel native in iMessage group chats or one-on-one conversations.
- Integrate into existing automation: Add a REST API call to LangChain tools, n8n HTTP Request nodes, or any custom agent framework that can make HTTP requests.
How does it work?
- Start a trial – Pick a plan (all include 7-day free trial) and keep the first run small: one working thread.
- Create an API key – Copy the key into your agent, script, or backend. Keep it out of logs and public prompts.
- Send a test message – Use a single
curl POST to send a plain text iMessage to a phone you control.
- Reply and confirm – Reply from that phone and verify the response arrives at your agent, webhook, or backend.
