Send Your First Message

You can start sending messages in multiple ways, depending on how you want to integrate:

• MCP Server

Connect the MCP (Model Context Protocol) server to let tools interact with Siren through function calls for messaging and other actions.
Go to MCP to see the integration guide

• AI Agent Toolkit

The AI Agent Toolkit provides a set of predefined tools that let your agent perform different tasks within Siren. To learn more about the available tools and how to integrate them, go to the AI Agent Toolkit Reference.

• SDK

Use the Siren Python SDK to call built-in functions for sending messages and triggering workflows directly from your backend. Go to SDK Docs to see the integration guide

• API

Use Siren’s flexible, lightweight APIs to send messages without creating a full workflow. You can trigger one-off notifications using APIs. View API Reference to see how to send messages using APIs.
