This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Onesignal rest api account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Onesignal rest api with - [OpenAI Agents SDK](https://composio.dev/toolkits/onesignal_rest_api/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/onesignal_rest_api/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/onesignal_rest_api/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/onesignal_rest_api/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/onesignal_rest_api/framework/codex) - [OpenClaw](https://composio.dev/toolkits/onesignal_rest_api/framework/openclaw) - [Hermes](https://composio.dev/toolkits/onesignal_rest_api/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/onesignal_rest_api/framework/google-adk) - [LangChain](https://composio.dev/toolkits/onesignal_rest_api/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/onesignal_rest_api/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/onesignal_rest_api/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/onesignal_rest_api/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/onesignal_rest_api/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/onesignal_rest_api/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/onesignal_rest_api/framework/autogen) ## TL;DR ### How Atomic Agent connects to Onesignal rest api Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication. Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account. ## Connect Onesignal rest api to Atomic Agent ### Connect Onesignal rest api to Atomic Agent - Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key. - In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart. - Ask Atomic Agent to do something in Onesignal rest api. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Onesignal rest api account, then return to Atomic Agent to continue. ### Headless setup Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file. ```bash COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY ``` ## What is the Onesignal rest api MCP server, and what's possible with it? The Onesignal rest api MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your OneSignal account. It provides structured and secure access to your messaging platform, so your agent can perform actions like sending push notifications, managing devices, viewing app details, and segmenting audiences automatically on your behalf. - Automated push notifications and messaging: Instantly have your agent create and send targeted push notifications to your users, keeping them engaged and informed. - Device management and updates: Let your agent add, update, or remove registered devices (players) to keep your audience data fresh and accurate. - App insights and metadata retrieval: Effortlessly fetch and review detailed app information, notification history, and device lists for better operational visibility. - Audience segmentation and targeting: Enable your agent to view and utilize user segments, making it easy to target the right audience for every message. - Notification analytics and history: Have your agent retrieve past notifications, track delivery, and analyze engagement trends for continuous improvement. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `ONESIGNAL_REST_API_BEGIN_LIVE_ACTIVITY` | Begin Live Activity | Tool to start a Live Activity on OneSignal.

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying. ### Why are Composio tools unavailable after saving a key? Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk. ### Does Composio have a free plan? The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection. ## Complete Code None listed. ## Conclusion ### Use Onesignal rest api from Atomic Agent With your account connected, ask Atomic Agent to work with Onesignal rest api in natural language. You can connect more apps through the same Composio integration as you need them.

With a standalone Onesignal rest api MCP server, the agents and LLMs can only access a fixed set of Onesignal rest api tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Onesignal rest api and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Atomic Agent? Yes, you can. Atomic Agent fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Onesignal rest api tools. ### Can I manage the permissions and scopes for Onesignal rest api while using Tool Router? Yes, absolutely. You can configure which Onesignal rest api scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Onesignal rest api data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
