And MCP makes the experience even better. With Onesignal rest api MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## 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) - [OpenClaw](https://composio.dev/toolkits/onesignal_rest_api/framework/openclaw) - [Hermes](https://composio.dev/toolkits/onesignal_rest_api/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/onesignal_rest_api/framework/cli) - [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) ## TL;DR ### Why use Composio? Apart from a managed and hosted MCP server, you will get: - CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling. - Large tool responses: Handle them to minimise context rot. - Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need. ## Connect Onesignal rest api to Codex ### How to install Onesignal rest api MCP in Codex ### Run the setup command Run this command in your terminal to add the Composio MCP server to Codex. ```bash codex mcp add composio --url https://connect.composio.dev/mcp ``` ## 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.

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 Codex? Yes, you can. Codex 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)
