Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools. With Composio Connect, Cowork can securely access apps like Onesignal rest api through MCP without you sharing account credentials directly with the agent. ## 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 Claude Cowork? Yes, you can. Claude Cowork 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)
