## Introduction

Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,500+ apps through Composio, including Onesignal user auth.
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 user auth account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions.

## TL;DR

### How Atomic Agent connects to Onesignal user auth
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 user auth to Atomic Agent

### Connect Onesignal user auth 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 user auth. It searches Composio for the right tool.
- On first use, open the sign-in link returned in the chat. Connect your Onesignal user auth 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 user auth MCP server, and what's possible with it?

The Onesignal user auth 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 user auth account. It provides structured and secure access to your Onesignal workspace, so your agent can perform actions like managing device tags, updating player records, inspecting app segments, and retrieving device information on your behalf.
- Device tag management: Assign or update custom tags on OneSignal devices to enable powerful audience segmentation and personalized messaging.
- Edit device/player attributes: Update details or attributes for any registered device (player) in your OneSignal app using your agent.
- Segment inspection and listing: Retrieve details for specific segments or list all segments in your app to optimize and analyze your audience targeting strategies.
- Device and app information retrieval: Look up detailed information about individual devices or your entire OneSignal app configuration as needed.
- View device tags and metadata: Fetch all key/value tags assigned to a particular player for deeper insight into user attributes and behaviors.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `ONESIGNAL_USER_AUTH_CREATE_USER` | Create or Update OneSignal User | Tool to create a new user or modify the subscriptions associated with an existing user. Use when you need to register a user with OneSignal or update their subscriptions. |
| `ONESIGNAL_USER_AUTH_DELETE_ALIAS` | Delete User Alias | Tool to remove an alias from a OneSignal user. Use when you need to delete a specific alias identifier from a user while preserving other aliases. The user is identified by one alias (alias_label/alias_id) and a different alias (alias_label_to_delete) is removed. |
| `ONESIGNAL_USER_AUTH_EDIT_DEVICE` | Edit OneSignal Device | Tool to update an existing OneSignal device (player) record. Use when you have the player_id and need to modify device attributes. |
| `ONESIGNAL_USER_AUTH_ONESIGNAL_VIEW_SEGMENT` | View OneSignal Segment | Tool to retrieve the subscriber count for a specific OneSignal segment. Use when you need to know how many subscribers are in a segment. |
| `ONESIGNAL_USER_AUTH_UPDATE_SUBSCRIPTION_BY_TOKEN` | Update Subscription By Token | Tool to update properties on an existing subscription using its token. Use when you need to enable or disable subscription status when managing outside of the OneSignal SDK. |
| `ONESIGNAL_USER_AUTH_VIEW_APP` | View App | Tool to retrieve details for a specific OneSignal app. Use after authenticating to inspect app settings. |
| `ONESIGNAL_USER_AUTH_VIEW_BROADCASTS` | View Broadcasts | Tool to view inbox broadcasts for a OneSignal app. Returns broadcasts in descending order of creation. Use when retrieving in-app messages or inbox content for an app. |
| `ONESIGNAL_USER_AUTH_VIEW_DEVICE` | View OneSignal Device | Tool to retrieve details for a specific device/player. Use when you have a player_id and optional app_id. |
| `ONESIGNAL_USER_AUTH_VIEW_OUTCOMES` | View Outcomes | Tool to view all outcomes associated with a OneSignal app. Use to retrieve outcome metrics filtered by time range, platforms, and attribution type. |
| `ONESIGNAL_USER_AUTH_VIEW_SEGMENTS` | View Segments | Tool to list all segments for an app. Use after obtaining the app_id to retrieve a paginated list of segments. |
| `ONESIGNAL_USER_AUTH_VIEW_USER` | View OneSignal User | Tool to retrieve user details by alias label and ID. Use when you need to fetch user data including tags, subscriptions, and identity information. |
| `ONESIGNAL_USER_AUTH_VIEW_USER_UNREAD_MESSAGE_COUNT` | View User Unread Message Count | Tool to retrieve the unread message count for a specific user. Use when you need to check how many unread inbox messages a user has. |

## Troubleshooting

### Why is my API key rejected?

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 user auth from Atomic Agent
With your account connected, ask Atomic Agent to work with Onesignal user auth in natural language. You can connect more apps through the same Composio integration as you need them.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Onesignal user auth MCP?

With a standalone Onesignal user auth MCP server, the agents and LLMs can only access a fixed set of Onesignal user auth tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Onesignal user auth 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 user auth tools.

### Can I manage the permissions and scopes for Onesignal user auth while using Tool Router?

Yes, absolutely. You can configure which Onesignal user auth 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 user auth data and credentials are handled as safely as possible.
