Frequently asked questions
Can I target specific users instead of sending to everyone?
Yes! Use the create_notification tool and provide a list of include_player_ids. This ensures the notification is only delivered to the specific devices you've identified.
How can I check if a scheduled notification was actually sent?
You can use the get_notification tool with the Notification ID. It will return real-time delivery metrics, including the number of successful deliveries and current status.
Is it possible to manage multiple OneSignal apps?
Yes. While the core operations use the primary App ID provided in credentials, you can use list_apps (requires User Auth Key) to see all your applications and their respective IDs.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
