Frequently asked questions
Can my AI automatically find the Player ID for a specific user to send a test push?
Yes! Use the list_users tool. Your agent will respond with complete metadata for registered devices, including unique Player IDs and tags, allowing you to trigger targeted pushes instantly.
How do I find my OneSignal App ID and REST API Key?
Log in to OneSignal, select your app, navigate to Settings > Keys & IDs, and you will find your unique App ID and secret REST API key there.
Can I use the AI to cancel a scheduled notification?
Absolutely. Use the cancel_notification tool with the Notification ID. The agent will instruct OneSignal to stop the broadcast immediately, provided it hasn't been fully delivered yet.
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.
