OneSignal MCP server questions

Does OneSignal have an official MCP server?

Yes. OneSignal publishes its MCP server itself. OneSignal's own documentation describes it. MartechDB only lists servers a vendor publishes, never community copies.

What is the OneSignal MCP server URL?

The address is https://api.onesignal.com/mcp/oauth.

Does the OneSignal MCP server need an API key?

No. You sign in with your OneSignal account (OAuth), and your AI client handles the rest.

How do I connect OneSignal MCP to Claude, ChatGPT or Cursor?

In Claude, add https://api.onesignal.com/mcp/oauth as a custom connector (Customize, Connectors, Add custom connector). In ChatGPT, turn on developer mode (Settings, Apps, Advanced settings) and create an app with the same address. In Cursor, use the Add to Cursor link on MartechDB's page, or paste the JSON settings into your mcp.json. In Claude Code, run: claude mcp add --transport http onesignal https://api.onesignal.com/mcp/oauth
