Claude Desktop uses the same account-level connectors as Claude on the web and mobile. If you connected Core from onboarding or Claude web under the same account, there is nothing else to install.
Open a new conversation in Claude Desktop and check that Core is available. If it does not appear, restart Claude Desktop and confirm that you are signed in to the same Claude account.
If Core is not connected to the account yet, follow the Claude setup guide. During onboarding, use Core's Open Claude action so the connector name and personalized address are already filled in. The manual Remote MCP server URL flow is only a fallback.
Do not use claude mcp add for Claude Desktop. That command configures Claude Code, which is a separate developer client.
