Core is an account-level Claude connector. Add it once and it is available for the same signed-in account across Claude on the web, Desktop, and mobile.
Open Claude from Core
During Core onboarding, choose Claude and select Open Claude. Core opens Anthropic's official connector page with the name and your personalized Secure server address already filled in.
- Review the prefilled name and address.
- Select Add.
- Approve Core when the sign-in window opens.
- Return to Core. The Claude status changes to Connected after Claude makes its first authenticated context check. You can finish onboarding while Core waits.
Keep the full personalized address, including its setup_attempt query parameter. It lets Core recognize this exact onboarding connection.
Manual fallback
If the prefilled page does not open, open Claude Settings, choose Connectors, select Add custom connector, and enter:
- Name:
Core - Remote MCP server URL: the complete Secure server address shown by Core
Select Add and approve Core. Outside onboarding, use https://core.gradien.ai/mcp/continuity.
No local process or configuration file is required. If Core is already connected to this Claude account, do not install it again for Claude Desktop or mobile. Start a new conversation if Core does not appear immediately.
