Use the complete Secure server address shown by Core during onboarding, including `?setup_attempt=...`. Outside onboarding, use `https://core.gradien.ai/mcp/continuity`.

## Add Core in Cursor

1. Open Cursor Settings.
2. Open Tools & MCPs.
3. If Cursor shows a migration notice, select Open Tools & MCPs in Customize.
4. Select New MCP Server or Add a Custom MCP Server.
5. Enter `Core` and paste the complete Core address.
6. Connect and approve Core in the browser.
7. Reload Cursor or run Developer: Reload Window if Core remains disabled.

For global manual configuration, preserve the other entries in `~/.cursor/mcp.json` and add:

```json
{
  "mcpServers": {
    "core": {
      "url": "<secure-server-address>"
    }
  }
}
```

Use the global config when Core should follow the user across projects. Use `.cursor/mcp.json` only for a project-scoped setup.

If Cursor remains on Waiting for callback or Exchanging token after approval, quit and relaunch Cursor once, then inspect Output, MCP Logs. Do not keep creating duplicate Core entries or paste a long-lived connector key into the file during normal setup.
