Step 3 - Connect from Claude
In any Claude conversation, type:
First-Time Authentication
The first time you connect, xysq needs to verify your identity:- Claude will receive an
auth_url- a browser link will open automatically (or you can open it manually). - Complete sign-in or approval in the xysq app.
- Once approved, return to Claude - the session will show as authenticated.
- The server may return a
device_code. Use this on futureauthenticatecalls so you are not asked to re-approve every session. Claude Desktop normally persists this automatically.
Adding Memories
Once connected, you can ask Claude to remember anything for future sessions:Video Walkthrough

Troubleshooting
| Problem | Fix |
|---|---|
| MCP does not appear in Claude | Confirm your connector URL is correct and that you clicked Save. Fully quit and reopen Claude Desktop - MCP changes require a full restart. |
| Still old behavior after editing | Quit Claude completely (including from the menu bar / system tray), then reopen. A window close is not enough. |
| Authentication loop / keeps asking to sign in | Make sure you’re using the device_code returned after first auth. If lost, remove the connector and re-add it to restart the flow. |
| ”Connection refused” or network error | Check that https://api.xysq.ai/mcp is accessible from your network. If you are on a VPN or corporate network, it may be blocked. |
| Enterprise or managed installs | Your IT team may restrict MCP or redirect config paths. Contact your administrator for the correct setup path. |
| Connector saves but Claude can’t reach xysq | Double-check that Configure: Allow All was selected when setting up the connector. |
