Once connected, send this to your chosen AI:

Using only SignalBase, list the five latest Bernstein reports with their dates, titles and authors.

If the AI calls the library and returns the report list, you are ready to ask your research questions.

GOOD TO KNOW

Common questions.

Where do I get my username and password?

Contact the person who invited you to SignalBase. Library credentials are provided separately from your OpenAI or Claude account. Public self-service registration is not currently available.

Why does sign-in open xuanagent.com?

SignalBase currently uses the existing xuanagent.com identity service. This is the expected authorization flow. Continue to use https://signalbase.fans/mcp as your MCP server URL.

Do I change my password on every platform?

No. All clients share the same library account and new password. Your temporary password is only for first sign-in. Do not send passwords in chat.

Do I reconnect when I change computers?

Codex and Claude Code usually store authorization on the current computer. Configure and sign in again on a new computer. Web connectors may follow your platform account; click Connect to authorize again if prompted.

What should I do if a connection fails?

Check that the URL includes /mcp, the Client ID matches the platform, and Client Secret is blank. If it still fails, send your inviter the client name, error text and time. Do not include passwords, tokens or callback URLs containing authorization codes.
