Do I need an API key?

No. The hosted endpoint is ready to connect; product and free-use limits apply.

What should I do after connecting?

Ask for a concrete task, such as “research the current BTC-USD price and show the source.”

Can I use more than one client?

Yes. Add the same hosted URL to each client independently.

My client does not appear above.

Look for its hosted MCP, remote server, or custom connector URL field. Do not use a local stdio command for this endpoint.
