1. Click on "Install Server".

2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.

3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@kimi-webbridge-mcp Open my Gmail and show unread emails"

That's it! The server will respond to your query, and you can continue using it as needed.
