How do I use KeyID Agent Kit?

1. Click on "Deploy 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., "@KeyID Agent Kit Check my inbox and summarize the latest message from Alice" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.
