How do I use Logseq MCP Server?

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., "@Logseq MCP Server Search for blocks mentioning 'Project Apollo' and list the action items" 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.
