What can you do with this server?

The 404K Knowledge Planet MCP Server allows MCP clients to access and search a private archive of Knowledge Planet topics from 404k.wlhtea.xyz. It provides the following tools: * Status Check: View the last synchronization time, total topic count, media statistics, and remaining login session validity. * Browse Topics: Paginate through archived topics in reverse chronological order, with optional filters for content type (digest/featured, images, files) and pagination controls. * Search Topics: Perform keyword searches across topic titles, content, and tags. Refine results with filters such as excluded keywords, exact tag matching, time range (e.g., today, last 7 days, custom dates), content type, sorting (newest, oldest, popular), and pagination. * Get Topic Details: Retrieve full topic content by ID, including the complete text, author-specific segments, images with protected URLs, and links to attachments like PDFs. All interactions are authenticated via an Authorization: Bearer API token, with no Knowledge Planet cookie required.

How do I use 404K Knowledge Planet 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., "@404K Knowledge Planet MCP Server search for topics about machine learning" 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.
