Which MCP Server Should You Choose?
Choose Worldku Memory when:
You need dedicated capabilities in the Knowledge & Memory domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Save AI conversations into your Worldku memory and recall them from any MCP client.
Local memory layer over the session histories coding agents already write (Claude Code, Codex CLI, opencode): lexical search, recall tools, session-start auto-recall, secret redaction at index time, cross-machine sync over SSH.
Worldku Memory is categorized under Knowledge & Memory and uses a remote streaming HTTP/SSE transport. In contrast, Deja Vu belongs to Knowledge & Memory using local stdio subprocess. Select Worldku Memory when you need capabilities focused on knowledge & memory and Deja Vu when you require tools for knowledge & memory.
