openzim-mcp vs rekal

openzim-mcp: OpenZIM MCP is a server that enables AI models to access and search ZIM format knowledge bases offline. It provides intelligent structured access, smart navigation, context-aware discovery, and performance optimizations for LLMs. The server supports dual modes (simple and advanced), streamable HTTP transport, batch entry retrieval, and multi-archive search.; rekal: rekal provides long-term memory for LLMs via an MCP server. It stores memories in a local SQLite file and retrieves them using hybrid search (BM25 keywords + vector semantics + recency decay). It works with any MCP-capable agent like Claude Code, Codex CLI, and OpenCode.
