openzim-mcp vs mimirs

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.; mimirs: Mímirs provides persistent project memory for AI coding agents, reducing token consumption and context overhead through local indexing, semantic search, cross-session memory, and dependency graphs. It works with multiple editors and is privacy-preserving with no cloud dependencies. The tool achieves 90-98% recall@10 on real codebases.
