mcp-logseq vs crystalline

mcp-logseq: This MCP server seamlessly integrates Claude with your LogSeq knowledge base, enabling AI-powered interaction for reading, creating, and managing pages. It enhances productivity through intelligent organization, automated content creation, and optional semantic vector search across your notes.; crystalline: Crystalline provides AI agents with crystallized intelligence, allowing them to accumulate and retain knowledge across sessions, unlike an LLM's fluid intelligence. It acts as a local search index on plain markdown files, enabling agents to onboard curated knowledge and capture new learnings, evolving from a stranger to a peer.
