atlas-mcp-server vs vir

atlas-mcp-server: ATLAS (Adaptive Task & Logic Automation System) is an MCP server designed for LLM Agents to manage projects, tasks, and knowledge. It utilizes a 3-node architecture (Projects, Tasks, Knowledge) and a Neo4j graph database to provide comprehensive management capabilities and standardized communication.; vir: Vir reads Claude Code session transcripts, distills durable knowledge into typed Markdown notes in your Obsidian vault, and feeds the best insights back into CLAUDE.md files. It treats Obsidian as the primary frontend with deep integration, supporting retroactive processing of existing sessions. The tool includes confidence scoring, opt-in sync, MCP server, and upcoming Obsidian plugin.
