vault-cortex vs seekstone

vault-cortex: Vault Cortex is an MCP server enabling AI agents to interact with Obsidian vaults, offering hybrid search, task management, and structured memory without needing Obsidian to run. It provides remote access and ensures data integrity, facilitating advanced AI-driven knowledge management workflows.; seekstone: Seekstone is an Obsidian Model Context Protocol (MCP) server that provides AI agents like Claude direct read and write access to your Obsidian vault. It operates filesystem-direct, eliminating the need for the Obsidian app or its Local REST API plugin, offering significantly faster search and drastically reduced context window usage compared to other MCP servers.
