NeuroStack
Connects Claude (or any MCP client) to your Markdown vaults with tiered search that goes from keyword matching to semantic embeddings and GraphRAG connections. Runs locally via Ollama or cloud via their hosted endpoint. The 24 exposed tools include read-only operations for search, graph analysis, and stale note detection, plus four opt-in git-backed write tools (vault_write_file, vault_delete_file, vault_read_file, vault_list_files) that commit every change with descriptive messages. Useful when you want your AI to remember context across sessions without re-pasting notes, or when you need it to catch deprecated information before citing it. Works with Obsidian folders, Logseq, Notion exports, or any collection of .md files.
