Enables AI agents to store and retrieve project context, bugs, decisions, and session logs by reading and appending markdown files in a local Obsidian vault, without requiring any cloud services.

Lets an AI agent list, read, search, and (when individually enabled) write Markdown notes and manage a task list in one sandboxed root folder. Access is read-only by default, with each write tool enabled by name and all paths confined to that folder.

A local MCP server for low-token co-reading: import a book, split it into chapter-sized chunks, read it chunk by chunk, and keep notes so a session can resume without re-reading the whole book.
