Big Brain MCP

Big Brain MCP is a community-driven Model Context Protocol server that provides AI assistants with a unified 'second brain' interface. It allows agents to search, read, capture, and manage notes, projects, and tasks stored as plain markdown files. It is designed to work with local folders or existing Obsidian vaults, enabling deterministic retrieval via fuzzy search, wikilinks, and tags without requiring API keys or cloud dependencies.
