Terminology

MCP (Model Context Protocol)A standard protocol created by Anthropic that lets AI models like Claude directly access external tools and file systems. Think of it as a spec for plugging 'plugins' into AI.

Obsidian VaultThe local folder unit where notes are stored in Obsidian. A collection of markdown (.md) files, making it a great structure for passing context to AI.

Context WindowThe maximum text length an AI model can process at once. Claude's is up to 200K tokens, allowing multiple long notes to be passed at once.
