Introduction

Pack is a personal knowledge base for you and your agents. You write Markdown documents; Pack indexes them for semantic search, and exposes the same corpus through an MCP server so external agents read and write alongside you.

What Pack gives you

• A Markdown editor with autosave, versioning, and typed @ refs between documents.
• Tags with colors, namespaces, and folder inheritance — tag a folder, everything inside carries it.
• Semantic search over everything you’ve written, with tag filters.
• An MCP server + CLI so Claude Desktop, Cursor, any MCP client, or your terminal can read and write your corpus.
