Hillnote MCP Server is the official Model Context Protocol server for Hillnote that enables AI assistants to interact with Hillnote document workspaces programmatically. It currently supports macOS and is designed to work with the Hillnote Desktop App, with Windows support coming soon. The server exposes a comprehensive capability set across multiple domains: multi-workspace management for handling several document collections; document management with full CRUD operations; smart search featuring fuzzy ranking across titles, tags, and content; content manipulation with validation and preview; AI recipes to manage and execute prompts; HTML tools to build interactive utilities; tasklist management for Kanban-style boards with full task CRUD operations; and rich metadata support for tags, emojis, and descriptions. Configuration automatically discovers Hillnote workspaces from the app configuration at ~/Library/Application Support/Hillnote/workspaces.json, with examples for both npm-based and source installations. Requirements include macOS, Hillnote Desktop App for macOS, Node.js >= 18, and an MCP-compatible client (Claude Desktop, Cursor, VS Code, etc.). Documents use Markdown with YAML frontmatter, aligning with Hillnote’s document format.
