Tools MCP Server

What is Tools?

Tools is an MCP server for interacting with Markdown knowledge bases—folders containing .md files with YAML metadata (title, tags, url). It exposes tools to retrieve content by tag, text, slug/URL, or date range, and to manage tags. It is intended for users with large collections of Markdown files that exceed typical context windows or span multiple knowledge bases.

How to use Tools?

Clone the library-mcp repository, ensure uv is installed, then configure Claude Desktop by editing claude_desktop_config.json to point uv at main.py with a directory of Markdown content. After restarting Claude, you can invoke tools like get_by_tag or get_by_date_range through natural language queries.
