Overview

What is Knowledge_vault?

Knowledge_vault is a local knowledge management MCP server built with the FastMCP framework and Python. It enables users to store, search, and manage knowledge records directly on their machine, with features like automatic title generation, tag suggestion, and fuzzy search. It is intended for developers and power users who want a private, file-based knowledge base integrated with MCP-compatible clients (e.g., Claude Desktop).

How to use Knowledge_vault?

After installing dependencies with uv, add the server configuration to your Claude Desktop config file (~/.config/claude_desktop_config.json) using the provided JSON snippet, then restart Claude Desktop. Use natural language commands like “Store a programming tip: …” or “Search for Python knowledge” to interact with the server.
