RAG Vault MCP Server

Your documents. Your machine. Your control. RAG Vault lets your AI coding assistant search your private documents, things like API specs, research papers, and internal docs. Everything runs locally and your data stays on your machine unless you choose to pull in content from a remote URL.

People connecting AI & ML tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "robthepcguy-rag-vault": {
      "command": "npx",
      "args": [
        "-y",
