Overview

A read-only MCP server that lets an AI client search and read your QuestLaw research library.

Project status

QuestLaw MCP is an experimental, open-source project for connecting your QuestLaw library to AI tools.

The server decrypts your library on your own machine, from a .qlvault export generated via the extension. It is read-only and makes no network connections.

Disclaimer

This project is not part of the official, supported QuestLaw product suite.

Using it decrypts your library on your computer and gives the readable contents to the AI client you connect it to. That client sends what it reads to its provider. The server itself sends nothing anywhere, but it cannot control what the client or the provider does with what it receives. Please use it with that in mind, and read SECURITY.md before you connect a library that holds sensitive information.

How it works

  1. In QuestLaw, use the Export tool to create an encrypted file of your library (questlaw-backup-.qlvault).
  2. The server looks for the newest export file in the folder you choose.
  3. It decrypts the file in memory with your account key. Your library is never written to disk unencrypted.
  4. It builds a search index and answers tool calls.

Quick start

npx -y questlaw-mcp@0.5.1 setup

setup shows the disclosure and asks you to accept it, stores your account key in the OS secret store, finds your newest export, test-decrypts it, and prints the configuration for your client. To check an install later:

npx -y questlaw-mcp@0.5.1 doctor

From a clone, run the same commands as node bin/questlaw-library-mcp.js setup and node bin/questlaw-library-mcp.js doctor. Once doctor passes, choose an install method below.

Set up and install
