What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs on your computer
Transport: stdio
Category: Search & AI memory

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
You fill in yourself: PROJECT_ROOT

You need

npmNode.js installed (for the npx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "claudex": {
      "command": "npx",
      "args": [
        "-y",
        "@kunwarshah/claudex"
      ],
      "env": {
        "PROJECT_ROOT": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add claudex --env PROJECT_ROOT=your-value -- npx -y @kunwarshah/claudex

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "claudex": {
      "command": "npx",
      "args": [
        "-y",
        "@kunwarshah/claudex"
      ],
      "env": {
        "PROJECT_ROOT": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "claudex": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@kunwarshah/claudex"
      ],
      "env": {
        "PROJECT_ROOT": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

PROJECT_ROOT env
Path to Claude Code conversation log directory. Defaults to ~/.claude/projects.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Claudex safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.3.4) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

🚀 Quick Start

Prerequisites

Node.js 18+ and npm
Claude Code installed with conversation history in ~/.claude/projects

Installation

Option 1: npm (Recommended)

# Global installation

npm install -g @kunwarshah/claudex [https://www.npmjs.com/package/@kunwarshah/claudex]

Then run anywhere:

claudex

Custom port (if 3400 is in use):

claudex --port 3500

Custom project directory:

claudex --project-root ~/my-claude-projects

Or use without installing (npx):

npx @kunwarshah/claudex

Add MCP Server (gives Claude Code persistent memory):

claude mcp add --transport stdio claudex -- claudex-mcp

See the MCP Server Guide for details.

CLI Options:

--help, -h: Show help message
--version, -v: Show version
--port, -p : Custom server port (default: 3400)
--project-root : Custom Claude projects directory

Environment Variables:

PORT: Server port (default: 3400)
PROJECT_ROOT: Claude projects directory (default: ~/.claude/projects)

Option 2: From Source

Clone the repository:

git clone https://github.com/kunwar-shah/claudex.git

cd claudex

Run system check (optional but recommended):

npm run check

This validates your environment and catches common setup issues.

Install dependencies (or use auto-fix):

# Option 1: Manual installation

npm install cd server && npm install && cd .. cd client && npm install && cd ..

Option 2: Auto-fix (installs deps + creates .env)

npm run check:fix

Configure environment (if not using auto-fix):

cd server

cp .env.example .env

Edit .env if needed (default: PROJECT_ROOT=~/.claude/projects)

cd ..

Start the application:

# Automatically runs system check, then starts servers

npm run dev

Open your browser: http://localhost:3000

The backend API runs on http://localhost:3400

System Checker

Claudex includes a comprehensive system checker that validates your environment:

# Quick check

npm run check

Detailed output

npm run check:verbose

Auto-fix common issues

npm run check:fix

JSON output (for CI/CD)

npm run check:json

What it checks:

✅ Node.js & npm versions
✅ PROJECT_ROOT path & permissions
✅ Port availability (3000, 3400)
✅ Dependencies installation
✅ Claude Code data (projects, sessions)
✅ JSONL file validity
✅ Database permissions
✅ Search index status
