Overview

Description from the maker (original English)

Advanced filesystem operations with strict security boundaries for AI agents

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

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: Other
  • You need to fill in: WORKSPACE_ROOT

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: WORKSPACE_ROOT

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

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": {
    "filesystem": {
      "command": "npx",
      "args": [
        "-y",
        "@ai-capabilities-suite/mcp-filesystem"
      ],
      "env": {
        "WORKSPACE_ROOT": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add filesystem --env WORKSPACE_ROOT=your-value -- npx -y @ai-capabilities-suite/mcp-filesystem

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": {
    "filesystem": {
      "command": "npx",
      "args": [
        "-y",
        "@ai-capabilities-suite/mcp-filesystem"
      ],
      "env": {
        "WORKSPACE_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": {
    "filesystem": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@ai-capabilities-suite/mcp-filesystem"
      ],
      "env": {
        "WORKSPACE_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

  • WORKSPACE_ROOT required env
    Absolute path to workspace directory (all operations confined here)

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

Common questions

Is MCP Filesystem 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?

You need to fill in: WORKSPACE_ROOT

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 (0.1.9) reached the registry 11 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?

🚀 AI Capability Extension Suite

What if AI agents could actually _see_, _debug_, and _control_ your development environment?

We've built the most comprehensive suite of MCP servers that give AI agents superpowers they've never had before. This isn't just another tool collection—it's a paradigm shift that transforms AI assistants from code generators into intelligent development partners with runtime visibility, system control, and physical world access.

📝 Note: All packages have been split into individual Git submodules with their own repositories for better maintainability and independent versioning. Each package now has its own dedicated repository under the Digital-Defiance organization.

🤔 The Problem We're Solving

AI agents today are powerful but blind:

  • ❌ Can't see what code actually does when it runs
  • ❌ Can't capture your screen or record demonstrations
  • ❌ Can't manage files beyond basic read/write
  • ❌ Can't control processes or applications
  • ❌ Can't interact with your actual development environment

Result: You're stuck doing manual work that AI should handle.


🎯 What We've Built: The Complete Solution

The AI Capability Extension Suite provides 5 comprehensive MCP servers that give AI agents professional-grade capabilities, plus Akira:

🐛 1. MCP ACS Debugger

The most comprehensive debugging interface for AI agents - our flagship product

Repositories: Core | Server | VS Code Extension

✨ Now available as a VS Code extension! Install from Marketplace →

The Problem: AI agents were blind to runtime behavior. They could read your code and suggest fixes, but couldn't see what was actually happening when your code ran. Debugging remained a frustratingly manual process.

The Solution: AI agents can now debug like senior developers—setting breakpoints, inspecting variables, profiling performance, and detecting infinite loops in real-time. Available as both a standalone MCP server and a native VS Code extension with GitHub Copilot integration.

For AI Agents:

  • Runtime visibility—See what's actually happening when code executes
  • Interactive debugging—Set breakpoints, step through code, inspect state
  • Performance analysis—Profile CPU, memory, and execution timelines
  • Intelligent problem solving—Combine static analysis with runtime behavior
🛠️ 25+ Professional Debugging Tools

  • 🔍 Variable inspection (evaluate expressions, inspect objects, watch variables)
  • 🗺️ Call stack navigation (get stack, switch frames)
  • ⚠️ Hang detection (intelligent infinite loop identification)

Advanced Breakpoints (4 tools):

  • 📝 Logpoints - Non-breaking observation with variable interpolation
  • 🚨 Exception breakpoints - Break on caught/uncaught exceptions with filtering
