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": {
    "bach-filecommander": {
      "command": "npx",
      "args": [
        "-y",
        "bach-filecommander-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add bach-filecommander -- npx -y bach-filecommander-mcp

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "bach-filecommander": {
      "command": "npx",
      "args": [
        "-y",
        "bach-filecommander-mcp"
      ]
    }
  }
}

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": {
    "bach-filecommander": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "bach-filecommander-mcp"
      ]
    }
  }
}

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.

Common questions

Is BACH FileCommander 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 (1.7.0) reached the registry 9 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?

README from the maker

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

ellmos FileCommander MCP Server

The README navigation lists the documentation languages available in this repository. FileCommander runtime messages and formatted responses support German (de), English (en), Spanish (es), Chinese (zh), Japanese (ja), Russian (ru), French (fr), Hindi (hi), Arabic (ar), Bengali (bn), and Portuguese (pt). This runtime list is separate from README translation availability. It covers generated runtime messages and formatted tool responses; MCP tool titles, discovery descriptions, and schema descriptions remain static English. Set FC_LANGUAGE to one of the supported codes before starting the server, or call fc_set_language during an active MCP session. fc_get_language reports the active language and all eleven supported codes. Unset or unsupported FC_LANGUAGE values fall back to German (de). Date and time formatting follows the active locale.

*Part of the ellmos-ai family.*

A comprehensive Model Context Protocol (MCP) server that gives AI assistants full filesystem access, bounded multi-file content search, process management, interactive shell sessions, and async filename search capabilities.

50 tools in a single server - everything an AI agent needs to interact with the local system.

Discovery keywords: local filesystem MCP server, multi-file content search MCP, safe delete MCP, Recycle Bin MCP server, process management MCP, interactive shell MCP, async file search for AI agents, cloud-lock-safe file operations, Markdown to PDF MCP, OCR MCP server, ZIP archive MCP.

Registry status: published on npm, indexed by jsDelivr, visible on LobeHub, listed on Glama, and prepared for the official MCP Registry via server.json. Some third-party directories still show older 43-tool metadata, so the canonical README/npm metadata should remain the source of truth until their reindex catches up.

[!NOTE]

For AI Agents & LLM Integrations:

FileCommander provides 50 specialized tools accessible via standard stdio transport. All tool names use the fc_ prefix to prevent namespace collisions. For LLMs, compact context and schema overviews are available in llms.txt and server.json.

Overview & Why FileCommander?

Most filesystem MCP servers only cover basic read/write operations. FileCommander goes further:

Safe Delete - Moves files to Recycle Bin (Windows) or Trash (macOS/Linux) instead of permanent deletion
Interactive Sessions - Start and interact with REPLs (Python, Node.js, shells) through the MCP protocol
Async Search - Search large directory trees in the background while the AI continues working
Explicit Content Search - Search literal text or regex across a bounded list of files without recursion or glob expansion
Process Management - List, start, and terminate system processes
String Replace - Edit files by matching unique strings with context validation
Format Conversion - Convert between JSON, CSV, INI, YAML, TOML, XML, and TOON
ZIP Archives - Create, extract, and list ZIP archives
File Checksums - MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashing with compare
OCR - Extract text from images (optional tesseract.js dependency)
Safety Mode - Toggle to route all deletes through Recycle Bin / Trash
Markdown Export - Convert Markdown to professional HTML/PDF with code blocks, tables, nested lists, blockquotes
Cloud-Lock Safe - Automatic copy+delete fallback when cloud sync filters (OneDrive, Dropbox, Google Drive, iCloud) block rename operations
Cloud Lock Diagnosis - Check whether a path is at risk of sync-filter conflicts before operating
Cross-platform - Works on Windows, macOS, and Linux with platform-specific optimizations
