Overview

Description from the maker (original English)

Safe folder access for ChatGPT and Claude: read, write and search files, risky tools opt-in.

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 in the cloud
  • Transport: Streamable HTTP
  • 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 the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

You need

Which app do you use?

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

Works in Claude on the web, desktop and mobile:

  1. Open Settings → Connectors
  2. Press Add custom connector
  3. Paste the address below and press Add
  4. If it asks you to sign in, sign in with the maker
SettingsConnectors1+ Add2https://…3
https://freerdc.sjaman.deno.net/mcp

Run this in your terminal

claude mcp add --transport http freerdc https://freerdc.sjaman.deno.net/mcp

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "freerdc": {
      "url": "https://freerdc.sjaman.deno.net/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": {
    "freerdc": {
      "type": "http",
      "url": "https://freerdc.sjaman.deno.net/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.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker
SettingsConnectors1+ Create2https://…3
https://freerdc.sjaman.deno.net/mcp

Menu names can differ slightly by plan and over time.

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

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

Common questions

Is FreeRDC 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 in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Context7, Codebase Memory, Exa

FreeRDC

Give ChatGPT and Claude access to the folders you choose — and nothing else.

FreeRDC is an MCP server for file work with AI assistants. It reads, writes, searches and edits files and documents inside the folders you approve, and refuses everything outside them. Anything that can run commands, click the screen or shut the machine down is off unless you turn it on.

Why FreeRDC

  • Containment first. Paths outside your approved folders, .. traversal and symlink escapes are rejected before any file is touched. Protected paths such as device keys are denied even inside a root.
  • Risky tools are opt-in. Shell, GUI and system tools are disabled by default. The desktop extension exposes 23 file and document tools out of the box and 84 only when you enable local power.
  • Every tool is described and annotated. In the desktop extension, each tool has a title, a description, input and output schemas, and read-only / destructive / open-world hints, so the assistant knows what it is about to do.
  • Local. The desktop extension runs on your Mac. Your files are not sent to FreeRDC servers.
  • Audited. Every operation is written to a hash-chained audit log, with a STOP file kill switch.

Get started

Claude Desktop (desktop extension)
  1. Download freerdc-0.1.0.mcpb from Releases.
  2. Open it with Claude Desktop and pick the folder(s) FreeRDC may use.
  3. Leave local power tools off unless you need shell or GUI access.

Requires macOS and Node.js 22+. Details and privacy policy: mcpb/README.md.

ChatGPT (self-hosted)

Run the server locally and reach it privately through OpenAI Secure MCP Tunnel. Do not expose the local listener to the public internet. See docs/OPENAI-INTEGRATION.md and docs/DEPLOYMENT.md.

ChatGPT hosted connector (early access)

The hosted connector is in review for the ChatGPT app directory. Until it is listed, add it in ChatGPT developer mode with the MCP URL https://freerdc.sjaman.deno.net/mcp.

  1. Connect FreeRDC in ChatGPT. The sign-in page shows a 10-character pairing code (letters A–Z and digits 2–9).
  2. Download freerdc-agent-hosted.mjs from Releases. Requires Node.js 22+.
  3. Pair this computer, choosing the folder ChatGPT may use:
   node freerdc-agent-hosted.mjs connect --server https://freerdc.sjaman.deno.net/mcp --code YOUR_CODE --device-id my-mac --root /absolute/allowed/folder
  1. Keep the agent running while you use FreeRDC:
   node freerdc-agent-hosted.mjs run --device-id my-mac

The pairing code expires after about 10 minutes. The agent is a prebuilt binary; its source is not included in this repository.

Run from source

Requires Node.js 22+, npm and Git.

npm ci

npm run build node packages/server/dist/src/cli.js --root /absolute/allowed/folder --port 8787

The server binds to 127.0.0.1 only, requires at least one explicit root, stores state under ~/.freerdc, and leaves process tools disabled. Create ~/.freerdc/STOP to activate the kill switch. Pick the narrowest folder that fits the task — never add credentials, caches or unrelated projects to a root.

Installer scripts

macOS or Linux:

curl -fsSLo install.sh https://raw.githubusercontent.com/danielarif26/freerdc/main/install.sh

sh install.sh

Windows PowerShell:

Invoke-WebRequest https://raw.githubusercontent.com/danielarif26/freerdc/main/install.ps1 -OutFile install.ps1

.\install.ps1

The installers follow the mutable main branch. For higher assurance, review a commit or tag and pin it with FREERDC_REF= . Rerun with --uninstall (macOS/Linux) or -Uninstall (Windows) to remove an installer-managed copy.
