Overview

Description from the maker (original English)

Plain-English security checks for AI-built apps (Trivy + Opengrep), with fix requests for 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: APPLEDGER_KEY

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: APPLEDGER_MODE, APPLEDGER_KEY

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • PyPIPython’s uv installed (for the uvx 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": {
    "appledger": {
      "command": "uvx",
      "args": [
        "appledger",
        "mcp"
      ],
      "env": {
        "APPLEDGER_MODE": "your-value",
        "APPLEDGER_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add appledger --env APPLEDGER_MODE=your-value --env APPLEDGER_KEY=your-value -- uvx appledger mcp

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": {
    "appledger": {
      "command": "uvx",
      "args": [
        "appledger",
        "mcp"
      ],
      "env": {
        "APPLEDGER_MODE": "your-value",
        "APPLEDGER_KEY": "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": {
    "appledger": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "appledger",
        "mcp"
      ],
      "env": {
        "APPLEDGER_MODE": "your-value",
        "APPLEDGER_KEY": "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

  • APPLEDGER_MODE env
    hosted (default): files Git would commit are sent to appledger.net, scanned and deleted. local: Trivy and Opengrep run on this machine.
  • APPLEDGER_KEY secret env
    Optional dashboard connection key (al_...). Without it, nothing goes to a dashboard; a hosted check returns a link that saves its result to a free account (the summary is kept up to 24 hours).

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

Common questions

Is AppLedger 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: APPLEDGER_KEY

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 (0.2.5) reached the registry 23 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, Symantec Cloud DLP AIops

AppLedger honest check

Honest security feedback, in plain language, for apps people build with AI tools such as Claude Code, Codex, Cursor and Lovable.

AppLedger checks your app folder with independent scanners and explains what they find in everyday words: what is wrong, why it matters, and what to do. It also writes a fix request you can hand straight to the AI tool that built the app, then checks again.

What it checks

ScannerFinds
TrivyLeaked passwords and keys, outdated libraries with known security problems, risky container setup
OpengrepDangerous code patterns: SQL injection, command injection, unsafe data loading, debug mode left on
SonarQube (optional, local mode)Code quality and more security hotspots, if you already run a SonarQube server

Each run produces, in /.appledger/:

  • report.html: a score, who may use the app right now (only you, your team, the whole company), and every problem in plain words
  • fix-prompt.md: a ready-made fix request for your coding agent
  • findings.json: the same findings for tools and dashboards

Two ways to run

ModeWhat you installWhere your code goes
Hosted (default)Only this packageSource files Git would commit are zipped, sent over HTTPS to appledger.net, scanned and deleted right after. Secret files are never sent. You confirm before the first upload of each folder
Local (--local or APPLEDGER_MODE=local)Also Trivy, Opengrep and the Opengrep rulesStays on your computer. With a connection key, only a summary goes to your dashboard (see below); --no-dashboard skips even that

What gets uploaded in hosted mode

  • Sent: files Git would commit (git ls-files, including new files that aren't ignored). Outside a Git repository, .gitignore is still honoured.
  • Never sent: .env and .env.* (except .env.example, .env.sample, .env.template), *.pem, *.key, *.p12, *.pfx, SSH keys, .npmrc, .pypirc, .netrc, *credentials*.json, service-account*.json, secrets.*, the folders cert, certs, secrets, .ssh and .aws, .claude/settings.local.json, Terraform state, password files, Ansible Vault files, Kubernetes/Helm secret manifests, certificates and similar (full list in src/appledger/uploadpolicy.py). The server drops such files again as a second safety net.
  • Skipped: dependencies, build output, media, documents and data files (CSV, spreadsheets, slides, SQL, logs, data dumps) and files over 1 MB.

If a secret file is committed to Git or not ignored, the check reports it as a problem by file name. Its content is never read or sent.

See exactly what would be sent, and what is left out and why, without uploading anything:

python -m appledger path/to/your-app --list-files

The first hosted check of a folder asks you to confirm. In scripts and scheduled runs, pass --yes. If the code belongs to your employer or a client, make sure you're allowed to upload it, or use local mode.

Install

Claude Code plugin (recommended: adds the guided check-my-app skill):

claude plugin marketplace add contentasoftware/appledger

claude plugin install appledger@appledger

In the Claude Code desktop app, add the marketplace contentasoftware/appledger in the plugin settings instead. Start a new session, then ask: "Is my app safe to share?" or "Add this app to AppLedger".

MCP server only (needs uv):

claude mcp add appledger -- uvx --from appledger appledger-mcp

Command line:

pip install appledger

python -m appledger path/to/your-app

Step-by-step guide with troubleshooting: https://appledger.net/docs/

Version 0.2.0 (upload preview, consent, secret-file exclusion, scheduling) is being released to PyPI; until then pip install appledger gets 0.1.x.

Company dashboard

Create a free account at appledger.net to keep every app your people check in one ledger: owner, grade, score trend, who may use it and which AI tool built it. Create a connection key under "Connect a computer", then save it on each computer:

python -m appledger --connect al_your_key

Or tell Claude: "Connect AppLedger with this key: al_…". The key is saved in ~/.appledger/key; APPLEDGER_KEY overrides it and --disconnect removes it.

From then on each check also saves a summary to your dashboard: the app's name, score, grade, problem counts, the list of problems found (level and short title, up to 60; never code or file paths), and the scanners used. Never the code.

Not connected yet? From 0.2.3, a hosted check from a computer without a key ends with a save link, also shown in report.html:

Save this result to a free AppLedger ledger (link works for 24 hours): https://appledger.net/app/claim.php?t=...

Open it, create a free account or log in, and the check is in your ledger; the page then offers a key for that computer. Until the link is used, the service keeps only the check's summary (app name, score, the problems' levels and titles; never code), for up to 24 hours. A link works once; --no-dashboard turns it off.

You can also add an app in the web app with Add app: register it without code, or upload a zip to check it in the browser (the zip is scanned and deleted the same way).

Scheduled checks

python -m appledger path/to/your-app --schedule weekly --yes   # or daily

python -m appledger --schedules # list python -m appledger path/to/your-app --schedule off # stop

Uses Windows Task Scheduler on Windows and cron on macOS and Linux. Hosted scheduled checks need the one-time --yes consent; add --local to schedule local checks instead. --quiet prints one line per check.

Local mode setup

  1. Trivy: winget install AquaSecurity.Trivy (Windows) or brew install trivy (Mac)
  2. Opengrep: download from the releases page and put it on your PATH
  3. Rules: git clone --depth 1 https://github.com/opengrep/opengrep-rules.git ~/.appledger/opengrep-rules
  4. Check: python -m appledger --doctor
