Our reading of AppLedger, from the data

AppLedger is a security MCP server from contentasoftware, listed in the official MCP Registry.

We haven't measured its tool list yet, so its token cost is unknown.

Maintenance is active: the last public signal was 4 days ago (2026-10-14). For comparison, 67% of security servers are active or maintained.

With 0 GitHub stars it ranks #579 of 1,263 security servers we index.

It runs locally on your machine over stdio and needs one secret (APPLEDGER_KEY); use a scoped, least-privilege key.

Install AppLedger MCP server

claude mcp add appledger -e APPLEDGER_KEY='<appledger-key>' -- uvx appledger mcp

{
  "mcpServers": {
    "appledger": {
      "command": "uvx",
      "args": [
        "appledger",

  }
}

Add to ~/.cursor/mcp.json (global) or .cursor/mcp.json (project).

{
  "mcpServers": {
    "appledger": {
      "command": "uvx",

Configuration

Variable	Required	Secret	Description
APPLEDGER_MODE	—	—	hosted (default): files Git would commit are sent to appledger.net, scanned and deleted. local: Trivy and Opengrep run on this machine.
APPLEDGER_KEY	—	yes	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).
