Before you install Ext Apps

Ext Apps has not been scanned by AgenticMart yet. It has no open-source license we can detect, so it can only be scanned once the maintainer claims it. Until then, here is what it can likely access and what to check before you install it.

What it can access

  • An MCP server is a program your AI app starts and talks to. A local one runs with your user's permissions: it can see the files, environment variables and network your account can.

Before you install

  1. Pin the version you reviewed instead of always installing the latest release.
  2. Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.
  • Maintained by modelcontextprotocol on GitHub, 3,031 stars and 424 forks. Popularity is not proof of safety.
  • Last code change: Oct 29, 2026.
  • No open-source license detected: check the repository before using it commercially.
