Safeinstall MCP Server

Supply-chain security for the AI-agent era. The install gate for npm , pnpm , and bun - for the humans who type install , the AI agents that run it for them, and the config that programs those agents. It runs locally over stdio via the published package.

People connecting security tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add mickdownunder-safeinstall -- npx -y safeinstall-cli

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "mickdownunder-safeinstall": {
      "command": "npx",
      "args": [
        "-y",
        "safeinstall-cli"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package safeinstall-cli - unscoped; check the name against the project README before installing

registry namespace io.github.Mickdownunder is GitHub-verified and matches the repo owner

03 · What Safeinstall can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

Limitations (from the README)

- Not a CVE scanner - pair with npm audit or Snyk for vulnerability data - Transitive dependencies are evaluated for install scripts and untrusted sources when transitive.mode is enabled. Release-age, typo-squat, and provenance still apply to direct dependencies only. - Transitive install-script detection is npm-only - pnpm lockfiles do not record install-script presence. Transitive untrusted-source detection works f
